Bug description: read from UDP results wrong data
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
