seems that are more subtle reasons for two different variations of "and" and "or" operators. see the example: <?php $a="test"; $b=1; $res= $a || $b; echo $res."\n\n"; $a="test"; $b=1; $res= $a or $b; echo $res."\n\n"; ?> If the difference between the or and || operator is only the precedence we can expect the same output from both the "echo" instructions. This is the result: 1 test So seems that the '||' operator convert in "bool" the result of logical expression. This is not the same behaviour of the 'or' operator. You can verify from yourself adding var_dump() before the echo. ---- Server IP: 213.92.11.19 Probable Submitter: 85.18.136.70 ---- Manual Page -- http://www.php.net/manual/en/language.operators.logical.php Edit -- https://master.php.net/note/edit/73786 Del: integrated -- https://master.php.net/note/delete/73786/integrated Del: useless -- https://master.php.net/note/delete/73786/useless Del: bad code -- https://master.php.net/note/delete/73786/bad+code Del: spam -- https://master.php.net/note/delete/73786/spam Del: non-english -- https://master.php.net/note/delete/73786/non-english Del: in docs -- https://master.php.net/note/delete/73786/in+docs Del: other reasons-- https://master.php.net/note/delete/73786 Reject -- https://master.php.net/note/reject/73786 Search -- https://master.php.net/manage/user-notes.php
