Get data from html (url)

Question

we want to create a script that gather data from url.

I have read a lot about this in internet, but cant manage to make it work.

The data i need to get is a key that is found on a specific url.

playlist: '/get_file.php?stream=WyJPRUU1TkRWRk5VUXpSVFJGUXpFM1FUb3hNemcxTWpFME5Ua3lMamMzTlRRNlpHWTBZV00wTUdVNU16ZzJObVZqTkdFNU9HSXdaVEptT0dGaE5XUmhaREUzTUdVd09UUTJaZz09IiwicmVnIl0=',

i need that long key that is after **stream=** and ends with

',

we saw some examples, like:

<?php
  $link = file_get_contents("http://www.domain.com");
  $file = strip_tags($link, "<div>");
  preg_match_all("/<div/>(?:[^<]*)<\/div>/is", $file, $content);
  print_r($content); 
?>

but its not our case. Please help us to get this data from url, thnx for reading.

Answer 1

$url = 'www.example.com';
$url .='/get_file.php?stream=WyJPRUU1TkRWRk5VUXpSVFJGUXpFM1FUb3hNemcxTWpFME5Ua3lMamMzTlRRNlpHWTBZV00wTUdVNU16ZzJObVZqTkdFNU9HSXdaVEptT0dGaE5XUmhaREUzTUdVd09UUTJaZz09IiwicmVnIl0=';
$queryArray =  parse_url($url);

the stream argument will be contained within

$queryArray['query'];

This will be an array if there is more than one argument

var_dump($queryArray);

To see all its options

See here php parse_url

Working Example

<?php
$url = 'www.example.com';
$url .='/get_file.php?stream=WyJPRUU1TkRWRk5VUXpSVFJGUXpFM1FUb3hNemcxTWpFME5Ua3lMamMzTlRRNlpHWTBZV00wTUdVNU16ZzJObVZqTkdFNU9HSXdaVEptT0dGaE5XUmhaREUzTUdVd09UUTJaZz09IiwicmVnIl0=';
$queryArray =  parse_url($url);
echo $queryArray['query']."<br>"."<br>"."<br>";
var_dump($queryArray);
?>

will return

stream=WyJPRUU1TkRWRk5VUXpSVFJGUXpFM1FUb3hNemcxTWpFME5Ua3lMamMzTlRRNlpHWTBZV00wTUdVNU16ZzJObVZqTkdFNU9HSXdaVEptT0dGaE5XUmhaREUzTUdVd09UUTJaZz09IiwicmVnIl0=


array(2) { ["path"]=> string(28) "www.example.com/get_file.php" ["query"]=> string(155) "stream=WyJPRUU1TkRWRk5VUXpSVFJGUXpFM1FUb3hNemcxTWpFME5Ua3lMamMzTlRRNlpHWTBZV00wTUdVNU16ZzJObVZqTkdFNU9HSXdaVEptT0dGaE5XUmhaREUzTUdVd09UUTJaZz09IiwicmVnIl0=" }

Answer 2

You could try preg_match:

$found = preg_match("/stream=(.+)'/", $html, $match);
if ( $found ) {
    echo $match[1]; 
}
