Data extraction from /Filter /FlateDecode PDF stream in PHP

header('Content-Type: text');           // I going to download the result of decoding
$n = "binary_file.bin";                 // decoded part in file in a directory
$f = @fopen($n, "rb");                  // now file is mine
$c = fread($f, filesize($n));           // now I know all about it 
$u = @gzuncompress($c);                 // function, exactly fits for this /FlateDecode filter
$out = fopen("php://output", "wb");     // ready to output anywhere
fwrite($out, $u);                       // output to downloadable file

Jingle bells! Jingle bells!…
