get everything between <tag> and </tag> with php [duplicate]

Question

I'm trying to grab a string within a string using regex.

I've looked and looked but I can't seem to get any of the examples I have to work.

I need to grab the html tags <code> and </code> and everything in between them.

Then I need to pull the matched string from the parent string, do operations on both,

then put the matched string back into the parent string.

Here's my code:

$content = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. <code>Donec sed erat vel diam ultricies commodo. Nunc venenatis tellus eu quam suscipit quis fermentum dolor vehicula.</code>" $regex=''; $code = preg_match($regex, $text, $matches); 

I've already tried these without success:

$regex = "/<code\s*(.*)\>(.*)<\/code>/"; $regex = "/<code>(.*)<\/code>/"; 

Answer 1

You can use the following:

$regex = '#<\s*?code\b[^>]*>(.*?)</code\b[^>]*>#s'; 

• \b ensures that a typo (like <codeS>) is not captured.
• The first pattern [^>]* captures the content of a tag with attributes (eg a class).
• Finally, the flag s capture content with newlines.

this function worked for me

<?php  function everything_in_tags($string, $tagname) {     $pattern = "#<\s*?$tagname\b[^>]*>(.*?)</$tagname\b[^>]*>#s";     preg_match($pattern, $string, $matches);     return $matches[1]; }  ?>
