Hi,

If you open an UDP connection to a non open udp port
with fsockopen, fread reads the requested length, but
the content is sometimes wrong (nonsensical data)

This short script demonstrate the problem:

<?php
header ('Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0, no-risk, no-fun');
header ('Pragma: no-cache');

// Please replace the ip address with an existing host
$fp = fsockopen("udp://192.168.0.1", 33334, $errno, $errstr);
if (!$fp) {
    echo "ERROR: $errno - $errstr<br>\n";
}
else {
    fwrite($fp,"\n");
    $content=fread($fp, 40);
    echo "<hr>read length: ".strlen($content)."<hr>";
    echo $content."<hr>";
    echo bin2hex($content)."<hr>";
    fclose($fp);
}
echo "Finished @ ".time();
?>

I've test it with the lastest cvs version (28.10.2002)

Regards,

Steve
