Przykład #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
