    例

    例1 runkit7_method_redefine() example

    <?php
    class Example {
    function     foo() {
    return     "foo!\n";
    }
    }

    // create an Example object
    $e = new Example();

    // output Example::foo() (before redefine)
    echo "Before: " . $e->foo();

    // Redefine the 'foo' method
    runkit7_method_redefine(
    'Example',
    'foo',
    '',
    'return "bar!\n";',
    RUNKIT7_ACC_PUBLIC
    );

    // output Example::foo() (after redefine)
    echo "After: " . $e->foo();
    ?>

    上の例の出力は以下となります。

    Before: foo!
After: bar!
