How to compare between two values
You may also use strcmp() to compare string values:
if (strcmp($string1, $string2) == 0) {
//do stuff
}
I know that in ASP (*gasp*... he uses a MS technology!) the StrComp function has an increased performance difference over comparing the strings with an equals sign. I do not know whether this is also the case in PHP. But, nonetheless, it's just another way of doing things.
Again, check the documentation. This one can be found at:
