Question

I need to create an IF clause that would catch all strings that are in the following format:

Pharm followed by any letter followed by any three digits.

For example, Pharmf750 or Pharmc648

Thanks for your help.

Answer 1

The regex you need is /^Pharm[A-Za-z][0-9]{3}$/.

Try something like

if (preg_match('/^Pharm[A-Za-z][0-9]{3}$/', $stringToMatch) {
    // Do something
}
