PHP Question
Extract a particular character from a string
I want to extract the episode number from the name of TV Series.
e.g. If it is "Game of Thrones S06E01", Then I should get 01.
What I am trying is :
- First see if the string contains something like "S__E__"(e.g "Blacklist S01E05")
- If yes, then see what's there after "E" or "e", and extract it.
But due to variation in types of inputs, I can get different names to check like :
- Blacklist S01E01
- Blacklist s01e01 (small "e" and "s")
- Blacklist S1E1
- Blacklist S01E01.mkv
- Se7en S01E01
and so on...

Praise the power of regular expressions then:
\b(?i)S\d+E(\d+)(?i-)\b
In
PHP this would be:
<?php
$data = <<<DATA
Blacklist S01E01
Blacklist s01e01 (small "e" and "s")
Blacklist S01E01.mkv
Se7en S01E01
DATA;
$regex = '~\b(?i)S\d+E(\d+)(?i-)\b~';
preg_match_all($regex, $data, $matches);
print_r($matches);
?>
And see a demo on ideone.com.
Updated: To do it in
jQuery/JavaScript, you need to change the inline modifiers:
\bS[\d.]+E(\d+)\b
See a demo on regex101.com (and mind the modifiers!).
