How can an array in PHP be converted into a string for comparison purposes?

When comparing arrays in PHP, you may need to convert them into strings for easy comparison. One way to do this is by using the `serialize()` function to serialize the array into a string. This serialized string can then be compared with another serialized array string using standard string comparison operators. 

$array1 = [1, 2, 3];
$array2 = [1, 2, 3];

$string1 = serialize($array1);
$string2 = serialize($array2);

if ($string1 === $string2) {
    echo "Arrays are equal";
} else {
    echo "Arrays are not equal";
}
