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 " Middle<br>\n";
while (1) {
echo " Inner<br>\n";
continue 3;
}
echo "This never gets output.<br>\n";
}
echo "Neither does this.<br>\n";
}
