What potential issues can arise when using backticks (`) as separators in PHP number formatting?

Using backticks (`) as separators in PHP number formatting can cause syntax errors because backticks are used for shell execution in PHP. To avoid this issue, you can use single quotes (') or double quotes (") as separators instead. 

// Incorrect usage of backticks as separators
$number = 1000000;
$formatted_number = number_format($number, 2, "`", "`");
echo $formatted_number; // This will result in a syntax error

// Corrected code using single quotes as separators
$formatted_number = number_format($number, 2, "'", "'");
echo $formatted_number; // Output: 1'000'000.00
