Php Switch Statement
The switch statement in PHP is used to perform one of several different actions based on one of several different conditions. so you can see our php switch statement example.
Syntax
switch(expression)
{
case label1:
code to be executed if expression = label1;
break;
case label2:
code to be executed if expression = label2;
break;
default:
code to be executed
if expression is different
from both label1 and label2
}
Example
<html>
<body>
<?php
switch ($x)
{
case 1:
echo "Number 1";
break;
case 2:
echo "Number 2";
break;
case 3:
echo "Number 3";
break;
default:
echo "No number between 1 and 3";
}
?>
</body>
</html>
- A single expression (most often a variable) is evaluated once.
- The value of the expression is compared with the values for each case in the structure.
- If there is match, the code associated with that case is executed.
- After a code is executed, break is used to stop the code from running into the next case.
- The default statement is used if none of the cases are true.
