When we compare $var==$var2, two variables are compared in case-sensive. When we use 'strpos()' to look for if one variable contains value of another variable, it is case-sensitive too. How could I do both things with case-insensitive?
Thanks.
how to compare strings in case-insensive
The case insensitive "brother" of strpos() is stripos():

You can compare strings insensitive of case by doing:
strtoupper($var) == strtoupper($var2)

Note that this is in PHP5; if you're still using PHP4.x, the closest would be something like
strpos(strtolower($search_in), strtolower($search_for));
Hi,
since strpos returns 0 if the string was found at the first position in the haystack you can't use e.g.
if (!strpos(...))
Use
if (strpos(...) !== false)
instead.
Alternatively you could use preg_match with the modifier i.
