preg_replace

[leam hall]

Despite my best efforts to ignore preg_replace, it seems the best answer
for the current problem. That is, if I can get it to work...

Problem code:

$remove = "TAG000000-";
$replaceWith = "";
$newTitle = preg_replace($remove, $replaceWith, $title);

This, as well as using the $remove and $replaceWith as themselves and not
variables, gives:

PHP Warning: preg_replace(): Delimiter must not be alphanumeric or
backslash

Thoughts?

Hi,

Despite my best efforts to ignore preg_replace...

Why? :)

backslash
Thoughts?

You are just using it wrong.

uhh....okay, I feel mildly silly...especially since I use delimiters with
sed...

Adam, thanks!

If you only want to replace the string 'TAG000000-', you can just use
'str_replace()' (no need to use regular expression).

If you DO want to use regular expression (with preg_replace()), then you
need to understand regular expressions first:

Can you offer a working example of the actual data you are working with and
what you expect to happen? Besides preg_replace, what have you tried and what
didn't work as expected?

Hey Jim,

The problem was tags. Most items had a tag "TAG00001", "TAG00002", etc.
Some had "TAG00000-SPECIAL001", "TAG000000-SPECIAL002". I was looking to
remove the "TAG00000-" bits. Using str_replace should take care of it.

Thanks!

Leam
