Adding Values in a string


Recommended Posts



I currently have a string with some values in it:


$a_random_string="some random text, goes here - $123<br>some more random text goes here - $53 (text 123 )<br>ANother line of text - $126";


Now I want to add all the values that have a '$' before the value eg; $123.


So in this case I would end up with: 302


How would I do this?

Thank you for your reply,


Basically I have a string of variable data in it and I want to add up all the numeric values in the string that have the $ character in front of the number. However I do not want the numbers with the $ character before the number to be added.




blabla 621.

- Dont include this


more text $63. with some more text 12.

- Include the number 63 but not the number 12


Hope that helps.

Hey mme, have a look at the following...


  // String to get values from
  $startString = 'some random text, goes here - $123<br>some more random text goes here - $53 (text 123 )<br>ANother line of text - $126';
  // Add | to all values that begin with $ and contain numbers
  $string = preg_replace('/(\$[0-9]{1,})/','|$1|',$startString);
  // Explode |
  $string = explode('|',$string);
  // Count Length of exploded string
  $count  = count($string);

  // Preg match for any values not contain a space
  // If no space is found, it must be a number beginning with $
  // Replace $ and then add the values up
  for($i=0; $i<$count; $i++) {
    if(!preg_match("/ /i", $string[$i])) {
      $result += str_replace('$','',$string[$i]);

  // Echo resulting value
  echo $result;


Tell me if it works out for you bud :)


Regards, Paul.
