Re: fread() question

Wouldn't it be easier to use something like the following? 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? Read more about it at http://se2.php.net/manual/en/function.fgets.php //Simon Seairth Jacobs wrote:

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. --- Seairth Jacobs seairth@seairth.com
