note 98719 added to function.unset

further I realized that an object, when getting detroyed, does care about destroying variable in object space visibility but not those in local visibility, be aware of the found pattern: class release_test{ private $buffer; private $other_object; public function __construct(){ $this->other_object=new other_object_class(); } public function __destruct(){ //note that you always have to unset class objects, in order to get the resources released unset($this->other_object); } public allocate_mem_A(){ $this->buffer=file("/tmp/bigfile"); } public allocate_mem_B(){ $buffer=file("/tmp/bigfile"); } public allocate_mem_C(){ $buffer=file("/tmp/bigfile"); unset($buffer); } public allocate_mem_D(){ $this->other_buffer=file("/tmp/bigfile"); } } //this does not lead to a resource problem $A=new release_test(); $A->allocate_mem_A(); $A->__destruct(); unset($A); //this DOES lead to a resource problem $B=new release_test(); $B->allocate_mem_B(); $B->__destruct(); unset($B); //this does not lead to a resource problem $C=new release_test(); $C->allocate_mem_C(); $C->__destruct(); unset($C); //this does not lead to a resource problem $D=new release_test(); $D->allocate_mem_D(); $D->__destruct(); unset($D); ---- Server IP: 192.35.244.50 Probable Submitter: 90.146.133.211 ---- Manual Page -- http://www.php.net/manual/en/function.unset.php Edit -- https://master.php.net/note/edit/98719 Del: integrated -- https://master.php.net/note/delete/98719/integrated Del: useless -- https://master.php.net/note/delete/98719/useless Del: bad code -- https://master.php.net/note/delete/98719/bad+code Del: spam -- https://master.php.net/note/delete/98719/spam Del: non-english -- https://master.php.net/note/delete/98719/non-english Del: in docs -- https://master.php.net/note/delete/98719/in+docs Del: other reasons-- https://master.php.net/note/delete/98719 Reject -- https://master.php.net/note/reject/98719 Search -- https://master.php.net/manage/user-notes.php
