Description:
------------
In code samples for the PDO object, objects are created with 
the assignment operator (=) instead of the reference operator 
(=&).

Reproduce code:
---------------
//Syntax used in code samples
$conn = new PDO( $dsn );

//How it actually works
$conn =& new PDO( $dsn );

Expected result:
----------------
The output shown below the corresponding code samples.

Actual result:
--------------
On windows, the first version doesn't report any errors, 
however any subsequent calls to methods of $conn results in 
the following warning: "SQL State [000000] No Error. PDO 
Constructor was not called."

If you use the =& operator (and make $conn a reference to the 
newly created object) everything works as expected.

this is not a documentation problem surely. PHP 5 deprecates the use of '=& new' syntax, as objects are always references.
Please try with latest PHP 5 version available and if the problem persists, reopen this bug, but not as a documentation problem.

In fact, I just found out that according to the online 
documentation, the syntax used in the docs is in fact correct.

However, the correct syntax does not work on PHP 5.1.1 on 
Win2K; so it is more a PDO related issue than documentation 
related.

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:

In addition to trying the latest release snapshot, please provide more information:

What PDO driver are you using?

What database (including version) are you connecting to?

What is the value of $dsn that you are passing to the PDO constructor?

Changed summary to more accurately reflect bug report.

I was trying to connect to SQLite version 3.
I tried different strings for $dsn, including:

"sqlite:test.db"
"sqlite::memory:"

I used only the drivers that came with PHP 5.1.1.

I just checked the ini directives, and found out that 
zend.ze1_compatibility_mode was turned on. Turning it off 
caused the object to behave as expected.

I am sorry for any inconvenience I have caused.

Maybe the PDO object should throw a warning when it's cloned.
