My question is very similar to this question but in my case I am wanting to know if the stream returned by stream_socket_client is open and writeable.
I know that stream_socket_client will return FALSE if the stream could not be opened, but I am needing to detect later on if the stream has been closed by the server (or closed due to some network error, for example).
At the moment I'm just doing...
$fp = stream_socket_client($apns_url, $error_code, $error_string, $timeout_secs, STREAM_CLIENT_CONNECT, $ctx); //looping through / sending data if (!fp) { //re-open connection }
...but I'm not sure if my if (!fp) {...} check is sufficient?
Use stream_get_meta_data for checking if stream is writable.
$meta = stream_get_meta_data($fp);
if(is_writable($meta['uri'])) {
// stream is writable
}
Use feof for checking if stream is open.
Returns TRUE if the file pointer is at EOF or an error occurs (including socket timeout);Try checking for end of file instead of checking if it is false
while (!feof($fp)) {...}
