Are there any best practices for maintaining leading zeros in PHP when working with numbers?

When working with numbers in PHP, leading zeros may be lost when converting numbers to strings or performing calculations. To maintain leading zeros, you can use the `str_pad()` function to add zeros to the left of the number if needed. 

$number = 123;
$length = 5;
$numberWithZeros = str_pad($number, $length, '0', STR_PAD_LEFT);

echo $numberWithZeros; // Output: 00123
