In what ways can simple debugging techniques, such as echoing values, help identify PHP array comparison problems?

Simple debugging techniques, such as echoing values, can help identify PHP array comparison problems by allowing you to see the actual values of the arrays being compared. By echoing the arrays before and after the comparison, you can easily spot any differences or inconsistencies that may be causing the comparison to fail. 

$array1 = [1, 2, 3];
$array2 = [1, 2, 4];

echo "Array 1: ";
print_r($array1);
echo "Array 2: ";
print_r($array2);

if ($array1 == $array2) {
    echo "Arrays are equal";
} else {
    echo "Arrays are not equal";
}
