regex      lt code gt       lt  code gt       Using   as the delimiter instead of   because then we don t need to escape the   in  lt  code gt   As Phoenix posted below      is used to make the      anything   match as few characters as possible before it comes across a  lt  code gt   known as a  non-greedy quantifier    That way  if your string is   lt code gt hello lt  code gt  something  lt code gt again lt  code gt    you ll match hello and again instead of just matching hello lt  code gt  something  lt code gt again

You can also try   function getTagValue  string   tag         pattern      lt   tag  gt       lt     tag  gt  s       preg match  pattern   string   matches       return isset  matches 1      matches 1            It returns empty string in case of no match

You can use the following    regex      lt  s  code b   gt    gt       lt  code b   gt    gt  s       b ensures that a typo  like  lt codeS gt   is not captured  The first pattern    gt    captures the content of a tag with attributes  eg a class   Finally  the flag s capture content with newlines    See the result here   http   lumadis be regex test regex php id 1081
