continue

(PHP 4, PHP 5, PHP 7, PHP 8)

continue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.

Note:

In PHP the switch statement is considered a looping structure for the purposes of continue. continue behaves like break (when no arguments are passed) but will raise a warning as this is likely to be a mistake. If a switch is inside a loop, continue 2 will continue with the next iteration of the outer loop.

continue accepts an optional numeric argument which tells it how many levels of enclosing loops it should skip to the end of. The default value is 1, thus skipping to the end of the current loop.

<?phpforeach ($arr as $key => $value) {    if (!($key % 2)) { // skip even members        continue;    }    do_something_odd($value);}$i = 0;while ($i++ < 5) {    echo "Outer<br />\n";    while (1) {        echo "Middle<br />\n";        while (1) {            echo "Inner<br />\n";            continue 3;        }        echo "This never gets output.<br />\n";    }    echo "Neither does this.<br />\n";}?>

Omitting the semicolon after continue can lead to confusion. Here's an example of what you shouldn't do.

<?phpfor ($i = 0; $i < 5; ++$i) {    if ($i == 2)        continue    print "$i\n";}?>

One can expect the result to be:

0
1
3
4
