(PHP 4, PHP 5, PHP 7, PHP 8)
continue 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.
Note: In PHP the switch statement is considered a looping structure for the purposes of
continue.continuebehaves likebreak(when no arguments are passed) but will raise a warning as this is likely to be a mistake. If aswitchis inside a loop,continue 2will 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.
<?php
$arr = ['zero', 'one', 'two', 'three', 'four', 'five', 'six'];
foreach ($arr as $key => $value) {
if (0 === ($key % 2)) { // skip members with even key
continue;
}
echo $value . "\n";
}
?>The above examples will output:
one three five
<?php
$i = 0;
while ($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";
}
?>The above examples will output:
Outer Middle Inner Outer Middle Inner Outer Middle Inner Outer Middle Inner Outer Middle Inner
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

continue within a switch that is attempting to act like a break statement for the
switch will trigger an E_WARNING.
