Let say I have a string like this
sometext<br>sometext<br>sometext(Rating 50)<br>sometext<br>
All I want to get from this string is the "50" right after the "Rating". The number can range from 1 to 3 digits long.
Can I use something like preg_replace? explode? not sure how to get it.
$str = "sometext<br>sometext<br>sometext(Rating 50)<br>sometext<br>";
preg_match('/\(Rating (\d+)\)/',$str, $matches);
echo $matches[1];
You can use explode to get individual components and then search for "Rating". Then 50 will be the element after "Rating". Of course, if you are going to use similar routine frequently, it's better to make a helper function that you could use repeatedly.
But be aware that, this will only work for the first occurrence of the string you are looking for.
Perhaps, there is an elegant solution involving Regular Expressions as opposed to creating an intermediate array and looping.
preg_replace('/\(Rating (\d+)\)/','$1',$thestring);
