I am writing a script that needs to download images related to a product ID array to an external website. Here are the possible product ID combinations.
I need to be able to convert them to their URL equivalent on the manufacturer's website, which are (In the same order):
I am looking for a Regex to use with preg_replace that would do the trick. Thanks in advance!
$output = strtolower(preg_replace('~\d\K(?=[A-Z])|-~', '_', $input));
\K removes that is matched on the left from the match result, so , the digit before the letter is not a part of the match and will not be replaced.
(?=...) is a lookahead assertion that checks if a letter if following, it isn't a part of the match result too and will not be replaced too.
I'm a noob in regular expressions but I`ll give it a shot.
Input: /([A-Z]+)\d+([A-Z]+)\-([A-Z]+)/
A-Z matches uppercase alpha characters \d matches numbers
"+" is used to repeat
And in the replacement callback use strtolower on the matches and join them how you want :P
