Many examples are – but still a stumbling block in my mind.
I need to extract first number 21538 from links like
$input_line ='https://ex.com/prom-nt/21538-asus-screen17.html'
using PHP preg_replace like
preg_replace('/(^\D+)(.*)-(.*)/', '\2', $input_line);
I get output
21538-asus
using PHP preg_replace like
preg_replace('/(^\D+)(.*)[0-9]-(.*)/', '\2', $input_line);)
I lose last digit (8) and get output
2153
not 21538 – so a solution is somewhere near but can’t catch it.
Thx in advance for any hint to try,
>Solution :
you should move [0-9] into to the capture part. I mean this:
preg_replace('/(^\D+)(.*[0-9])-(.*)/', '\2', $input_line);
