preg_replace for 20% in url

[westman 10]

hi all i have been trying for 7 hours now and i can not find the best way to change 20% from a url string to a space.

I am trying to change this "20%" to this " ".

this is what i have....

$new_url = preg_replace('"20%"', '" "', $new_url); 

any help?

try '/[20%]+/'

so...

 

$new_url = preg_replace(''/[20%]+/', '" "', $new_url);

or

$new_url = preg_replace(''/[20%]+/', ' ', $new_url);

or

$new_url = preg_replace(''/[20%]+/', " ", $new_url);

?

Try: $new_url = preg_replace('/[20%]+/', ' ', $new_url);

Are you sure you don't mean %20? That's the escape code for the space character in URLs.

 

There's no need for a regular expression here. Use str_replace

$new_url = str_replace('%20', ' ', $new_url);

Try: $new_url = preg_replace('/[20%]+/', ' ', $new_url);

This would cause the program to replace any sequence of any length that contains 2, 0, and % with a space. It would match things like "2%02" and "%%%"

Yes. I was thinking since a URL can contain many %20, that would be ideal (to add the character class [] ) but upon further observation it would also remove the 20 from a URL like mypage20.php for example and that's not good. So for the sake of understanding, would have this been the correct way?:

 

$new_url = preg_replace('/%20/', ' ', $new_url);

 

Thanks

Yes, that would be correct. Since there are no real rules a regular expression isn't needed, you're just trying to match a literal string here.
