What are the best practices for converting hexadecimal data back to decimal format in PHP and saving it to a file?

When converting hexadecimal data back to decimal format in PHP and saving it to a file, it is important to use the hexdec() function to convert the hexadecimal string to a decimal number. After converting the data, you can save it to a file using file_put_contents() function. Make sure to specify the correct file path and mode (e.g., 'w' for write mode) when saving the decimal data to a file. 

// Convert hexadecimal data to decimal format
$hexData = '1A2B3C';
$decimalData = hexdec($hexData);

// Save decimal data to a file
$filePath = 'decimal_data.txt';
file_put_contents($filePath, $decimalData, FILE_APPEND);
