(PHP 4, PHP 5, PHP 7, PHP 8)
break ends execution of the current
for, foreach,
while, do-while or
switch structure.
break accepts an optional numeric argument
which tells it how many nested enclosing structures are to be
broken out of. The default value is 1, only
the immediate enclosing structure is broken out of.
<?php
$arr = array('one', 'two', 'three', 'four', 'stop', 'five');
foreach ($arr as $val) {
if ($val == 'stop') {
break; /* You could also write 'break 1;' here. */
}
echo "$val\n";

Using the optional argument:
<?php
$i = 0;
while (++$i) {
switch ($i) {
case 5:
echo "At 5\n";
break 1; /* Exit only the switch. */
case 10:
echo "At 10; quitting\n";
break 2; /* Exit the switch and the while. */
default:
break;
}
echo "$i\n";
