<source lang="html4strict">

<?
$arr = array( "one", "two", "three", "four", "stop", "five" );
while ( list( , $val ) = each( $arr ) ) {
if ( $val == "stop" ) {
break; /* You could also write "break 1;" here. */
}
echo "$val<br>\n";
}
$i = 0;
while ( ++$i ) {
switch ( $i ) {
case 5:
echo "At 5<br>\n";
break 1; /* Exit only the switch. */
case 10:
echo "At 10; quitting<br>\n";
break 2; /* Exit the switch and the while. */

==Breaking a Loop==



<source lang="html4strict">

<?php

==Break Statement==



<source lang="html4strict">

<html>
<head>

switch($k) {
case 1:
print "I: $i, J: $j, K: $k\n";
break 2;
case 2:
print "I: $i, J: $j, K: $k\n";
break 3;

==Using break to avoid division by zero==



<source lang="html4strict">
