note 107516 added to control-structures.break

Correction to [Miguel Cruz 15-Apr-2009 12:37], at least in php 5.3: "'break 0', while allowed, does nothing" is not true. break 0 (and break -1) act just like break without an argument or break 1. Here's the code (which also confirms the findings of [RK 17-Dec-2010 04:09]) -- <?php function break_level($i) { while (true) : break $i; echo "printed WITHIN function control structure when \$i = " . $i . "<br />"; endwhile; echo "printed AFTER function control structure when \$i = " . $i . "<br />"; } break_level(-1); // => outputs "printed AFTER function control structure when $i = -1" break_level(0); // => outputs "printed AFTER function control structure when $i = 0" break_level(1); // => outputs "printed AFTER function control structure when $i = 1" break_level(2); // => Fatal error: "Cannot break/continue 2 levels in [program_name] on line 4" echo "printed after LAST CALL to function when \$i = " . $i . "<br />"; ?> ---- Server IP: 69.147.83.197 Probable Submitter: 72.219.151.91 ---- Manual Page -- http://www.php.net/manual/en/control-structures.break.php Edit -- https://master.php.net/note/edit/107516 Del: integrated -- https://master.php.net/note/delete/107516/integrated Del: useless -- https://master.php.net/note/delete/107516/useless Del: bad code -- https://master.php.net/note/delete/107516/bad+code Del: spam -- https://master.php.net/note/delete/107516/spam Del: non-english -- https://master.php.net/note/delete/107516/non-english Del: in docs -- https://master.php.net/note/delete/107516/in+docs Del: other reasons-- https://master.php.net/note/delete/107516 Reject -- https://master.php.net/note/reject/107516 Search -- https://master.php.net/manage/user-notes.php
