Re^3: what is the best way to seperate the digits and strings from variable ?by polettix (Vicar)

Please read the OP and the variable names in the test code before slapping hands. You can be right from your implied point of view, but I had my rationale when posting (which implies that I tested my code, of course)
Here, I'm considering digits as a character class, not as components of a number whose semantic is different from that of a string; this is why I name my variable $start_digits, not $num as you do. As you've surely noted, the OP never talks about numbers, always about digits (anyway, as I noted in my post, the OP was not clear about the usage of this extracted data).
Thus, when I thought about putting "*" or "+"*, I considered that if there were no digits it was good, and the returned string would be empty.
I think you can agree with me that, had the OP asked for initial letters, the regex:
would do the job.
*I swear I thought about that!
