Description:
------------
Manual says PDOStatement::execute() signature is:

bool PDOStatement::execute  ([  array $input_parameters = array()  ] )

But in fact it is:

bool PDOStatement::execute  ([  $input_parameters = null  ] )

Test script:
---------------
<?php

class DBStatement extends PDOStatement
{
    public function execute(array $input_parameters = array())
    {
        return parent::execute($input_parameters);
    }
}

$PDO = new PDO('mysql:host=127.0.0.1', 'root', '');
$PDO->setAttribute(PDO::ATTR_STATEMENT_CLASS, array('DBStatement'));

Expected result:
----------------
No errors

Actual result:
--------------
Strict Standards: Declaration of DBStatement::execute() should be compatible with that of PDOStatement::execute() in /media/ext/Web/htdocs/test/bug.php on line 9

Pierrick, why don't you commit that patch the src? And add a changelog entry if reasonable for PDOStatement::execute() :)
 [2012-01-30 05:52 UTC] larry at ldrutledge dot com 
The situation appears to be unchanged in 5.3.9. The manual still shows a type hint of array but a method in an extended class still triggers a warning unless the type hint is omitted.

This seems been forgotten by pierrick.
 [2012-09-10 02:32 UTC] laruence@php.net 
maybe change to doc problem, there maybe already some user defined their extended 
class with the *wrong* signature.

I never committed this patch because it was breaking some php code by adding 
strict errors. We should (as said in the previous comment) update the 
documentation.

I'm assigning this to you Ilia since you're the PDO primary maintainer. Do you 
also think it's best to just update the documentation ? Thanks for your feedback

I think the patch make sense, we should update the docs to reflect the patch.
 [2012-11-17 06:08 UTC] pierrick@php.net 
Ok then I'll commit it on 5.3 and > or on 5.5 and > ?

This is still not fixed in the documentation, it would be great if the 
documentation could be updated to reflect the real situation!

Using PHP 5.4.6 I noticed that the Strict Standards error message was improved, now it includes the expected signature, which actually helps more than before:

Strict Standards: Declaration of DBStatement::execute() should be compatible with PDOStatement::execute($bound_input_params = NULL) in Unknown on line 0

If it won't get patched, please, don't forget to update the docs! (if php-doc was already mirrored on GitHub I'd have done it myself – hint)

IMO, this is not a documentation problem, but rather an
implementation bug. While the ARG_INFO is untyped[1], the
respective ZPP expects a nullable array[2]. Actually, this
inconsistency should be fixed, instead of weakening the docs.

The arginfo is now fixed in master[1] (fixing it for PHP 7 would
constitute a BC break), so I'm changing to doc bug.
