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"; } ?> |
