Question

For seo purposes, I was instructed to change a line of code from something like

http://www.Domain.com/Jimmy_Smith

to

http://www.domain.com/jimmy_smith

What is the line of code that will detect if there is at least 1 uppercase letter in the url?

…for seo consistency. I know regex is probably the most efficient way to do this, but I’m not very experienced with Regex.

Answer 1

if (preg_match('/[A-Z]/', $url)) {
    ... has one upper case char ...
} else {
    ... no uppercase chars at all ...
}
