How can one ensure the reliability and accuracy of sorting algorithms in PHP when dealing with special characters or unique data formats?

Special characters or unique data formats can sometimes cause issues with sorting algorithms in PHP. To ensure reliability and accuracy, one can use the `setlocale` function to set the locale to a specific language or region, which can help with sorting special characters correctly. Additionally, using the `uasort` function with a custom comparison function can handle unique data formats effectively. 

// Set the locale to a specific language or region
setlocale(LC_COLLATE, 'en_US.UTF-8');

// Custom comparison function for uasort
function customSort($a, $b) {
    return strcoll($a, $b);
}

// Data to be sorted
$data = ['apple', 'banana', 'cherry', 'éclair', 'ümlaut'];

// Sort the data using uasort with custom comparison function
uasort($data, 'customSort');

// Output sorted data
print_r($data);
