Bug description: fsockopen / fread fails unless exact length is given
Hi there... I wanted to fetch a webpage's contents. I used to be able to do
so by fread'ing with a huge number as length:
//////////////////
$fp=fsockopen( $host, $port, $errno, $errstr, 120 );
// assumed host and port were previously defined
$headers =
"GET /jornalmn/index.htm HTTP/1.0\r\n"
."User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)\r\n"
."Host: www.meionorte.com\r\n"
."Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
image/png, */*\r\n"
."Connection: Keep-Alive\r\n"
."Cache-Control: no-cache\r\n"
."\r\n";
fwrite($fp,$headers, strlen($headers));
$fetched_content = fread($fp,1000000000);
fclose($fp);
////////////////
Just recently this stopped working. Actually, I would eventually fetch the
page, but only after the connection timed out. After a lot of debugging I
found out I'd have sucess by specifying the EXACT file size to fread. I
had to adapt my scripts and tell them to either:
a) Capture the "Content-length" response value sent by the server (easy
way);
b) Fread little by little (128 bytes a time) and use
socket_get_status($fp) everytime to check for EOF condition and the number
of unread bytes.
