Subject: [PATCH] Make Zend Studio happy :)

Code Analyzer Output:

Variable $errno was used before it was defined (line 221)
Variable $errstr was used before it was defined (line 221)

Category: Coding Style

A local variable is used before it is defined.
Even though PHP initializes variables with empty values on the first use,
it is considered a good practice to explicitly initialize variables
to make code more readable and avoid unnecessary bugs.
