`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 "&nbsp;&nbsp;Middle<br />\n";

        while (1) {

            echo "&nbsp;&nbsp;Inner<br />\n";

            continue 3;

        }

        echo "This never gets output.<br />\n";

    }

    echo "Neither does this.<br />\n";

}

?>

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 :

but this script will output :

because the return value of the print() call is int(1), and it will look like the optional numeric argument mentioned above.

I noticed that continue would not work within a switch statement too, for example :



<?php



$names = array("Mike", "Mary", "Jose", "Anna");

foreach ($names as $kid) {

switch($kid) {

case "Mike":

case "Anna": continue; break;

}

echo $kid."<br />";

}

?>



This will NOT work as expected. It will produce:



Mike

Mary

Jose

Anna



BUT, if you specify the level of brackets to jump out of for the  continue it will work as expected. So you should have the following code:



<?php 

$names = array("Mike", "Mary", "Jose", "Anna");

foreach ($names as $kid) {

switch($kid) {

case "Mike":

case "Anna": continue 2; break;

}

echo $kid."<br />";

}

?>



This WILL work as expected: It will produce:



Mary

Jose

continue seems not to work with switch !

this exemple : 

<?php

$i = 0;

switch($i) {

case 1 : echo 1 . '<br />'; continue;

case 2 : echo 2 . '<br />'; continue;

default : $i++; continue;

}

echo $i;

?>



return 1, the switch is called only once !

if (!($key % 2)) { // skip odd members

       continue;

   }



Note that this skips even members, not odd as written. Just a sidenote :) (Of course, this might be because numbering starts at 0, but essentially it'll skip over 0, 2, 4....)

a possible solution for 

greg AT laundrymat.tv



I've got the same problem as Greg

and now it works very fine by using

return() instead of continue.



It seems, that you have to use return()

if you have a file included and

you want to continue with the next loop

You using continue in a file included in a loop will produce an error.  For example:



//page1.php

for($x=0;$x<10;$x++)

   {

    include('page2.php');    

}



//page2.php



if($x==5)

    continue;

else 

   print $x;



it should print



"012346789" no five, but it produces an error:



Cannot break/continue 1 level in etc.

In the same way that one can append a number to the end of a break statement to indicate the "loop" level upon which one wishes to 'break' , one can append a number to the end of a 'continue' statement to acheive the same goal. Here's a quick example:



<?

    for ($i = 0;$i<3;$i++) {

        echo "Start Of I loop\n";

        for ($j=0;;$j++) {

            

            if ($j >= 2) continue 2; // This "continue" applies to the "$i" loop 

            echo "I : $i J : $j"."\n";

        }

        echo "End\n";

    }

?>



The output here is:

Start Of I loop

I : 0 J : 0

I : 0 J : 1

Start Of I loop

I : 1 J : 0

I : 1 J : 1

Start Of I loop

I : 2 J : 0

I : 2 J : 1



For more information, see the php manual's entry for the 'break' statement.
