note 109292 added to function.is-int

I ran a benchmark for testing "is_int()"-like: $v=array("q1","q2","1","2",1,2); $s=microtime(true); for($i=0;$i<10000000;$i++){ $x=$v[$i%count($v)]; /** compare **/ } echo "total: ",microtime(true)-$s, "ms", PHP_EOL; If you'll never have testing zero-values, you can this fastest method: $x=(int)$x; isset($v); total: 6.97873ms But I depricate it! Otherwise, you should use this trick: (int)$x==$x; total: 7.27195ms (not $x==(int)$x) Then, I obtained: is_int($x); total: 7.61134ms is_numeric($x); total: 7.79037ms ---- Server IP: 195.221.21.36 Probable Submitter: 83.156.236.170 ---- Manual Page -- http://www.php.net/manual/en/function.is-int.php Edit -- https://master.php.net/note/edit/109292 Del: integrated -- https://master.php.net/note/delete/109292/integrated Del: useless -- https://master.php.net/note/delete/109292/useless Del: bad code -- https://master.php.net/note/delete/109292/bad+code Del: spam -- https://master.php.net/note/delete/109292/spam Del: non-english -- https://master.php.net/note/delete/109292/non-english Del: in docs -- https://master.php.net/note/delete/109292/in+docs Del: other reasons-- https://master.php.net/note/delete/109292 Reject -- https://master.php.net/note/reject/109292 Search -- https://master.php.net/manage/user-notes.php
