How can debugging techniques be applied to identify discrepancies between expected and actual results in PHP variable assignments?

To identify discrepancies between expected and actual results in PHP variable assignments, you can use debugging techniques such as printing out the values of variables at different points in your code, using var_dump() or echo statements. This will help you track the values of variables and identify where the issue may be occurring. Additionally, you can use conditional statements to check the values of variables and see if they match your expectations. 

// Example code snippet demonstrating debugging techniques for variable assignments
$expectedValue = 10;
$actualValue = 5;

// Debugging technique: print out the values of variables
echo "Expected value: " . $expectedValue . "<br>";
echo "Actual value: " . $actualValue . "<br>";

// Debugging technique: using var_dump() to display variable types and values
var_dump($expectedValue);
var_dump($actualValue);

// Debugging technique: using conditional statements to check values
if($expectedValue !== $actualValue){
    echo "Discrepancy found between expected and actual values!";
}
