I have a string of the form
<something>_string_t_<digits>
How can I extract just the <digits> portion in PHP ? I need to detect the string_t first and then pull out the digits.
You want something like this:
$captures;
preg_match('/string_t_(\d+)/', $string, $captures);
do_something($captures[1]);
$captures[1] will contain <digits> (assuming <digits> is composed entirely of numbers - if it's not, use the more general (.+) in place of (\d+)).

I know there are tons of questions about regex string format, but I am very new to this and I haven't been able to do it myself. How can I use regex to match a string with the following format?
xx_x_a.zip
where x is a number and a is a letter. Example:
33_2_f.zip
It must not match:
33_2_f_abc.zip
The format must always be like 2digits+_+1digit+_+1letter+.zip
Simplest way:
/^[0-9]{2}_[0-9]_[a-z]\.zip$/

I am trying to get string through input box from user
user can add only numbers in the string the format of a string is like this
Example
123456,111111,122335
123456 111111 122335
only "," or " " are allowed after 6 digits of number like show in example
You can use
^(?:(?:\d{6},)*|(?:\d{6}\s+)*)\d{6}$
Regex Demo
This regexp is for 3 groups of 6 digits:
\d{6}(?: |,)\d{6}(?: |,)\d{6}
You can test it here.

I need the regular expression to replace using following rule:
Any integer present before . then no take place.
If no integer present before . then that should be replace.
$input = (contain anything characters, symbols, numbers, floats etc)
Example:
$myString = "Example 1.58 Stack.68";
Output should be
Example 1.58 Stack,68
preg_replace('#(?<!\d)\.#',',',$myString)

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]*?%%/
