Doc #69853 [NEW]: break behavior unspecified when no argument is specified
From: chealer at gmail dot com
Operating system:
PHP version: Irrelevant
Package: Documentation problem
Bug Type: Documentation Problem
Bug description:break behavior unspecified when no argument is specified
Description:
------------
---
From manual page: http://www.php.net/control-structures.break
---
"break accepts an optional numeric argument which tells it how many
nested enclosing structures are to be broken out of."
The documentation does not specify what happens if break's optional is
not provided. Therefore, the effect of a "break;" statement inside
several concerned structures (as happens at the end of the example) is
unspecified. As of PHP 5.4, the effect appears to be that of "break
1;".
Comment http://php.net/manual/en/control-structures.break.php#90308
confirms.
Test script:
---------------
<?php
foreach(array(1, 2) as $iteration) {
var_dump($iteration);
foreach (array() as $dummy) {
break;
}
}
?>
Actual result:
--------------
int 1
int 2
