Continue is used in the loop structure to skip the remaining code in this loop and start the next loop when the condition evaluates to True.

Note: Notice that the switch statement in PHP is considered a looping structure that can use continue.

Continue accepts an optional numeric parameter to decide to skip a few loops to the end of the loop. The default value is 1, which jumps to the end of the current loop.

<?phpwhile (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 causes confusion. The following examples indicate that this should not be done.

<?php for  ($i = 0; $i < 5; + + $i) {      if ($i = = 2)          continue      print "$i \ n";  }? >

The desired result is:

0134

The actual output can be:

2
