Says the documentation: "A key may be either an integer or a string... Floats in key are truncated to integer." $ php -r '$a[2.3] = "foo"; var_dump($a);' array(1) { [2]=> string(3) "foo" } Previous Comments: ------------------------------------------------------------------------ [2008-04-24 21:41:58] dmitrij at stepanov dot lv Description: ------------ array_key_exists() does not accept float as a key. (The first argument should be either a string or an integer), however it is possible to use floats as keys. Reproduce code: --------------- $array =array( 3.15 =>20); var_dump( array_key_exists( 3.15, $array)) ."\n";// ERROR: The first argument should be either a string or an integer echo $array[3.15];//OK Expected result: ---------------- boolean(true) 20 Actual result: -------------- blahblahblah 20 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44825&edit=1
