please ignore my previous comment, i'm dumb... should be checking for false, as
zero is a valid offset.

strpos has a bug.
the following statement should give 1, but gives zero:
echo strpos(strtolower('C'), 'c');

Sorry, but it works correct.
In your sample $query has no "insert", therefore strpos
returns 0 (not found), as desribed in the manual.

Thats the documented and expected behaviour.

<?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.
