note 69243 added to language.types.boolean

if ( $var ) will always result the exact same as if ( TRUE === (bool)$var ) That's interesting, since "a" turns to TRUE when (bool) is used and 0 turns to FALSE, though "a" == 0. The following example is self explaining: <?php $var = "a"; echo "\$var = $var<br/><br/>"; if ( $var ) echo 'if ( $var ) >> TRUE'; else echo 'if ( $var ) >> FALSE'; echo "<br/><br/>"; if ( TRUE === (bool)$var ) echo 'if ( TRUE === (bool)$var ) >> TRUE'; else echo 'if ( TRUE === (bool)$var ) >> FALSE'; echo "<br/><br/>though<br/><br/>"; if ( "a" == 0 ) echo "'a' == 0 >> TRUE"; else echo "'a' == 0 >> FALSE"; ?> I did not include if ( 0 ) because it's quite obvious that 0 will turn to FALSE, always. For whom doesn't understand: "a" is TRUE 0 is FALSE ( "a" == 0 ) is TRUE That's weird, isnt it? :) ---- Server IP: 194.109.193.119 Probable Submitter: 217.195.249.69 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.types.boolean.php Edit -- https://master.php.net/note/edit/69243 Del: integrated -- https://master.php.net/note/delete/69243/integrated Del: useless -- https://master.php.net/note/delete/69243/useless Del: bad code -- https://master.php.net/note/delete/69243/bad+code Del: spam -- https://master.php.net/note/delete/69243/spam Del: non-english -- https://master.php.net/note/delete/69243/non-english Del: in docs -- https://master.php.net/note/delete/69243/in+docs Del: other reasons-- https://master.php.net/note/delete/69243 Reject -- https://master.php.net/note/reject/69243 Search -- https://master.php.net/manage/user-notes.php
