Is it possible to format numbers to have leading zeros in PHP?

Yes, it is possible to format numbers to have leading zeros in PHP using the `str_pad()` function. This function can be used to pad a string with a specific character (in this case, a zero) to a certain length. By converting the number to a string and then using `str_pad()`, we can easily add leading zeros to the number. 

$num = 7;
$padded_num = str_pad($num, 2, '0', STR_PAD_LEFT);
echo $padded_num; // Output: 07
