What potential issues can arise when using the number_format function in PHP?

One potential issue that can arise when using the number_format function in PHP is that it may not handle decimal points properly when formatting large numbers. To solve this issue, you can use the bcdiv function to perform the division operation with precision. 

$number = 123456789.123456789;
$precision = 8;

$formatted_number = number_format(bcdiv($number, 1, $precision), $precision);

echo $formatted_number;
