Get substring within string

[tmh766]

How is it possible to search a string, find a start character and save all the characters after the start character into a variable untill an ending character is found?

 

I know its something like this...

 

$startPlace=strpos($content,"start string");

 

But I dont know a way to save the content after the start character untill and ending character is found...

$sub = substr($string, strpos($string, 'search'));
