A variable, in the context of programming, is a symbolic name given to an unknown quantity that permits the name to be used independent of the information it represents. Variables are associated with data storage locations, and values of a variable are normally changed during the course of prog...
What is a variable declaration? A variable declaration is a statement that sets the name of a variable and its data type. It also provides information about where the variable should be stored in memory. This process can include initializing the variable with an initial value, although that is...
Argument definition An argument is a way for you to provide more information to a function. The function can then use that information as it runs, like a variable. Said differently, when you create a function, you can pass in data in the form of an argument, also called a parameter. Ar...
A variable is an identifier that refers to the data item stored at a particular memory location. This data item can be accessed in the program simply by using the variable name. The value of a variable can be changed by assigning different values to it a
A variable is an object whose value may change during execution of a program. It is a memory location used to store a data value. A variable name should be carefully chosen by the programmer so that its use is reflected in a useful way in the entire prog

In short, a value is some assigned meaning to a variable (the object containing the value) For example type=boolean; name=help; variable=a storage location; value=what is stored in that location; Further break down: X = 2; where X is a variable while 2 is the value stored in X. ...
Any variable declared outside of any function is within this global scope. Example: <?php $foo = 'bar'; function myFunc() { $baz = 42; } $foo is in the global scope, $baz is in a local scope inside myFunc. Only code inside myFunc has access to $baz. Only ...

Enumerations are used as user-defined types. Variables of this type can be assigned a range of values restricted to the enumerators contained in the enumeration. So, if defining a variable that contains the colors of a rainbow, you declare the variable like this:...
