If you've got a regular

As I said, at the end of the day, this will be a manual slow, potentially wrong
implementation of what we already have and use on daily basis.

Thanks to everyone who has responded. After reading everyone's
response, I think I have a very simple way to solve my "problem".
Using my original example, if someone wants to find item #
4D-2448-7PS, no matter what they type in, I'll take the input, strip
out all non-alphanumeric charac

Ben, it does not matter, this is not a PHP problem but a DB
structure/select/insert/update problem.
Whatever REGEXP you use, a REGEXP is what you need to solve this problem,
certainly not a PHP loop over each row with operations for each row

That works if you know the user is always going to enter the last 7
characters of the product

Even if the REGEXP has to change with every query

Which DB?
If it is MySQL, as example, you can simply use REGEXP syntax "^[a-zA-Z0-9]+$"
via SELECT

Not sure i
Hi,
It's definitely possible to do when you do it in PHP, but not sure about on
the database side. You could read all records into memory and then iterate
over it with something like:
$toSearch = "4D24487PS"
$charsToIgnore = array('-','+',...);
foreach ($items as $k=>$item) {
$itemVal = str_re
25 matches
