PHP Conditional Statements
Very often when you write code, you want to perform different actions for different conditions. You can use conditional statements in your code to do this.
In PHP we have the following conditional statements:
if
statement - executes some code if one condition is trueif...else
statement - executes some code if a condition is true and another code if that condition is falseif...elseif...else
statement - executes different codes for more than two conditionsswitch
statement - selects one of many blocks of code to be executed
PHP - The if Statement
The if
statement executes some code if one condition is true.
Syntax
if (condition) {
// code to be executed if condition is true;
}
