PHP Help Needed (easy q for programmers)

[Emil]

I want to compare 2 strings but it shouldn't matter if the strings are uppercase or lowercase. Can anyone show me what the code would look like?

[tnaindex]

if (strtolower($string1)==strtolower($string2))
{
Thank_me();
}

if (strtolower($string1)==strtolower($string2))
{
Thank_me();
}

That's one way to do it, but there's a string function for it, so if it's a operation that has to repeated many times I think there's less overhead in using:

Dispite of what you might think is indicated by the name, this function is case insencitive

if(strcasecmp($string1,$string2) == 0)
{
   Thank_me_more();
}

Returns:
* 0 - if the two strings are equal
* <0 - if string1 is less than string2
* >0 - if string1 is greater than string2
