How can the use of var_dump() in PHP help in identifying and resolving issues with variables in conditional statements?

When working with conditional statements in PHP, it can sometimes be tricky to identify issues with variables that are being used in the conditions. By using the var_dump() function, you can easily inspect the values of these variables and determine if they are what you expect them to be. This can help in identifying any discrepancies and resolving issues with your conditional statements. 

$variable1 = 10;
$variable2 = 20;

var_dump($variable1, $variable2);

if ($variable1 > $variable2) {
    echo "Variable 1 is greater than Variable 2";
} else {
    echo "Variable 2 is greater than Variable 1";
}
