    To do this, you can use the function explode
    It breaks a line into parts according to some static delimiter:

     $a = '1,2,3,4,5'; $array = explode(',', $a);

    For more complex cases there is a function preg_split
    It allows you to use a regular expression as a delimiter:

     $a = '1,2;3, 4, 5'; $array = preg_split('[,;]\s*', $a);

    For the implementation of the inverse operation (gluing a string from an array) there is a function implode

     $a = implode(', ', $array); // '1, 2, 3, 4, 5'
