PHP在一个输入中分隔两个不同的部分

Question

I'm working on a PHP based application extension that will extend a launcher style app via the TVRage API class to return results to a user wherever they may be. This is done via Alfred App (alfredapp.com).

I would like to add the ability to include show name followed by S##E##: example: Mike & Molly S01E02

The show name can change, so I can't stop it there, but I want to separate the S##E## from the show name. This will allow me to use that information to continue the search via the API. Even better, if there was a way to grab the numbers, and only the numbers between the S and the E (in the example 01) and the numbers after E (in the example 02) that would be perfect.

I was thinking the best function is strpos but after looking closer that searches for a string within a string. I believe I would need to use a regex to correctly do this. That would leave me with preg_match. Which led me to:

$regex = ?;
preg_match( ,$input);

Problem is I just don't understand Regular Expressions well enough to write it. What regular expression could be used to separate the show name from the S##E## or get just the two separate numbers?

Also, if you have a good place to teach regular expressions, that would be fantastic.

Thanks!

Regex:

$text = 'Mike & Molly S01E02';
preg_match("/(.+)(S\d{2}E\d{2})/", $text, $output);
print_r($output);

Output:

Array
(
    [0] => Mike & Molly S01E02
    [1] => Mike & Molly 
    [2] => S01E02
)

If you want the digits separately:

$text = 'Mike & Molly S01E02';
preg_match("/(.+)S(\d{2})E(\d{2})/", $text, $output);
print_r($output);

Output:

Array
(
    [0] => Mike & Molly S01E02
    [1] => Mike & Molly 
    [2] => 01
    [3] => 02
)

Explanation:

. --> Match every character

.+ --> Match every character one or more times

\d --> Match a digit

\d{2} --> Match 2 digits

The parenthesis are to group the results.
