Exemplos

Exemplo #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();
?>

O exemplo acima produzirá:

Before: foo!
After: bar!
