Hi I am trying to create regex expression and I am running into problems.

Basically this is what I have:

(.+?)(and|or)(.+?)

What I

Answer 1

Try this, but I used explode() method in PHP and not Regex.
The input should have every user on a line, and without parenthesis (you can modify the code to remove the parenthesis), but at least this is the concept.

";

//final array
$result = array();

//separate each line as element in an array
$line = explode("\n",$string);

//iterate through each line
for($k=0; $k 1){
            $and[] = array();
            $lastId = count($and)-1;
            for($j=1; $j

Output:

Array
(
    [0] => Array
        (
            [0] => user email ends with "@domain.com" 
            [1] =>  user name is "Bob" or user id is 5
            [2] => Array
                (
                    [0] =>  user id is 5
                )

        )

    [1] => Array
        (
            [0] => user email ends with "@domain.com" 
            [1] =>  user name is "Bob" or user id is 5
            [2] => Array
                (
                    [0] =>  user id is 5
                )

        )
