switch statement is used to perform different actions according to a plurality of different conditions.
PHP Switch Statement
If you want to selectively execute one of several blocks of code, use a switch statement.
switch (n)
{
case label1:
If n = label1, where the code execution;
break;
case label2:
If n = label2, where the code execution;
break;
default:
If n is equal to neither equal nor label1 label2, where the code execution;
}
?>
How it works: First, a simple expression n (usually variable) once calculated. The value of the structure of an expression value of each case is compared. If there is a match, associated with the case code is executed. After the code is executed, the code used to prevent break jumped next case to continue. Default statement is executed when a match does not exist (i.e., no case is true).
$favcolor="red";
switch ($favcolor)
{
case "red":
echo "Your favorite color is red!";
break;
case "blue":
echo "Your favorite color is blue!";
break;
case "green":
echo "Your favorite color is green!";
break;
default:
echo "Your favorite color is not red, blue, or green!";
}
?>
