note 73650 added to function.gettype

I wrote my own gettype function by just using the default is_? functions, but it took twice as long as gettype... So I decided to use gettype with a twist. Taking the warnings about gettype to heart, and depending on your custom needs, it's worthwhile to dynamically test the gettype result with a known variable, and link the result to a predefined result. Like so: <?php /* dynamically create an array by using known variable types link with a predefined value */ $R=array(); $R[gettype(.0)]='number'; $R[gettype(0)]='number'; $R[gettype(true)]='boolean'; $R[gettype('')]='string'; $R[gettype(null)]='null'; $R[gettype(array())]='array'; $R[gettype(new stdClass())]='object'; // what is function wis_($v){ global $R; return $R[gettype($v)]; } echo wis_('hello') . '<br/>'; // "string" echo wis_(24) . '<br/>'; // "number" echo wis_(0.24) . '<br/>'; // "number" echo wis_(null) . '<br/>'; // "null" echo wis_($R) . '<br/>'; // "array" ?> You won't need to worry about changes in gettype's return strings in future versions. If the result evaluates to false then you know the variable tested is some "other" type. I also find these useful <?php function is_num($v){return (is_int($v) || is_double($v));} function is_box($v){return (is_array($v)||is_object($v));} echo is_num(null) . '<br/>'; // false echo is_num(false) . '<br/>'; // false echo is_num('123') . '<br/>'; // false echo is_num(123) . '<br/>'; // true echo is_num(123.0) . '<br/>'; // true ?> ---- Server IP: 69.147.83.197 Probable Submitter: 74.118.123.241 ---- Manual Page -- http://www.php.net/manual/en/function.gettype.php Edit -- https://master.php.net/note/edit/73650 Del: integrated -- https://master.php.net/note/delete/73650/integrated Del: useless -- https://master.php.net/note/delete/73650/useless Del: bad code -- https://master.php.net/note/delete/73650/bad+code Del: spam -- https://master.php.net/note/delete/73650/spam Del: non-english -- https://master.php.net/note/delete/73650/non-english Del: in docs -- https://master.php.net/note/delete/73650/in+docs Del: other reasons-- https://master.php.net/note/delete/73650 Reject -- https://master.php.net/note/reject/73650 Search -- https://master.php.net/manage/user-notes.php
