What is the significance of the distinction between MB and MiB in PHP file size calculations?

The distinction between MB (megabyte) and MiB (mebibyte) is important in PHP file size calculations because they represent different units of measurement. MB is based on the decimal system (1 MB = 1,000,000 bytes), while MiB is based on the binary system (1 MiB = 1,048,576 bytes). When working with file sizes in PHP, it's crucial to use the correct unit to ensure accurate calculations. 

function convertBytesToMiB($bytes) {
    return $bytes / 1048576;
}

$fileSizeInBytes = 1048576; // 1 MiB in bytes
$fileSizeInMiB = convertBytesToMiB($fileSizeInBytes);
echo $fileSizeInMiB . ' MiB'; // Output: 1 MiB
