Question

I have a loop that is doing some error checking in my PHP code. Originally it looked something like this…

foreach($results as $result) {     if (!$condition) {         $halt = true;         ErrorHandler::addErrorToStack('Unexpected result.');     }      doSomething();  }  if (!$halt) {     // do what I want cos I know there was no error } 

This works all well and good, but it is still looping through despite after one error it needn’t. Is there a way to escape the loop?

You are looking for the break statement.

$arr = array('one', 'two', 'three', 'four', 'stop', 'five'); while (list(, $val) = each($arr)) {     if ($val == 'stop') {         break;    /* You could also write 'break 1;' here. */     }     echo '$val<br />\n'; }
