Understanding Arrays in PHP

An array is a systemic arrangement of objects. Hum, what does this mean? Well in programming an array is a type of data structure. Each array can hold several pieces of information. It’s sort of like a variable in that it stores data, but not at all like a variable in that instead of storing one bit of information it can store many pieces of information. Let’s start with an example. Let’s say that you are storing information about people. You could have a variable that stored my name â€Å"Angela†. But in an array, you could store my name, my age, my height, my In this sample code, we will look at storing two bits of information at a time, the first being somebody’s name and the second being their favorite color. In this example code, you can see that the friend array is sorted by number, and contains a list of friends. In the second array, color, instead of using numbers it uses strings to identify the different bits of information. The identifier used to retrieve data from the array is called it’s key. In our first example, the keys were integers 0, 1, 2, and 3. In our second example, the keys were strings. In both cases, we are able to access the data held in the array by using both the array’s name, and the key. Like variables, arrays always start with a dollar sign ($array) and they are case sensitive. They can not start with an underscore or a number, you must start them with a letter. So, to put it simply, an array is kind of like a variable with lots of little variables inside of it. But what exactly do you do with an array? And how is it useful to you as a PHP programmer? In practice, you will probably never create an array like the one in the example above. The most useful thing you can do with an array in PHP is to use it to hold information you get form somewhere else. Having your websites information stored in an MySQL database is not uncommon. When your website needs certain information it simply accesses your database, and wha-laa, on demand data. Let’s say you have a database of people who live in your city. You now want to search that database and print out records for anyone named â€Å"Tom†. How would you go about doing this? You would read through the database for people named Tom, and then pull their name and all the other information about them from the database, and place it in an array inside of your program. You are then able to cycle through this array, and print out the information or store it to use elsewhere in your program. On the surface, an array might not look that interesting to you, but when you do more programming and start storing more complex data structures you will find you are often writing them to arrays when they need to be used.

Understanding the Decisions to Drop The Atomic Bomb Essay

The death of thousands in a moment, this was the power of the weapon the United States held in their possession. It was nearly the end of World War II. With Germany defeated and the Allied Forces ready for the cease-fire, only the Axis power of Japan stood in the way of the end of the World War. Worried about Nazi Germany’s technological advances earlier in the war, the United States began to research atomic energy and the possibility of creating an atomic bomb (Walker 10). When the bombs were created, the arguments for and against the use of it were gruesome, lengthy, and all understandable in some way. During the decision to drop atomic bombs on Japan, President Harry S. Truman and his fellow politicians had to consider the ethical†¦show more content†¦The use of this bomb would mean saving both military supplies and American lives at the cost of the Japanese. (9) Though few could see much trouble with such an outcome, the scientists had another way at looking at th ese options. Though the scientists themselves were the ones to encourage the creation of the atom bomb, their plans and views differed immensely from those of the military. As World War II raged on, Germany was suspected of harnessing atomic energy and directing it into powering a weapon. Albert Einstein, agreeing with Leo Silzard, the man who first thought into the concept, urged President Franklin D. Roosevelt to look further into the study of atomic energy and the possibility of using it for a bomb. President Roosevelt, fearing the German’s advances in this study, quickly agreed and sent money to the University of Chicago to begin the study and research of atomic energy. (Roleff 62) (The Manhattan Project 1) Upon sending this money, the top-secret research program and building of the atomic bomb began. Later moving from Chicago to Los Alamos, New Mexico, this secret project was called the Manhattan Project. (1) Einstein later explained that his recommendation to the president was to onl y further the United State’s knowledge of this energy and to have an extra line of defense if the Germans were to ever launch a nuclear attack.

