PHP Using a variable when calling a static method

I’ve read through a few different posts on here (I.E. PHP Using a variable when calling a static method) when trying to use a variable on a static function, but I just can’t seem to get the call_user_func_array() function to work the same as if I was able to call the variable directly in the class name.

PHP >= 5.3.0 Method:

$data = $factory_model::by_array(array(
    $form_fields['name_field']  => $value
));

PHP < 5.3.0 Method:

$data = call_user_func_array(array($factory_model, 'by_array'), array(  
    $form_fields['name_field']  => $value
));

It’s some code that I’ve inherited so I can’t change that much on the models, but it should give the following output:

initiative_forecast_type Object
(
    [id:initiative_forecast_type:private] => 0
    [forecast_type:initiative_forecast_type:private] => TRTR
    [tstamp] => 2012-06-11 12:52:07
)

Which it does using the standard PHP 5.3 Method (My user input/value was ‘TRTR’)

But if I use the call_user_func_array method I get:

initiative_forecast_type Object
(
    [id:initiative_forecast_type:private] => 0
    [forecast_type:initiative_forecast_type:private] => 
    [tstamp] => 2012-06-11 12:52:07
)

So it’s not setting the ‘forecast_type’ field. I’ve uploaded the model here – http://pastebin.ca/2160201

For reference – $factory_model = initiative_forecast_type_factory

I thought the 2 call_user_func_array() function should work the same as the 5.3.0 method, but it doesn’t seem to be – Can anyone point me in the right direction?

Thanks!

Answer 1

call_user_func_array() expects the second parameter to be an array of the actual arguments for the function (the keys in the array would be disregarded). What you actually want is call_user_func().

call_user_func_array('func', array('foo' => 'bar')) === func('bar')
call_user_func_array('func', array(array('foo' => 'bar'))) === func(array('foo' => 'bar'))
call_user_func('func', array('foo' => 'bar')) === func(array('foo' => 'bar'))
