how do i exit from a loop/ stop a loop ?

how do i exit from a for loop ... for e.g....

 

<?php>
for ($b=0; $b<=$num; $b++) {
        if ($char[$b]==".")
        {
         
        }
       }
?>

 

i'm checking it finds one ".", it stops looping.

<?

$b = "";

for ($b=0; $b<=$num; $b++) {

        if ($char[$b]==".")

        {

       

        }

      }

?>

[clearstatcache]

<?

$b = "";

for ($b=0; $b<=$num; $b++) {

        if ($char[$b]==".")    <<==== is this? the condition that will terminate the loop?

        {

            break;

        }

}

?>
