I changed the Permalink on WP to get any strings after the path. I use the regex: "yourdomain.com/%postname%-(.*)/"
When I am checking: "yourdomain.com/%postname%-f46eb54b99ce3a9835ea7d63e075d434", it matches.
But when I check:
"yourdomain.com/%postname%-446eb54b99ce3a9835ea7d63e075d434" then it returns "yourdomain.com/%postname%-(.*)/446/".
I think (. *) Will fit in everything, regardless of letters or numbers. I appreciate anyone who can explain it to me.
You should escape all / and ., if you mean them as normal symbols. So, you'll have:
yourdomain\.com\/%postname%-(.*)\/
It must not match
yourdomain.com/%postname%-f46eb54b99ce3a9835ea7d63e075d434
or
yourdomain.com/%postname%-446eb54b99ce3a9835ea7d63e075d434
, because you regex demands / at the end. If it is not obligatory, put ? after the ending \/.
yourdomain\.com\/%postname%-(.*)\/?

This is a page URL and the :id param changes based on the resource and the query string can be all over the map.
How can I match /foo/:id/bar?anything
thanks in advance
It would help to specify any restrictions on :id as you indicated it could change.
Taken at the most direct meaning of the question, the regex
\/foo\/:id\/bar\?.*
will match the exact string /foo/:id/bar? and then anything after.
Explanation:
String matching for the first part, escaping special characters (forward slashes and question mark) with a backslash. A period . indicates any character and an asterisk * indicates any amount of the previous character so .* means match any amount of any character.

I need to remove this string
page=x
x being a dynamic string (should be a number but can be anything)
from another string, for example
url/?filter=value&page=2&filter2=value
but it can also be:
url/?page=2
So, these are the cases as examples
1. url/?page=2&filter=value
2. url/?page=2
3. url/?filter=value&page=2
4. url/?filter=value&page=2&filter2=value
And they should return:
1. url/?filter=value
2. url/
3. url/?filter=value
4. url/?filter=value&filter2=value
How can I do that with regex?
You've said:
[?&]page=[^&]+
works for you. This will look for an ? or & then page= and anything after it until an &. A bit longer answer though is:
echo rtrim(preg_replace('/([?&])page=[^&]*&?/', '$1', $string), '&?')
which will correctly handle the intro and ending parameter cases.

I have a string mystring. I have to replace the alternate characters with x so that final output is mxsxrxnx. All the alternate characters starting from 2nd position are replaced with x. I can do it with loop but is there a Regular expression for that or a better way in PHP? Please help.
Using a reset match meta-character \K you are able to do it:
.\K.
Live demo
PHP:
echo preg_replace('/.\K./', 'x', 'mystring'); // mxsxrxnx

I have link .
http://www.example.com/about
$_SERVER['REQUEST_URI'] is /about.
So when I do
preg_match("/about/i",$_SERVER['REQUEST_URI']),
it matches the about link.
But if I have to match www.example.com, then I saw that $_SERVER['REQUEST_URI'] returns /.
So I used this code
preg_match("/\//i",$_SERVER['REQUEST_URI']),
but it dosent work. Why?What is the correct solution to preg match /?
You are looking in the wrong variable. $SERVER['REQUEST_URI'] only gives you the relative name of the request, so in your example you will only get "/about". To get the domain name, use the superglobal $SERVER['SERVER_NAME'];.

I have the following regex:
/%%[\s\S]*?%%/i
It's meant to catch these types of strings:
%%test%%
%%test2%%
However, because this regex runs on big strings, sometimes there are mistakes, for example if i have this:
%test%% adhja kshdjah skdja %%test1%% it will return %% adhja kshdjah skdja %%
The strings that it is supposed to catch never have any spaces in them, how can I alter my regex to take only the ones with no spaces?
Use [^%\s] for non space and non %.
/%%[^%\s]*?%%/
