Hello AlliedModders community

,
I am new to AMXX scripting, but I am familiar with PHP, so I understand what most of the things are doing in AMXX scripts.
My question is regarding the "find_and_replace" function. I noticed it in GHW's icebob2 script. I see how he used it, but I'm not sure which module is required for this function.
If you could help me out that would be great!
