either the benchmark I used, or the one used in an earlier comment is flawed, or this function has seen great improvement... on my system (a Duron 1GHz box) the following benchmark script gave me pretty close to 1 second execution time average when used with 355000 runs of in_array() (10 runs) <?php $average = 0; for ($run=0;$run<10;++$run) { $test_with=array( 1=>array(explode(":", ":1:2:3:4:5:6:7:8:9:10:11:12:13:14:15:")), 2=>array(explode(":", ":21:22:23:24:25:26:27:28:29:210:211:212:213:214:215:")), 3=>array(explode(":", ":14:15:23:24:25:26:27:28:29:210:211:212:213:214:215:")) ); $start = microtime(); for($i=0;$i<=355000;++$i) { in_array($i, $test_with); } $end = microtime(); $start = explode(" ",$start); $end = explode(" ",$end); $start = $start[1].trim($start[0],'0'); $end = $end[1].trim($end[0],'0'); $time = $end - $start; $average += $time; echo "run $run: $time<br>"; } $average /= 10; echo "average: $average"; ?> ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+34934 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+34934&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+34934&report=yes
