$arr -> array of files, for us it was file1.log and file2.log,
dont forget to write the filename without extension, since its
handled in "$file      = "./__logs/" . $value . ".log";" so just
replace that extension .log to any you need, like .txt or .sql

//set_time_limit(0); -> Needed if you searching in big files for long time
