How to preg_mach_all in different lines?

Question

<div class="information di-ib mt4">
    Movie (1 eps)<br>
    Aug 2016 - Aug 2016<br>
    380,496 members
</div></div>

I want to make preg_match_all in this code, but I do not know how to do in particular the number of episodes.

Answer 1

If the text has only data from a movie, you can use the function preg_match:

if (preg_match("/\((?P<qtd>\d+) eps\)/", $data, $matches))
{
  echo "O filme possui ", $matches["qtd"], " episódio(s)", PHP_EOL;
}

The output for the text in question would be:

O filme possui 1 episódio(s)

See working on Ideone.

However, if the text contains information from more than one actual film it will be necessary to use the preg_match_all:

if (preg_match_all("/\((?P<qtd>\d+) eps\)/", $data, $matches))
{
  print_r($matches["qtd"]);
}

The only difference is $matches["qtd"] will be a list of values for all films.

See working on Ideone.

The regular expression used in both cases is:

/\((?P<qtd>\d+) eps\)/

Her goal is to find all the groups in the format (X eps), being X an integer value.

1. The part \( escapes the character ( and indicates the start of the desired group;
2. The part (?P<qtd>\d+) captures any sequence of numbers, generating the named group qtd;
3. The part eps makes it necessary for the sequence of numbers to be followed by that text;
4. The part \) escapes the character ) and indicates the end of the desired group;

Answer 2

Using preg_match_all:

<?php
$dado = "
<div class='information di-ib mt4'>
    Movie (1 eps)<br>
    Aug 2016 - Aug 2016<br>
    380,496 members
</div>";
preg_match_all("/(?<=\()[\d]/",$dado,$saida,PREG_PATTERN_ORDER);
print_r($saida[0]);//Array ( [0] => 1 )
?>
