note 82246 added to language.operators.comparison

To lukzboz ~ at ~ gmx ~ dot ~ net : It IS stated that, when compared to integers, strings are converted to a numeric value according to these rules : http://fr.php.net/manual/en/language.types.string.php Since $txt does not begin with valid numerical data, its numeric value is 0. If you try with $txt = '12 reasons I should type my variables', your code won't print anything. <?php $txt = 'yoursimpletext'; if( $txt == 0 ) { echo $txt.' == 0'; } else { echo $txt.' != 0'; } // Prints 'yoursimpletext == 0' $txt = '12 reasons I should type my variables'; if( $txt == 0 ) { echo $txt.' == 0'; } else { echo $txt.' != 0'; } // Prints '12 reasons I should type my variables != 0' var_dump( $txt ); // Prints 'string(37) "12 reasons I should type my variable" var_dump( (int) $txt ); // Prints 'int(12)' ?> ---- Server IP: 217.174.223.124 Probable Submitter: 193.189.91.57 ---- Manual Page -- http://www.php.net/manual/en/language.operators.comparison.php Edit -- https://master.php.net/note/edit/82246 Del: integrated -- https://master.php.net/note/delete/82246/integrated Del: useless -- https://master.php.net/note/delete/82246/useless Del: bad code -- https://master.php.net/note/delete/82246/bad+code Del: spam -- https://master.php.net/note/delete/82246/spam Del: non-english -- https://master.php.net/note/delete/82246/non-english Del: in docs -- https://master.php.net/note/delete/82246/in+docs Del: other reasons-- https://master.php.net/note/delete/82246 Reject -- https://master.php.net/note/reject/82246 Search -- https://master.php.net/manage/user-notes.php
