note 63159 added to language.types.array

To copy values from an array which contains arrays db 05-Jan-2005 04:06 said : If you copy (=) an array which contains arrays it will be REFERENCED not COPIED. Well, this is only true since PHP 5. Under PHP4, it is COPIED. So be aware of this when porting code from PHP 4 to PHP 5 ! Now, if you want to copy the values (and not the references), (instead of using array_diff as stated below, which won't work either under PHP 5) just use : $a2 = array_combine($a1, $a1); ---- Server IP: 147.32.160.17 Probable Submitter: 82.123.17.126 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/language.types.array.php Edit -- http://master.php.net/note/edit/63159 Del: integrated -- http://master.php.net/note/delete/63159/integrated Del: useless -- http://master.php.net/note/delete/63159/useless Del: bad code -- http://master.php.net/note/delete/63159/bad+code Del: spam -- http://master.php.net/note/delete/63159/spam Del: non-english -- http://master.php.net/note/delete/63159/non-english Del: in docs -- http://master.php.net/note/delete/63159/in+docs Del: other reasons-- http://master.php.net/note/delete/63159 Reject -- http://master.php.net/note/reject/63159 Search -- http://master.php.net/manage/user-notes.php
