How can the var_dump function help in troubleshooting PHP array comparison issues?

When troubleshooting PHP array comparison issues, the var_dump function can help by displaying the contents of the arrays being compared. This can help identify any differences in the array structures or values that may be causing the comparison to fail. By using var_dump, you can easily see the elements of each array and pinpoint where the issue lies in the comparison process. 

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

var_dump($array1);
var_dump($array2);

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