Extract Characters Before And After Middle Symbol regex and rest string

Question

I have a file name like this

1x5 Girl In The Flower Dress.mkv

It means Season 1 Episode 5 of In The Flower Dress

2x6.English,.Fitz.or.Percy.avi

It means Season 2 Episode 6 of English, Fitz or Percy

How to extract Season number ,Episode number and series name

Answer 1

Input

2x6.English,.Fitz.or.Percy.avi

Try this:

preg_match("/(\d*)x(\d*).?(.*)\.(.*)/", $input, $output_array);

output_array

array(
  0 =>  2x6.English,.Fitz.or.Percy.avi
  1 =>  2   // Season 
  2 =>  6   // Episode
  3 =>  English,.Fitz.or.Percy  // title
  4 =>  avi
 )

Answer 2

How about a more direct solution?

$title = '2x6.English,.Fitz.or.Percy.avi';

preg_match_all('~(?:(\d+)x(\d+)|(?!^)\G)[^\w\r\n,-]*\K[\w,-]++(?!$)~m', $title, $matches);
$matches = array_map('array_filter', $matches);

echo "Season {$matches[1][0]} Episode {$matches[2][0]} of ".implode(' ', $matches[0]);

Output:

Season 2 Episode 6 of English, Fitz or Percy

Answer 3

At first, I wanted to write: $out=preg_split('/[\\. x]/',$in,3,PREG_SPLIT_NO_EMPTY); but because the title words can be dot delimited AND you don't want to capture the file suffix, I had to bin that method.

Barmar's method includes the file suffix, so that will require additional handling. Ravi's pattern isn't as refined as it could be.

Revo's method is inspired, but requires 4x as many steps as my pattern. Regex Demo Both of our methods require an additional function call to prepare the title. I find my method to be very direct and doesn't require any array filtering.

$input[]='1x5 Girl In The Flower Dress.mkv';
$input[]='2x6.English,.Fitz.or.Percy.avi';

foreach($input as $in){
    preg_match('/(\d+)x(\d+)[ \.](.+)\..+/',$in,$out);
    echo "<div>";
        echo "Season $out[1] Episode $out[2] of ",str_replace('.',' ',$out[3]);
    echo "</div>";
}

Output:

Season 1 Episode 5 of Girl In The Flower Dress
Season 2 Episode 6 of English, Fitz or Percy

Answer 4

Use capture groups to get the parts of the string that match parts of the pattern.

preg_match('/(\d+)x(\d+)\s*(.*)/', '1x5 Girl In The Flower Dress.mkv', $match);

$match[1] will be '1' , $match[2] will be '5' , and $match[3] will be 'Girl in the Flower Dress.mov' .

You need to use \\d+ to match more than one digit in the season or episode number.
