|
This function returns structured information about the variable that is
|
|
passed to this function. It is similar to <function>var_dump</function>
|
|
with two exceptions. The first one is that the returned representation is
|
|
valid PHP code, the second that it will also return protected and private
|
|
properties of an object with PHP 5.
|
|
</simpara>
|
|
<simpara>
|
|
You can also return the variable representation by using &true; as
|
|
second parameter to this function.
