    code

    The new code to be evaluated when method_name is called

    closure

    A closure that defines the method.

    flags

    doc_comment

    The doc comment of the method.

    return_type

    The return type of the method.

    is_strict

    Examples

    Example #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();
    ?>

    The above example will output:

    Before: foo! After: bar!
