Question

I have this code that checks if a string is blue.
I want it to approve it regardless of whether it’s lower or upper case in any of the letters.

if( ($subcol !== 'blue') || ($subcol !== 'Blue') || ($subcol !== 'BLUE')    ) {
    $form->setError($field, "* Colour not correct, use the hint");
}

This doesn’t seem to work?
Have I structured something wrong?

Also, is there a PHP function that can be used that will just check it once for all these scenarios?

Thanks

You can use:

if (strcasecmp($subcol, 'blue') === 0)  {

This is true for blue BLUE Blue bLue etc.
