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 " 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.
<?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.
