How can error logging and debugging be effectively utilized to troubleshoot issues in PHP scripts dealing with binary data?

When dealing with binary data in PHP scripts, it's important to properly handle errors and debug any issues that may arise. One way to effectively troubleshoot problems is to enable error logging and use debugging tools like var_dump() or print_r() to inspect variables and data structures.

// Enable error logging
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Debugging with var_dump()
$binaryData = "\x48\x65\x6c\x6c\x6f";
var_dump($binaryData);

// Debugging with print_r()
$binaryArray = unpack("C*", $binaryData);
print_r($binaryArray);
