从URL中删除特殊字符

Question

I have a product database and I am displaying trying to display them as clean URLs, below is example product names:

PAUL MITCHELL FOAMING POMADE (150ml)
American Crew Classic Gents Pomade 85g
Tigi Catwalk Texturizing Pomade 50ml

What I need to do is display like below in the URL structure:

www.example.com/products/paul-mitchell-foaming-gel(150ml)

The problem I have is I want to do the following:

1.  Remove anything inside parentheses (and the parentheses)
2.  Remove any numbers next to g or ml e.g. 400ml, 10g etc...

I have been banging my head trying different string replaces but cant get it right, I would really appreciate some help.

Cheers

Answer 1

function makeFriendly($string)
{
    $string = strtolower(trim($string));
    $string = str_replace("'", '', $string);
    $string = preg_replace('#[^a-z\-]+#', '_', $string);
    $string = preg_replace('#_{2,}#', '_', $string);
    $string = preg_replace('#_-_#', '-', $string);
    return preg_replace('#(^_+|_+$)#D', '', $string);
}

this function helps you for cleaning url. (also cleans numbers)
