# `continue`

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

> Note: Note that in PHP the switch statement is considered a looping structure for the purposes of `continue`.

`continue` accepts an optional numeric argument which tells it how many levels of enclosing loops it should skip to the end of.

`<?php while (list ($key, $value) = each ($arr)) { if (!($key % 2)) { // skip odd members continue; } do_something_odd ($value); } $i = 0; while ($i++ < 5) { echo "Outer<br />\n"; while (1) { echo "&nbsp;&nbsp;Middle<br />\n"; while (1) { echo "&nbsp;&nbsp;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.

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

One can expect the result to be :

    0
    1
    3
    4

but this script will output :

    2

because the return value of the print() call is `int(1)`, and it will look like the optional numeric argument mentioned above.
