I'm experiencing an issue with a regular expression in PHP, and I was hoping someone could help me out here. I am currently working on a project where I need to perform some complex pattern matching and extraction using regular expressions. However, I keep getting a warning that my regular expression is too large.
I have a string that contains a large amount of data, and I am trying to extract specific patterns from it using preg_match_all function in PHP. The regular expression I am using is quite lengthy, as it contains multiple nested groups and optional sections. It looks something like this:
I have tested the regular expression with smaller strings, and it works perfectly fine. However, when I try to run it on my large data string, I receive a warning stating that the regular expression is too large.
I'm not sure why I am getting this warning and how to resolve it. Could it be related to the length of my regular expression, or is there some other limiting factor I'm not aware of?
Is there a way to overcome this issue and still extract the desired patterns from my large data string? Any suggestions or alternative approaches would be greatly appreciated.
Thank you in advance for your help!
