How can debugging techniques like var_dump and echo help identify issues with conditional statements in PHP?

Debugging techniques like var_dump and echo can help identify issues with conditional statements in PHP by allowing you to inspect the values of variables within the condition. By using var_dump or echo to print out the values of variables being used in the conditional statement, you can see if they are what you expect them to be. This can help you pinpoint where the issue lies and make necessary adjustments to your conditional logic. 

// Example code snippet demonstrating the use of var_dump and echo for debugging conditional statements

$number = 10;

// Incorrect conditional statement
if ($number = 5) {
    echo "The number is 5";
} else {
    echo "The number is not 5";
}

// Debugging with var_dump and echo
var_dump($number); // Output: int(5)
echo "The actual value of number is: " . $number; // Output: The actual value of number is: 5

// Fixing the conditional statement
if ($number == 5) {
    echo "The number is 5";
} else {
    echo "The number is not 5";
}
