grep with -f like in PHP

Question

Is there such a function in PHP that does grep -f filename in unix/linux systems. If there is none, what PHP functions/tools would help in creating a customised method/funct

Answer 1

You can combine the file_get_contens() function to open a file and the preg_match_all() function to capture contents using a regex.

$file = file_get_contents ('path/to/file.ext');
preg_match_all ('regex_pattern_here', $file, $matches);
print_r ($matches);
