    When we will use unlink() then this function will delete to file test.jpg from given path.

    PHP

    <?php
unlink("image/test.jpg");
?>

    When we will use unset() then this function will remove content initialized with the PHP variable $test_text. After using unset() $test_text variable will be empty.

    PHP

    <?php
    $test_text = "Welcome to EVON";
    unset($test_text);
    if(isset($test_text)) {
        echo "<strong>My welcome text is: </strong><i>" . $test_text . "</i>";
    } else {
        echo "<strong>My welcome text is: </strong> empty";
    }
    //output will be My welcome text is: empty
?>
    php unlink() function unset()
