note 98821 added to function.count

To test if an array is empty, prefer use empty than count==0. Look this stats : Expression : $a= array(); //Key legend 0 for if(empty($a)) 1 for if(count($a) == 0) 2 for if(count($a) === 0) 3 for if(!count($a)) For 1000 iterations : Test #1 : Array ( [0] => 0.0190088748932 [1] => 0.0262041091919 [2] => 0.0264089107513 [3] => 0.0246360301971 ) Test #2 : Array ( [0] => 0.0191049575806 [1] => 0.0265319347382 [2] => 0.0264468193054 [3] => 0.0246489048004 ) Test #3 : Array ( [0] => 0.01922082901 [1] => 0.0262050628662 [2] => 0.0264029502869 [3] => 0.024729013443 ) Test #4 : Array ( [0] => 0.0191278457642 [1] => 0.0262858867645 [2] => 0.0264329910278 [3] => 0.0247249603271 ) Test #5 : Array ( [0] => 0.0190749168396 [1] => 0.0263991355896 [2] => 0.0263121128082 [3] => 0.0247128009796 ) Test #6 : Array ( [0] => 0.0191838741302 [1] => 0.0262401103973 [2] => 0.0264360904694 [3] => 0.0245780944824 ) Test #7 : Array ( [0] => 0.0192511081696 [1] => 0.0262877941132 [2] => 0.026477098465 [3] => 0.0244669914246 ) Test #8 : Array ( [0] => 0.0190861225128 [1] => 0.0263922214508 [2] => 0.0263969898224 [3] => 0.0246238708496 ) Test #9 : Array ( [0] => 0.0191929340363 [1] => 0.0262160301208 [2] => 0.026976108551 [3] => 0.0244481563568 ) Test #10 : Array ( [0] => 0.019070148468 [1] => 0.0260848999023 [2] => 0.0262608528137 [3] => 0.0245189666748 ) Average : empty use 0.0191xxx for 1000 iterations count use 0.026xxxx (in best case 0.024xxxx) for 1000 iterations ---- Server IP: 195.221.21.36 Probable Submitter: 85.116.42.193 ---- Manual Page -- http://www.php.net/manual/en/function.count.php Edit -- https://master.php.net/note/edit/98821 Del: integrated -- https://master.php.net/note/delete/98821/integrated Del: useless -- https://master.php.net/note/delete/98821/useless Del: bad code -- https://master.php.net/note/delete/98821/bad+code Del: spam -- https://master.php.net/note/delete/98821/spam Del: non-english -- https://master.php.net/note/delete/98821/non-english Del: in docs -- https://master.php.net/note/delete/98821/in+docs Del: other reasons-- https://master.php.net/note/delete/98821 Reject -- https://master.php.net/note/reject/98821 Search -- https://master.php.net/manage/user-notes.php
