Betreff: [PHP-DEV] Problem with overwriting private property value with ReflectionProperty
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
Oh, sorry. I have found the problem now, after trying to overwrite the value with a string instead of an array. The object I had the problem with, has been extended by another class the the getClasses merged the field with another array.
Sorry for the noise.
