[PHP] Weird problem with dynamic method invocation
- by Rolf
Hi everyone,
this time, I'm facing a really weird problem. I've the following code:
$xml = simplexml_load_file($this->interception_file);
foreach($xml->children() as $class) {
$path = str_replace('__CLASS_DIR__',CLASS_DIR,$class['path']);
if(!is_file($path)) {
throw new Exception('Bad configuration: file '.$path.' not found');
}
$className = pathinfo($path,PATHINFO_FILENAME);
foreach($class as $method) {
$method_name = $method['name'];
$obj = new $className();
var_dump(in_array($method_name,get_class_methods($className)));exit;
echo $obj->$method_name();### not a method ???
}
}
As you can see, I get the class name and method name from an XML file.
I can create an instance of the class without any problem. The var_dump at the end returns true, that means $method_name (which has 2 optional parameters) is a method of $className.
BUT, and I am pretty sure the syntax is correct, when I try: $obj-$method_name() I get:
Fatal error: Method name must be a string
If you have any ideas, pleaaaaase tell me :)
Thanks in advance,
Rolf
