#29637 [Opn->Bgs]: fwrite needs pass by reference for string

ID: 29637 Updated by: derick@php.net Reported By: pearcec at poss dot com -Status: Open +Status: Bogus Bug Type: Zend Engine 2 problem Operating System: any PHP Version: 5.0.0 New Comment: That is not true, PHP does not copy the data in this case. PHP does a copy on write, and because the fwrite function does not change the string nothing will be copied (it's actually more efficient then passing by reference in this case). Previous Comments: ------------------------------------------------------------------------ [2004-08-12 18:52:44] pearcec at poss dot com Description: ------------ It would be great to pass the string by reference in fwrite. Otherwise it makes a copy of the data. This is a problem for very large files. PHP Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of fwrite(). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. in /home/pearcec/saturn/www/include/file/cnFileBlob.inc on line 156 Reproduce code: --------------- fwrite($fp, $inContents); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29637&edit=1
