note 60317 added to function.serialize

If you are going to serialie an object which contains references to other objects you want to serialize some time later, these references will be lost when the object is unserialized. The references can only be kept if all of your objects are serialized at once. That means: $a = new ClassA(); $b = new ClassB($a); //$b containes a reference to $a; $s1=serialize($a); $s2=serialize($b); $a=unserialize($s1); $b=unserialize($s2); now b references to an object of ClassA which is not $a. $a is another object of Class A. use this: $buf[0]=$a; $buf[1]=$b; $s=serialize($buf); $buf=unserialize($s); $a=$buf[0]; $b=$buf[1]; all references are intact. ---- Manual Page -- http://www.php.net/manual/en/function.serialize.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60317 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60317&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60317&report=yes Search -- http://master.php.net/manage/user-notes.php
