Maybe try to specify the number of $maxlen bytes to read?

http://us4.php.net/file_get_contents

string file_get_contents  (  string $filename  [,  bool $use_include_path =
false  [,  resource $context  [,  int $offset = -1  [,  int $maxlen = -1
]]]] )

You could also do it the faster and "old fashioned" way:

$fh = fopen('/tmp/test.zip', 'r');
$data = fread($fh, filesize('/tmp/test.zip'));
fclose($fh); 

Or if it's multibyte maybe try this:

function file_get_contents_utf8($fn) {
     $content = file_get_contents($fn);
      return mb_convert_encoding($content, 'UTF-8',
          mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true));
}
