Hi,
I have spent several hours with a strange problem with reflection.
There's an object of an external lib with a private field and I have to overwrite its values. Because there is no public method I am using ReflectionProperty like this:
$reflProp = new \ReflectionProperty(Extension::class, 'classes');
$reflProp->setAccessible(true);
$reflProp->setValue($extension,['new', 'values']);
var_export($extension->getClasses());
The field is of type array and contains several entries. The problem is, that the private field has not been overwritten by $reflProp->setValue(). Instead it looked like, the array of the private field has been merged with my new array.
I tried different things but nothing worked. I have tried to create a small script which could show the problem, but it wasn't reproducible.
The last thing I tried was, to call
var_export($reflProp->getValue($extension));
instead of
var_export($extension->getClasses());
That returns exactly the correct value. So my question is if somebody could imagine why $reflProp->getValue() returns the value I am trying to set, but accessing the field with an object member method (getClasses) returns a merged array.
I am using PHP 5.6.26 (x86, TS) on Windows 10.
Best regards,
Christian
