          mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true));
}


function findinside($tag, $content)
{
    $pattern = '/<div class='.preg_quote($tag).' >(.*?)<div>/si';
    preg_match_all($pattern, $content, $m);
    return $m[1];
}


$tag = 'tresc';
$data="<div class=\"tresc\">text1<strong>text2</strong><br><strong>text3</strong></div>";
$out = findinside($tag, $data);
 print_r ($out);

PHP:

 

Before I look through the code, have you made sure you can use file_get_contents with URLs? Sometimes hosts disallow this function as a security feature. Check that allow_url_fopen is enabled in a phpinfo file.

 

I enabled it and now it returns : Array ( ) , so what now ?

 

<?php

function file_get_contents_utf8( $fn )
{ /* We'll run with your function */
    $content = file_get_contents( $fn );
    return mb_convert_encoding( $content, 'UTF-8', mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true) );
}

$file = file_get_contents_utf8('http://uwaga.onet.pl/index.html');
preg_match('/<div class=tresc>(.*?)<\/div>/', str_replace(array("\n", "\r"), ' ', $file), $matches);
list(, $value) = $matches;

echo $value;

?>

PHP:

Returns:
