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!
