What could be the potential cause of the "parse error" when using the if statement to compare IP addresses in PHP?

The "parse error" when using the if statement to compare IP addresses in PHP could be caused by incorrect syntax or formatting in the comparison. To solve this issue, ensure that the IP addresses are properly formatted and compared using the correct syntax for string comparison in PHP.

php 
// Example code snippet with corrected syntax for comparing IP addresses
$ip1 = "192.168.1.1";
$ip2 = "192.168.1.2";

if ($ip1 === $ip2) {
    echo "IP addresses are the same";
} else {
    echo "IP addresses are different";
}
