note 98373 added to function.is-array

Another version of function is_assoc_array(). It is not short, but seems to be quite effective. Main idea: when 'foreach' works on a list - it uses numbers as keys, and that keys are numbers, start with 0, and in sequenced order. Anything another - and array is not a list. <?php function is_assoc_array( $obj ) { if( ! is_array( $obj ) ) return false; $islist = true; foreach( $obj as $key => $val ) { if( gettype( $key ) == 'string' ) return true; if( isset( $prev_key ) && $key !== 0 ) { if( $key != $prev_key + 1 ) return true; } $prev_key = $key; } return false; } ?> ---- Server IP: 195.54.192.44 Probable Submitter: 127.0.0.1 ---- Manual Page -- http://www.php.net/manual/en/function.is-array.php Edit -- https://master.php.net/note/edit/98373 Del: integrated -- https://master.php.net/note/delete/98373/integrated Del: useless -- https://master.php.net/note/delete/98373/useless Del: bad code -- https://master.php.net/note/delete/98373/bad+code Del: spam -- https://master.php.net/note/delete/98373/spam Del: non-english -- https://master.php.net/note/delete/98373/non-english Del: in docs -- https://master.php.net/note/delete/98373/in+docs Del: other reasons-- https://master.php.net/note/delete/98373 Reject -- https://master.php.net/note/reject/98373 Search -- https://master.php.net/manage/user-notes.php
