PHP 5 FunctionsThe real power of PHP comes from its functions; it has more than 1000 built-in functions. PHP User Defined FunctionsBesides the built-in PHP functions, we can create our own functions. A function is a block of statements that can be used repeatedly in a program. A function will not execute immediately when a page loads. A function will be executed by a call to the function.
PHP 5 for LoopsPHP for loops execute a block of code a specified number of times. The PHP for LoopThe for loop is used when you know in advance how many times the script should run. Syntaxfor (init counter; test counter; increment counter) { code to be executed; } Parameters:
PHP 5 while LoopsPHP while loops execute a block of code while the specified condition is true. PHP LoopsOften when you write code, you want the same block of code to run over and over again in a row. Instead of adding several almost equal code-lines in a script, we can use loops to perform a task like this. In PHP, we have the following looping statements:
PHP 5 if...else...elseif StatementsConditional statements are used to perform different actions based on different conditions. PHP Conditional StatementsVery often when you write code, you want to perform different actions for different decisions. You can use conditional statements in your code to do this. In PHP we have the following conditional statements:
PHP 5 ConstantsConstants are like variables except that once they are defined they cannot be changed or undefined. PHP ConstantsA constant is an identifier (name) for a simple value. The value cannot be changed during the script. A valid constant name starts with a letter or underscore (no $ sign before the constant name). Note: Unlike variables, constants are automatically global across the entire script. |
