php string function to get substring before the last occurrence of a character

Question

$string = "Hello World Again".
echo strrchr($string , ' '); // Gets ' Again'

Now I want to get "Hello World" from the $string [The substring before the last occurrence of a space ' ' ]. How do I get it??

Answer 1

$string = "Hello World Again";
echo substr($string, 0, strrpos( $string, ' ') ); //Hello World

If the character isn't found, nothing is echoed
