Question

This is for analyzing a string… in need to explode a string to get all chars. Basically:

$string = "This is (1990-2002) some, text [after] this.";

What do i need to do to get this:

$string = "This is ( 1990 - 2002 ) some , text [ after ] this .";

This can be something like:

$string = str_replace('','',$string);

Note: It is not a problem if double spaces get inserted ill remove it…

try this:

$string = "This is (1990-2002) some, text [after] this.";
$pattern = '/([^a-zA-Z0-9])/';
$replace_pattern = ' $1 ';
echo preg_replace($pattern, $replace_pattern, $string);
