Note Submitter: shadow4.at-jouwmoeder,dot-nl ---- 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? :)
