PHP Regex替换标签

Question

I have a piece of text that contains:

[shipping_address]
<p><b>#shipping_title#</b></p>
<p>#shipping_name#<br>
  #shipping_streetNrBox#<br>
  #shipping_zipcode# #shipping_city#<br>
  #shipping_country#<br>
</p>
[/shipping_address]

In php if a certain if statements return true, I want to remove the entire block (including [shipping_address][/shipping_address]). I am using a preg_replace but I need some help with the code.

$content = preg_replace("\[shipping_address\](.*?)\[/shipping_address\]", "" , $content);

does not do the trick, can someone help me out please.

Answer 1

This will do the stuff:

$sData = preg_replace('/\[shipping_address\](.*?)\[\/shipping_address\]/si', '', $sData);

-be aware about using pattern delimiters and multiline replacement (s modifier - in this case, it refers to . (dot) symbol). I've also added i modifier to make replacement case-insensitive.
