範例

範例 1. classkit_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
classkit_method_redefine(
    
'Example',
    
'foo',
    
'',
    
'return "bar!\n";',
    
CLASSKIT_ACC_PUBLIC
);

// output Example::foo() (after redefine)
echo "After: " . $e->foo();
?>

The above example will output:

Before: foo!
After: bar!
