How can PHP developers effectively debug issues with if-else statements that involve complex conditions?

When debugging if-else statements with complex conditions in PHP, developers can use var_dump() or echo statements to print out the values of the variables involved in the conditions. This allows them to see the actual values being compared and identify any discrepancies. Additionally, breaking down the conditions into smaller parts and testing each part individually can help pinpoint where the issue lies. 

// Example of debugging if-else statements with complex conditions
$var1 = 10;
$var2 = 20;

if ($var1 > 5 && $var2 < 15) {
    echo "Condition is true";
} else {
    echo "Condition is false";
}

// Debugging by printing out the values of variables
var_dump($var1, $var2);
