while (!feof ($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}This will read until there's nothing more to read. Isn't that what you're trying to do?

I have an open socket that I am reading from. The code looks like the following:
$contentLength = 0 + $this->response['headers']['content-length'];
do{ $status = socket_get_status($this->socket);
if( $status['eof'] == 1 ) { if( $this->clientOptions['debug'] & DBGSOCK ) echo("DBG.SOCK status eof met, finished socket_read\n"); break; }
if($status['unread_bytes'] > 0) {
if($contentLength > $status['unread_bytes']) { echo("DBG.SOCK reading {$status['unread_bytes']} bytes...\n"); $buffer = @fread($this->socket, $status['unread_bytes']);
$contentLength = $contentLength - $status['unread_bytes']; } else { $buffer = @fread($this->socket, $contentLength); $contentLength = 0; } } else { if( $this->clientOptions['debug'] & DBGSOCK ) echo("DBG.SOCK reading {$status['unread_bytes']} bytes...\n"); usleep(1); continue; }
$data .= $buffer; } while($contentLength > 0);
Now, the above code hangs (infinite loop, actually), ultimately returning something like:
DBG.SOCK reading 3993 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... DBG.SOCK reading 0 bytes... etc...
On the other hand, if I change the following lines:
$buffer = @fread($this->socket, $status['unread_bytes'] - 1);
$contentLength = $contentLength - $status['unread_bytes'] - 1;
Then I get something that looks like:
DBG.SOCK reading 3993 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... DBG.SOCK reading 1 bytes... etc...
until the entire response has been read (88771 bytes in this case). Also, this would mean that the effective fread would be:
$buffer = @fread($this->socket, 0);
However, if I just do:
$data = @fread($this->socket, $contentLength);
it works as expected. So what's going on?
For now, I will use the single command in place of the loop, but I really wanted to monitor the current unread bytes. Any thoughts appreciated.
