What are the potential implications of performing arithmetic operations on ZEROFILL integers in PHP?

Performing arithmetic operations on ZEROFILL integers in PHP may lead to unexpected results due to the way ZEROFILL integers are stored as strings with leading zeros. To avoid this issue, it is recommended to first convert the ZEROFILL integers to regular integers before performing any arithmetic operations. 

// Convert ZEROFILL integer to regular integer before performing arithmetic operations
$zerofillInt1 = '000123';
$zerofillInt2 = '000045';

$int1 = (int)$zerofillInt1;
$int2 = (int)$zerofillInt2;

$result = $int1 + $int2;

echo $result; // Output: 168
