What steps can be taken to troubleshoot and resolve discrepancies in data transmission length between PHP socket_write() and the receiving end?

When there are discrepancies in data transmission length between PHP socket_write() and the receiving end, it is important to ensure that both ends are using the same encoding and handling of data. Additionally, checking for any buffer overflows or data truncation issues can help resolve the problem. It may also be helpful to implement error handling and logging to track the data transmission process. 

// Set the encoding for both sending and receiving ends
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec" => 1, "usec" => 0)); // Set timeout for receiving data
socket_set_option($socket, SOL_SOCKET, SO_SNDTIMEO, array("sec" => 1, "usec" => 0)); // Set timeout for sending data

// Check for buffer overflows or data truncation issues
$bytes_sent = socket_write($socket, $data, strlen($data));
if($bytes_sent === false){
    // Handle error in data transmission
    echo "Error in data transmission: " . socket_strerror(socket_last_error());
}

// Implement error handling and logging
if($bytes_sent !== strlen($data)){
    // Log the discrepancy in data transmission length
    error_log("Data transmission length mismatch: Sent $bytes_sent bytes, expected " . strlen($data) . " bytes");
}
