PHP Switch Statement
Conditional statements are used to perform different actions based on different conditions.
The PHP Switch Statement
Use the switch statement to select one of many blocks
of code to be executed.
Syntax
switch (n)
{
case label1:
code to be executed if n=label1;
break;
case label2:
code to be executed if n=label2;
break;
default:
code to be executed if n is different from both label1 and label2;
} |
This is how it works: First we have a single expression n (most often a
variable), that is evaluated once. The value of the expression is then compared
with the values for each case in the structure. If there is a match, the block
of code associated with that case is executed. Use break to prevent the
code from running into the next case automatically. The default statement is used if no
match is found.
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> |
