What is a PHP switch?
The PHP switch statement is used to execute an instruction under many other conditions. It more or less works like PHP if-else-if.
Syntax switch Statement:
switch (n) {
case value1:
code to be executed if n=lvalue;
break;
case value2:
code to be executed if n=value2;
break;
case value3:
code to be executed if n=value3;
break;
... default:
code to be executed if n is different from all values;
}
?>
1. default is an optional statement.
2. Each case can have a break statement, used to finish sequence of statement.
3. break statement is optional to use in switch.
4. PHP allows you to use number, character, string, as well as functions in switch expression.
5. Nesting of switch statements is allowed
6. You can use semicolon (;) instead of colon (:).
PHP switch Statement
The default statement is used if no match is found.
<?php
$my_num=36;
switch($my_num){
case 12:
echo("My favorite number is equal to 12");
break;
case 24:
echo("My favorite number is equal to 24");
break;
case 36:
echo("My favorite number is equal to 36");
break;
default:
echo("My favorite number is not equal to 12, 24 or 36");
}
?>
Output: My favorite number is equal to 36
