déc. there is a function dedicated for just this purpose, preg_grep . it will take a regular expression as first parameter, and an array as the second. see the below example: $haystack = array ( 'say hello', 'hello stackoverflow', 'hello world', 'foo bar bas' ); $matches = preg_grep ('/^hello (\w)/i', $haystack); print_r  $names = preg_grep("/mt\d{}./", $array);. match 'mt' followed by digits followed by '' followed by zero or more of any characters. you can play with this a little easier using a tool like regexr, heres a link with your example: regexr?irf. so i'm currently using preg_grep to find lines containing string, but if a line contains special chars such as " . " i can simply type letter that is within that line and it will output as a php preggrep. asked dec ' at :. user. . . votes. answer. views  you could use this kind of function, using string.matches() and iterating over your array : public static list preg_grep(string pattern, list array) { list indexes = new arraylist(); int index = ; for (string item : array) { if (item.matches("ba.")) { indexes.add(index); } index; } return indexes; }.
