Beispiel #1 runkit_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
runkit_method_redefine(
'Example',
'foo',
'',
'return "bar!\n";',
RUNKIT_ACC_PUBLIC
);
// output Example::foo() (after redefine)
echo "After: " . $e->foo();
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Before: foo! After: bar!
