	1. DB eSession		error handling

Supplied by: Lawrence Osiris <e-mail contact>

MySQL based session management

This package is meant to manage session data stored in a MySQL database using PHP built-in session handling support.

General features:

- Stores session data in a MySQL table using session handler built-in PHP.
- Handle session expiration and cleanup.
- Supports the changes of session related configuration settings (including of PHP 5).
- Allows for normal or persistent MySQL database connections.
- Access to opened MySQL resource connection to use in your script.
- Can use a previously open database connection resource handle.
- Supports session identifiers with between 12 and 32 characters long.
- Custom or changeable database, table and column names.
- Has an option to create new session identifiers (you supply, class or PHP builds).
- Can initiate buffered output (using ob_start) within the class.
- A session_start() automatically initiated within the class.
- Can send 'Cache-Control:' header output within the class (fixes IE6 bug).
- Ability to retrieve a specific sessions expiration date and time.
- Retrieve current session life setting in seconds or minutes.
- Retrieve a numeric total of the number of active and inactive sessions in table.
- Facility to make assignment and retrieval of session variables easier.
- Has the ability to create manual URIs and links that include session name and ID.
- Has the ability to retrieve what the MySQL server version number is.
- An adequate form of encryption and decryption functions are included and used automatically when libmcrypt is not installed.

Security features:

- Standard user inactivity time-out handled automatically.
- Absolute user logoff time-out capability (session will be terminated no matter what after a number of designated minutes and seconds have elapsed).
- Ability to lock and unlock a particular session or all sessions. When a session is locked, it is immediately not available for use.
- User to session verification using IP address and browser information.
- Security level (code) clearance for each session or web page.
- Encrypt and decrypt as desired each session field.
- Encrypt and decrypt an extra session field to compare against original (to detect against possible tampering).
- Encrypt and decrypt the whole session data in the table (essentially obscuring session variable names in table). Can be used in combination with per session field encryption, resulting in double encryption security.
- A new encryption initialization vector is created every time values change.
- Ability to manually delete a particular session or all sessions.
- The users IP address and web browser is recorded as part of the session for tracing information.

Other features:

- Support for multiple language error and warning messages.
- Support of a default language as well as current active language settings.
- Basic or detailed (with SQL syntax) error and warning reporting.
- Buffered error and warning messages.
- Option for class to stop execution or not upon encountering an error and warning. Class can display errors and warnings automatically or control in your script.
- Can select font color and size separately for error and warning messages.
- The code has lots of comments and formatted within 82 characters wide.
- Full documentation (only provided in English) is included.
- Code use examples provided, including a basic authentication (login/logout) process.
- SQL text file provided for creating the MySQL session table.

	2. Error Handler		error handling

Output PHP execution errors information

This class is meant to assist in debugging of PHP scripts by handling execution errors outputing formatted error context information.

It includes utitilty functions to show the source code where the errors appear.

	3. Secure Media		error handling

Supplied by: Florian Metzger <e-mail contact>

Protect Flash files from hotlinking by other sites

The Apache mod_rewrite is often used to protect images and other types of media files from hotlinking from other sites, that make them appear in their pages although they are served from the original sites.

However, mod_rewrite can be used to protect the service of Flash files against hotlinking because these are embedded in pages using the <object> tag and in this case the browsers do not send a referer when requesting the Flash file from the origin server.

This class provides an alternative solution that works by generating a access key that is used to compose the URL used in the object tag but it is only valid only during a limited period of time.

The class takes as options the location of server directory where is the file to be protected, a password and the limit of time during which the access key is valid.

When the class validates the access key, it serves the real Flash file if the key is valid, or serves an error Flash file otherwise.

	4. Zebra_Session, a wrapper for PHP’s default session handling functions, using MySQL for storage		error handling

Supplied by: Stefan Gabos <e-mail contact>

Session handler that stores session data in MySQL

Zebra_Session is a PHP class that acts as a wrapper for PHP’s default session handling functions but instead of storing session data in flat files it stores them in a MySQL database, thus providing both better security and better performance.

The Zebra_Session class is also a solution for applications that are scaled across multiple web servers (using a load balancer or a round-robin DNS) and where the user’s session data needs to be available. Storing sessions in a database makes them available to all of the servers!

This class is was inspired by John Herren’s code from the Trick out your session handler article and Chris Shiflett’s code from his book Essential PHP Security, chapter 8, Shared Hosting, Pg. 78-80.

Zebra_Session‘s code is heavily commented and generates no warnings/errors/notices when PHP’s error reporting level is set to E_ALL.

	5. Error Handler Class		error handling

Supplied by: Frank Mullenger <e-mail contact>

Handle PHP scripts execution errors

This class can be used to handle PHP scripts execution errors.

It provides an error handler callback function that may execute several types of actions when an PHP runtime error is triggered.

Currently it can either log the errors to a file, send a message to a given e-mail address, or show the error details on the current page if the user is a developer accessing the site from machine with a given IP address.

	6. Error Class		error handling

Handle errors sending notification messages

This package can be used to handle application errors by sending notification e-mail messages.

The package is based on code originally written for MySQL Eventum project.

It composes and sends a message to a given recipient with information about an error that occurred.

The message includes details about the error such as the script name, the error line number, the current request script, the user IP address, the request referrer, the user browser, and a backtrace of the stack of functions that triggered the error.
