+/**
+ * ZendCodeAnalyzerTask analyze PHP source code using the ZendCodeAnalyzer included in Zend Studio 5.1
+ *
+ * Available warnings:
+ *
+ * zend-error var: Deprecated. Please use the public/private/protected modifiers
+ * var-arg-unused Function argument 'parser' is never used.
+ * var-once Variable 'comment' encountered only once. May be a typo?
+ * var-value-unused Value assigned to variable 'args' is never used
+ * return-empty-val Function 'set_object' has both empty return and return with value.
+ * if-if-else In if-if-else construction else relates to the closest if. Use braces to make the code clearer.
+ * bool-assign Assignment seen where boolean expression is expected. Did you mean '==' instead of '='?
+ * var-use-before-def Variable 'matches' is used before it was assigned.
+ * empty-cond Condition without a body
+ * var-ref-notmodified Function parameter 'parser' is passed by reference but never modified. Consider passing by value.
+ * include-var include/require with user-accessible variable can be dangerous. Consider using constant instead.
+ * expr-unused Expression result is never used
+ * bad-escape Bad escape sequence: \/, did you mean \\/?
+ * var-use-before-def-global Global variable 'argv' is used without being assigned. You are probably relying on register_globals feature of PHP. Note that this feature is off by default.
+ * call-time-ref Call-time reference is deprecated. Define function as accepting parameter by reference instead.
+ * return-noref Function 'loadlintschema' returns reference but the value is not assigned by reference. Maybe you meant '=&' instead of '='?
+ * unreach-code Unreachable code in function 'loginUser'.
+ * var-global-unused Global variable 'fixErrors' is defined but never used.
+ * break-depth Break/continue with depth more than current nesting level.
+ *
