Is == in PHP a case-sensitive string comparison?

Question

I was unable to find this on php.net. Is the double equal sign (==) case sensitive when used to compare strings in PHP?

Answer 1

Yes, == is case sensitive. The easiest way for me is to convert to uppercase and then compare. In instance:

$var = "Hello";
if(strtoupper($var) == "HELLO") {
    echo "identical";
}
else {
    echo "non identical";
}

I hope it works!
