Hello,

I cannot reproduce the error in PHP 7.0. Based on the error log, the problem seems to happen when the id of the SVG element is set, but as I said, it works ok for me. Are the other examples working for you?

[anJka]

no in fact all examples throw error
maybe I installed it wrong with composer?

Same here. I'm looking at the code trying to fix it..

[momolafrooo]

me too i got the same problem who can help me ?

Ok the original problem is a NOTICE in statement in b1t\svgf\SVGFElement.pgo line 69

$variable = $item ?: NULL;

$item is undefined and $cariable is never use just comment it out.

[PulfordN]

The later problem is a call of call_user_func in b1t\svg\SVGObject.php one in the setter and one in the getter.

wanting a quick fix I did the following
setter
call_user_func($call_to_user_func,$attribute_value);
replaced with
$this->$string_set_method_name = $attribute_value;

getter
return call_user_func($call_to_user_func,$attribute_value);
replaced with
return $this->$string_get_method_name();

It works for trhe examples
