PHP is a popular scripting language for Web developers, because it enables the seamless integration of dynamic and interactive content with HTML. The analysis system for PHP creates tokens from the encoding syntax, such as "T_Variable" syntax "$ foo." PHP allows programmers, variables to store values in a variety of formats on how to use such as numeric strings, characters, or memory addresses. Learn how you insert a T_Variable in PHP can perform operations on dynamic information, such as in a program, the area calculated on the basis of user entered height and width.
Instructions
1. Name of the variable. Start the T_Variable name with the characters "$" ($). Lead the dollar sign with the name of the variable. Use an underscore (_), to start the variable name if the name starts with a number or break apart words within the name. For example "$ _99balloons" or "$ Purchase_date" are both valid variable name.
2. you have a scope for the variable. Set the variable outside the function you define the variable for all of the code as a global variable. You give to the variable inside a function
3. set define as "local", only within this function defined. the variable as static or dynamic. You determine whether you should lose their value the variable at the end of each function or if you can change functions, the value of the variable. For example, code, the one the variables to (e.g. $X + 1) can always only the value of $X, if you define it as static. Type the keyword "static" before the variable definition functions change the value of the variable.
4. Definieren you the variable. Use the operator "=" (equal), to set the value of the variable. For example "$ foo = bar" defines the variable "$ foo" with the value "Bar." Type "echo($foo)" to PHP return "Bar." "
