preg_replace for multidimensional arrays

Anybody trying to use preg_replace on multidimensional arrays will see that the function is not working for those cases. Here a quick workaround:

    

  1. 
function preg_replace_array($pattern, $replacement, $subject, $limit=-1) {

    2. 

  2.     if (is_array($subject)) {

    3. 

  3.         foreach ($subject as &$value) $value=preg_replace_array($pattern, $replacement, $value, $limit);

    4. 

  4.         return $subject;

    5. 

  5.     } else {

    6. 

  6.         return preg_replace($pattern, $replacement, $subject, $limit);

    7. 

  7.     } 
    8. 

  8. }
    9.

 

Enjoy coding …

I am a full-stack developer. I love programming,  design and know my way around server architecture as well.  I would never feel complete, with one of these missing. I have a broad range of interests, that’s why I constantly dive into new technologies and expand my knowledge where ever required. Technologies are evolving fast and I enjoy using the latest. Apart from that, I am a peace loving guy who tries to have people around him that think the same.  I truly believe in the principle: “If you help someone, someone will help you, when you need it."
