How to get a substring between two strings in PHP?

Answer 1

Not a php pro. but i recently ran into this wall too and this is what i came up with.

function tag_contents($string, $tag_open, $tag_close){
   foreach (explode($tag_open, $string) as $key => $value) {
       if(strpos($value, $tag_close) !== FALSE){
            $result[] = substr($value, 0, strpos($value, $tag_close));;
       }
   }
   return $result;
}

$string = "i love cute animals, like [animal]cat[/animal],
           [animal]dog[/animal] and [animal]panda[/animal]!!!";

echo "
";
print_r(tag_contents($string , "[animal]" , "[/animal]"));
echo "
";

//result
Array
(
    [0] => cat
    [1] => dog
    [2] => panda
)
