substring - PHP : how separate a string into 4 parts?

Solution:

If, for the name part, you assume there will always be at least two words, you can make a pretty naive regular expression to get it in one go:

$str = 'Bill Gates - Founder and CEO - Microsoft';
preg_match('/^(.+) (.+) - (.+) - (.+)$/', $str, $parts);

print_r($parts);

/*
Array
(
    [0] => Bill Gates - Founder and CEO - Microsoft
    [1] => Bill
    [2] => Gates
    [3] => Founder and CEO
    [4] => Microsoft
)
*/
Copy code

Or using named groups if you don't want to use array indices 1 through 4:

$str = 'Bill Gates - Founder and CEO - Microsoft';
preg_match('/^(?P<firstName>.+) (?P<lastName>.+) - (?P<position>.+) - (?P<company>.+)$/', $str, $parts);

print_r($parts);

/*
Array
(
    [firstName] => Bill
    [lastName] => Gates
    [position] => Founder and CEO
    [company] => Microsoft

// but also:
    [0] => Bill Gates - Founder and CEO - Microsoft
    [1] => Bill
    [2] => Gates
    [3] => Founder and CEO
    [4] => Microsoft
)
*/

To complete uVolpus answer:

The 'explode' is the best solution in this case, however it is important to double explode the array in order to get the first and last names.

Here is the full code:

   $str = 'Bill Gates - Founder and CEO - Microsoft';
   $array = explode(" - ", $str);
   $new_array = array();
   $new_array['full_name'] =  $full_name = $array[0];
   $new_array['first_name'] = $first_name = explode(' ',$array[0])[0];
   $new_array['last_name'] = $last_name = explode(' ',$array[0])[1];;
   $new_array['position'] = $position = $array[1];
   $new_array['company'] = $company = $array[2];

   echo "new_array"; print_r($new_array);
