PHP break Statement

Description

Sometimes a situation arises where we want to exit from a loop immediately without waiting to get back to the conditional statement.

The keyword break ends execution of the current for, foreach, while, do while or switch structure. When the keyword break executed inside a loop the control automatically passes to the first statement outside the loop. A break is usually associated with the if.

Example:

In the following example we test the value of $sum, if it is greater than 1500 the break statement terminate the execution of the code. As the echo statement is the first statement outside loop it will print the current value of $sum.

<?php
$array1=array(100, 1100, 200, 400, 900);
$x1=0;
$sum=0
while ($x1<=4)
{
if ($sum>1500)
{
break;
}
$sum = $sum+$array1[$x1];
$x1=$x1+1;
}
echo $sum;
?>

Output:

1800
