If <parameter>obj</parameter> is an object, returns the name of the
|
|
parent class of the class of which <parameter>obj</parameter> is an
|
|
instance.
|
|
</para>
|
|
<para>
|
|
If <parameter>obj</parameter> is a string, returns the name of the parent
|
|
class of the class with that name. This functionality was added in PHP
|
|
4.0.5.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
Since PHP 5, <parameter>obj</parameter> is optional if called from the
|
|
object's method.
|
|
If called without parameter outside object, this function returns
|
|
&false; (or &null; with a warning before PHP 5.1.0).
