skip current iteration

I have a php array $numbers = array(1,2,3,4,5,6,7,8,9)

if I am looping over it using a foreach foreach($numbers as $number)

and have an if statement if($number == 4)

what would the line of code be after that that would skip anything after that line and start the loop at 5? break, return, exit?

Solution 1:

You are looking for the continue statement. Also useful is break which will exit the loop completely. Both statements work with all variations of loop, ie. for, foreach and while.

$numbers = array( 1, 2, 3, 4, 5, 6, 7, 8, 9 );
foreach( $numbers as $number ) {
    if ( $number == 4 ) { continue; }
    // ... snip
}

Solution 2:

continue;

Continue will tell it to skip the current iteration block, but continue on with the rest of the loop. Works in all scenerios (for, while, etc.)

Solution 3:

Break; will stop the loop and make compiler out side the loop. while continue; will just skip current one and go to next cycle. like:

$i = 0;
while ($i++)
{
    if ($i == 3)
    {
        continue;
    }
    if ($i == 5)
    {
        break;
    }
    echo $i . "\n";
}

Output:

1
2
4
6 <- this won't happen

Solution 4:

I suppose you are looking for continue statement. Have a look at http://php.net/manual/en/control-structures.continue.php
