code
       The new code to be evaluated when method_name

closureA closure that defines the method.
flags

       RUNKIT7_ACC_PROTECTED or
       RUNKIT7_ACC_PRIVATE optionally combined via bitwise OR with
       RUNKIT7_ACC_STATIC
      
doc_commentThe doc comment of the method.
return_typeThe return type of the method.

Exemple #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();
?>
L'exemple ci-dessus va afficher :
Before: foo! After: bar!
