note 106131 added to language.operators.comparison

Please be careful when comparing strings with floats, especally when you are using the , as decimal. <?php var_dump($alt); var_dump($neu); var_dump($alt == $neu); ?> string(9) "590217,73" float(590217,73) bool(false) not the float is cast to a string and then string-compared, but the string is cast to a float and then float-compared. to compare as strings use strval! <?php var_dump(strval($alt)); var_dump(strval($neu)); var_dump(strval($alt) == strval($neu)); ?> string(9) "590217,73" string(9) "590217,73" bool(true) ---- Server IP: 217.160.235.204 Probable Submitter: 78.50.226.216 ---- Manual Page -- http://www.php.net/manual/en/language.operators.comparison.php Edit -- https://master.php.net/note/edit/106131 Del: integrated -- https://master.php.net/note/delete/106131/integrated Del: useless -- https://master.php.net/note/delete/106131/useless Del: bad code -- https://master.php.net/note/delete/106131/bad+code Del: spam -- https://master.php.net/note/delete/106131/spam Del: non-english -- https://master.php.net/note/delete/106131/non-english Del: in docs -- https://master.php.net/note/delete/106131/in+docs Del: other reasons-- https://master.php.net/note/delete/106131 Reject -- https://master.php.net/note/reject/106131 Search -- https://master.php.net/manage/user-notes.php