Early childhood free essay sample

Our work as men and women raising children is important because our influence lasts a lifetime. But what are the most important gifts we give our children? Self-love, self-concept, and self-esteem. Self-Love * Self-love is the most essential of all skills. It is concepts children learn from the way parents (and other adults) treat them. Children first need to know that they are loved and accepted for who they are. With this as a basis, their natural impulse is to take that love and learn to contribute it to the world in constructive ways. It is not difficult then, to see that self-love is the best gift we can give our children. *love in children, as in adults, means liking themselves, enjoying themselves, and accepting themselves. Children need to know that although parents may not always like what they do, or have done, we still like and love them. There is a great difference between rejecting a child’s behaviour and rejecting the child. We will write a custom essay sample on Early childhood or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Help the child understand that he or she is a human being and as a human being he or she will make mistakes. Our goal is to help children learn from those mistakes and assist them in making corrections. Self-Concept *Self-concept is the image we have of ourselves. It means liking ourselves just the way we are. To teach children about self-concept, we must look at them without labels or comparisons. If a child is taller than most of the other children in his or her class, he or she may feel awkward. However, if the child is taught that his or her height is an asset of which to be proud, the child will grow up with respect for him- or herself and others. *There are things about every child that are unique. It is by zeroing in on each special quality—whether it is their willingness to let someone else ride their trike, their whimsical sense of humour, or their ability to carry a tune—that we give children a positive sense of self. Children take great pride and delight in the knowledge that there is no one exactly like them in the world. Share a child’s uniqueness by looking into his or her eyes with a smile that says, â€Å"You are special. I love to be with you! † Self-Esteem *Self-esteem has been defined as â€Å"the sense of being lovable and capable. † When these two qualities are in sync, a child has high self-esteem. *Children learn about themselves and know themselves only by reflection. For the first important years of their lives, parents are the major influence providing this reflection to the child. Later on, teachers and friends in addition to parents provide this reflection. Reaction: As a parent, we want to make right and wonderful for our children, we want our children a happiest child of all, and we want to eliminate conflict, disappointment, rejection, and failure from their lives. But we need to remember that life is a process. Of all us will encounter difficult situation, trouble, worry, and complication as they move through life. As they grow up they encounter and experience some unexpected things to happen . the best thing to do is to explain and feel them that they are not alone in their ups and down. Child may feel different emotions. We should not reject them we should listen to them even though it is nonsense. Also we should help our child look for strengths by helping him/her experience success and in every success they did they should receive reward by encourage them. Parent’s guidance and presence is highly recommended we should always aware for our child’s feeling or condition regarding with their emotional and physical. Because child is delicate sensitive they get easily get hurt especially in a situation that they don’t understands what is happening. Therefore, the most important task as a parent is by giving them love and care and a strong sense of self-love, self-concept, self-esteem that we prepare them to learn what life is all about for them also to understand what life is why is there circumstances happen in every life. That child that has a sense of self-love, self-esteem and self-concept has a high self-confidence and has strength emotion that can lead them to be a successful one.

Well-known figures of the revolutionary epoch disappointment in the results of their achievements. This is what Engels wrote about this: Suppose these people imagine that they can seize power well, so what? The way only they pierce a hole that would destroy the dam, the flow itself quickly put an end to their illusions. But if it so happened that these illusions would have given them a great strength of will, whether it is necessary to complain about? People boast that made the revolution, always be sure the next day, they did not know what they were doing, that the revolution made quite unlike the one that they wanted to do. This is what Hegel called the irony of history, that irony which escaped a few historical figures. So that the social illusion oddly enough, but this is precisely what has raised so far in the a ccomplishment and the intelligentsia, and the people in the struggle for change in their living conditions.

Plea Bargains Essay Example

Plea Bargains Essay Example Plea Bargains Paper Plea Bargains Paper Plea-bargaining can mean many things to many people, in and out of the courtroom. Let us first start by defining plea bargain. Plea bargain is defined an agreement in which the defendant enters a guilty plea in exchange for a reduced sentence. This is the technical meaning, but as I stated before, the word plea bargain can mean very different things to very different people. To the accused, the word plea bargain means a freedom of choice. To the prosecutor, it means a lesser workload. To the Judge, it means saving his time and the courts time, and to the state, a plea bargain means saving money. In my perception, the word plea bargain means a failure of the American trial system. The Constitution grants us, the citizens of this country, a right to speedy trial by jury of our peers. Where exactly do you see that right, which is rightfully ours, in plea bargains? How can our trial and court system not bestow the punishment that fits the crime? When we give the accused freedom of choice, isn’t that an oxymoron? The only effectiveness I can see in the court system plea bargains is that solely the courts are benefitting from them. The courts save time, money and the prosecutors save themselves from a huge workload. Plea bargains have no effectiveness on the justice. How are the victims given justice if the accused gets a far lesser sentence and punishment than is fairly just? How can the accused learn their lesson when they have the freedom to choose a lesser punishment? How does the public perceive our trial system as fair and just when plea bargains are being over used to save time and money? Plea bargaining is not a useful tool. The court systems, in order to save themselves from a trial, â€Å"†¦forces the party into a situation where they have to take a guess about what the evidence is, about how strong the case might be, and they have to make that guess against the background of enormously severe penalties if you guess wrong. † (Schulhofer, 2004) Even though defendants are innocent, they do not know if they will be proved innocent or guilty without a reasonable doubt when in front of a jury. They are pressured into taking a guilty plea because they cannot afford the risk of going to trial. The court systems are unable to sort out the guilty people from the innocent and that is the main reason this system of plea bargaining is not a useful tool to the courts, the public, the defendants and the victims. The word plea bargain may mean many different things to many different people but what we must understand is that plea bargain has many more cons than pros for both the faith of the people in the criminal justice system as well as the victims. Our justice system should be fair and just for all but all it seems to do is save time and money for the state and put many innocent people in jail and give the freedom of choice. It is time to change our trial and court systems to reflect what our founding fathers initially desired from it, the right to a speedy trial from our jury of peers, because the only people plea bargains benefit are the GUILTY!
