Previous Comments: ------------------------------------------------------------------------ [2013-06-29 02:10:51] aledmb at gmail dot com strpos has a bug. the following statement should give 1, but gives zero: echo strpos(strtolower('C'), 'c'); ------------------------------------------------------------------------ [2001-12-30 10:54:04] georg@php.net Sorry, but it works correct. In your sample $query has no "insert", therefore strpos returns 0 (not found), as desribed in the manual. ------------------------------------------------------------------------ [2001-12-30 10:50:04] mfischer@php.net Thats the documented and expected behaviour. ------------------------------------------------------------------------ [2001-12-30 10:45:00] armtuk at yahoo dot com <?php $query="insert into users (user_name) values 'user_name'"; if (strpos(strtolower($query),"select")==0) { print "FISH!"; } ?> Amazingly enough this prints FISH!. but: $query="insert into users (user_name) values 'user_name'"; if (strpos(strtolower($query),"select")==0&&!(strpos(strtolower($query,"select")===FALSE)) { print "FISH!"; } does not. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=14774&edit=1
