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

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