Split String into Parts PHP

Have the following string i need to split.

$string = "This is string sample - $2565";
$split_point = " - ";

One: I need to be able to split the string into two parts using a regex or any other match and specify where is going to split.

Second: Also want to do a preg_match for $ and then only grab number on the right of $.

Any suggestions?

From stackoverflow

• $split_string = explode($split_point, $string);
  

  and

  preg_match('/\$(\d*)/', $split_string[1], $matches);
  $amount = $matches[1];
  

  If you want, this could all be done in one regex with:

  $pattern = '/^(.*)'.preg_quote($split_point).'\$(\d*)$/'
  
  preg_match($pattern, $string, $matches);
  $description = $matches[1];
  $amount = $matches[2];
  

  Wimmer : Please, to avoid unexpected errors, do add preg_quote around the $split_point in the regex example.

• $parts = explode ($split_point, $string);
  /*
  $parts[0] = 'This is string sample'
  $parts[1] = '$2565'
  */
  

• Two other answers have mentioned explode(), but you can also limit the number of parts it's meant to split your source string into. For instance:

  $s = "This is - my - string.";
  list($head, $tail) = explode(' - ', $s, 2);
  echo "Head is '$head' and tail is '$tail'\n";
  

  Will given you:

  Head is 'This is' and tail is 'my - string.'
  

  Codex73 : Isn't the output: Head is 'This is-' and tail is 'my - string.' ?

  Keith Gaughan : Nope, definitely not. I even checked it in the PHP REPL before posting.

  Codex73 : so what happened to the first - ?

  Codex73 : your completely right. I forgot you exploded " - " and not "-".

  Codex73 : how will i split from the last - and not the first. can i make explode search from right to left instead?

  Keith Gaughan : There's no simple way to do that, mainly because it's not something you usually want to do. Unfortunately, the intuitive way of doing it (using a negative number) does something completely different. Try exploding the string, popping the last element, and imploding it again.

• explode is the right solution for your specific case, but preg_split is what you want if you ever need regular expressions for the separator :)
