Bug description:$this keyword is treated like a variable under certain
circumstances
Description:
------------
When capitalising the first letter of the $this keyword to $This and then
assigning it to a variable (with appropiate class structures) like this:
"$Variable = $This->Class1->Function1();" causes PHP to throw an error and
not
display the page, when $This is changed to $this, it works fine.
Test script:
---------------
This test script is fit into two parts, for two separate files.
** UNCOMMENT THE LINES TO REPRODUCE PROBLEM
** FILE 1 ** (The file to be run)
Class Class1
{
Public $Class2Inst;
Public function __construct()
{
include("phpbug2.php"); // ******* Change this to the path of
the other
file.
$this->Class2Inst = new Class2;
//$Variable1 = $This->Class2Inst->Func1(); // This produces
error
//$Variable2 = $this->Class2Inst->Func1(); // This does not
produce
error
echo $Variable2;
}
}
$Class1Inst = new Class1;
** FILE 2 ** The file that gets included
Class Class2
{
Public function Func1()
{
return "Function 1 is being run";
}
}
Expected result:
----------------
The expected result is that Func1 within the Class2 class is run.
Actual result:
--------------
The $This keyword is treated like a variable, instead of like a keyword.
