What role does the use of a Hex editor play in troubleshooting issues with file downloads in PHP, and how can it help identify and resolve errors in file content?

When troubleshooting file download issues in PHP, using a Hex editor can help identify and resolve errors in file content by allowing you to inspect the raw hexadecimal data of the file. This can help pinpoint any discrepancies or unexpected characters that may be causing the issue with the file download.

$file_path = 'path/to/file.ext';

// Read the file content using a Hex editor
$file_content = file_get_contents($file_path);

// Output the hexadecimal representation of the file content
echo bin2hex($file_content);
