How can the use of echo statements and var_dump be beneficial in debugging PHP scripts that involve complex if-else conditions?

When debugging PHP scripts that involve complex if-else conditions, using echo statements and var_dump can be beneficial to track the flow of the program and inspect the values of variables at different stages. By strategically placing echo statements within the if-else blocks, you can see which condition is being met and which block of code is being executed. Similarly, using var_dump on variables can help you understand their values and types, aiding in identifying any logical errors in the conditions. 

<?php
// Example PHP script with complex if-else conditions
$number = 10;

if ($number > 5) {
    echo "Number is greater than 5";
} else {
    echo "Number is less than or equal to 5";
}

var_dump($number);
?>
