note 70348 added to language.types.string

Here's a nice one: <? $foo='test'; for($i=0;$i<10;$i++) { $bar="one$foo"; echo memory_get_usage()."\n"; } ?> Depending on your PHP configuration, you end up with the same value many times -- in my case, 12480 12488 12488 12488 12488 12488 12488 12488 12488 12488 Now, consider this example: <? $foo='test'; for($i=0;$i<10;$i++) { $bar="another$foo"; // <-- the only change is here echo memory_get_usage()."\n"; } ?> The result in this case, on my server, is: 12416 12432 12448 12464 12480 12496 12512 12528 12544 12560 On my server, I have PHP 4.3.11 (cgi) (built: Nov 8 2005 06:24:40) -- but I expect it's not the only version with this problem. ---- Server IP: 193.226.19.70 Probable Submitter: 81.181.249.130 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/70348 Del: integrated -- https://master.php.net/note/delete/70348/integrated Del: useless -- https://master.php.net/note/delete/70348/useless Del: bad code -- https://master.php.net/note/delete/70348/bad+code Del: spam -- https://master.php.net/note/delete/70348/spam Del: non-english -- https://master.php.net/note/delete/70348/non-english Del: in docs -- https://master.php.net/note/delete/70348/in+docs Del: other reasons-- https://master.php.net/note/delete/70348 Reject -- https://master.php.net/note/reject/70348 Search -- https://master.php.net/manage/user-notes.php
