How can conditional statements like "if" and "elseif" be effectively used in PHP scripts?

Conditional statements like "if" and "elseif" can be effectively used in PHP scripts to control the flow of the program based on certain conditions. By using these statements, you can create branches in your code that execute different blocks of code depending on whether a condition is true or false. This can help you create more dynamic and responsive scripts that react to different inputs or situations. 

// Example of using if and elseif statements in PHP
$number = 10;

if ($number > 0) {
    echo "Number is positive";
} elseif ($number < 0) {
    echo "Number is negative";
} else {
    echo "Number is zero";
}
