How can I add leading zeros to a number in PHP when displaying it?

When displaying a number in PHP, you can add leading zeros to it by using the str_pad() function. This function allows you to pad a string with a specific character (in this case, zeros) to a certain length. You can specify the total length you want the number to be, and the function will add the necessary number of leading zeros to achieve that length. 

$num = 7;
$padded_num = str_pad($num, 3, '0', STR_PAD_LEFT);
echo $padded_num; // Output: 007
