note 116960 added to function.is-float

Coercing the value to float and back to string was a neat trick. You can also just add a literal 0 to whatever you're checking. <?php function isfloat($value) { // PHP automagically tries to coerce $value to a number return is_float($value + 0); } ?> Seems to work ok: <?php isfloat("5.0" + 0); // true isfloat("5.0"); // false isfloat(5 + 0); // false isfloat(5.0 + 0); // false isfloat('a' + 0); // false ?> YMMV ---- Server IP: 72.52.91.14 Probable Submitter: 65.65.116.130 ---- Manual Page -- http://php.net/manual/en/function.is-float.php Edit -- https://master.php.net/note/edit/116960 Del: integrated -- https://master.php.net/note/delete/116960/integrated Del: useless -- https://master.php.net/note/delete/116960/useless Del: bad code -- https://master.php.net/note/delete/116960/bad+code Del: spam -- https://master.php.net/note/delete/116960/spam Del: non-english -- https://master.php.net/note/delete/116960/non-english Del: in docs -- https://master.php.net/note/delete/116960/in+docs Del: other reasons-- https://master.php.net/note/delete/116960 Reject -- https://master.php.net/note/reject/116960 Search -- https://master.php.net/manage/user-notes.php
