Edit Text File

[millercj]

Hi i'm looking for some guidance on a how-to if this is possible.

 

I want to edit a text file at specific points such as let say this is my file:

Hello: 5
Goodbye: 3

 

I know how to get the values (5 and 3) by using pregmatch() but is there a way that (using some sort of If statement) if a condition is true, Increment a value and return/save it to the respective tag (Hello or Goodbye)

<?php
  $text = 'Hello: 5
Goodbye: 3';
  $text = preg_replace('/(Hello\:\s+)(\d+)/e','"$1".($2+1)',$text);
  print $text;
?>
