What potential issues can arise when using numeric strings with leading zeros in PHP?

When using numeric strings with leading zeros in PHP, the leading zeros indicate that the number is being treated as an octal (base 8) number. This can lead to unexpected behavior or errors when performing arithmetic operations or comparisons. To avoid this issue, you can explicitly convert the numeric string to an integer using the `intval()` function. 

$numericString = '0123';
$number = intval($numericString);
echo $number; // Output: 123
