パラメータ
classname- The class in which to redefine the method
methodname- The name of the method to redefine
args- Comma-delimited list of arguments for the redefined method
code- The new code to be evaluated when
methodnameis called closure- A closure that defines the method.
flags- The redefined method can be
RUNKIT7_ACC_PUBLIC,RUNKIT7_ACC_PROTECTEDorRUNKIT7_ACC_PRIVATEoptionally combined via bitwise OR withRUNKIT7_ACC_STATIC doc_comment- The doc comment of the method.
return_type- The return type of the method.
is_strict- Whether the method behaves as if it was declared in a file with
strict_types=1.

例
例1 runkit7_method_redefine() example
<?phpclass 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' methodrunkit7_method_redefine( 'Example', 'foo', , 'return "bar!\n";', RUNKIT7_ACC_PUBLIC);// output Example::foo() (after redefine)echo "After: " . $e->foo();?>
上の例の出力は以下となります。
Before: foo! After: bar!
