note 96219 added to book.array

Be careful when adding elements to a numeric array. I wanted to store some info about some items from a database and decided to use the record id as a key. $key=3000000000; $DATA[$key]=true; This will create an array of 30 million elements and chances are, you will use up all memory with these 2 lines $key=3000000000; $DATA["$key"]=true; This on the other hand will force the array to be an associative array and will only create the one element ---- Server IP: 69.147.83.197 Probable Submitter: 71.211.175.208 ---- Manual Page -- http://www.php.net/manual/en/book.array.php Edit -- https://master.php.net/note/edit/96219 Del: integrated -- https://master.php.net/note/delete/96219/integrated Del: useless -- https://master.php.net/note/delete/96219/useless Del: bad code -- https://master.php.net/note/delete/96219/bad+code Del: spam -- https://master.php.net/note/delete/96219/spam Del: non-english -- https://master.php.net/note/delete/96219/non-english Del: in docs -- https://master.php.net/note/delete/96219/in+docs Del: other reasons-- https://master.php.net/note/delete/96219 Reject -- https://master.php.net/note/reject/96219 Search -- https://master.php.net/manage/user-notes.php
