  PHP at AllExperts
PHP was originally designed as a small set of Perl scripts, followed by a rewritten set of CGI binaries written in the C programming language by the Danish-Canadian programmer Rasmus Lerdorf in 1994 to display his résumé and to collect certain data, such as how much traffic his page was receiving.
PHP can be used with a large number of relational database management systems, runs on all of the most popular web servers and is available for many different operating systems.
PHP primarily acts as a filter which takes a file containing text and special PHP instructions and converts it to another form for display.

PHP's ease of use and similarity with the most common structured programming languages—most notably C and Perl (and from version 5, Java)—allows most experienced programmers to start developing complex applications with a minimal learning curve.
PHP was originally designed as a small set of Perl scripts, followed by a rewritten set of CGI binaries written in C by Rasmus Lerdorf in 1994 to display his résumé and collect some data, such as how many hits it was generating.
Destructors — PHP 5 introduces a destructor concept similar to that of other object-oriented languages, such as Java: When the last reference to an object is destroyed, the object's destructor (a class method named __destruct() that receives no parameters) is called before the object is freed from memory.

 The PHP 5 Data Object (PDO) Abstraction Layer and Oracle   (Site not responding. Last check: 2007-10-14)
PHP is largely a volunteer driven project; although there are a handful of regular "core" contributors, none of us are paid full time to sit down and develop PHP.
The PDO extension is modular, allowing you to load a driver for your database backend at runtime, without having to recompile or reinstall your entire PHP distribution.
PDO is deliberately somewhat type agnostic in that it prefers to represent data as strings instead of converting to integer or double types.

 An introduction to Service Data Objects for PHP
Data objects can automatically record their change history that can then be used by a DAS to detect collisions when applying changes back to an enterprise information system.
PDO (not to be confused with SDO) aims to provide a consistent API for the common capabilities found in most relational database APIs.
PDO provides a simple object view of results, but does not attempt to normalize those results (one row of the result set equals one object, regardless of whether there are multiple tables represented in the result).

Due to PHP's popularity, a new breed of programmer has emerged—one who is familiar only with PHP, which in turn forced open the door toward a command+line+interface for PHP, along with support for GUI library such as GTK and text mode libraries like Ncurses and Newt.

 Connect PHP to DB2 and Cloudscape via PDO
PHP 5.1 is set to ship with a brand-new database connectivity layer known as PHP Data Objects (PDO).
PDO is modular in structure, separated into a common core that provides the API that you use in your scripts (PDO itself), and one or more driver extensions that bridge PDO to the native RDBMS client API libraries.
PDO will simply set the error code for you to inspect using the errorCode() and errorInfo() methods on both the statement and database objects; if the error resulted from a call on a statement object, you would invoke the errorCode() or errorInfo() method on that object.

 M6.Net - PHP Information
PHP was originally designed to be used in conjunction with a web server, and acts as a filter which takes a file containing text and special PHP instructions and converts it to another form for display.
PHP does not enforce the declaration of variables prior to their use, and variables which have not been initialized can have operations (such as concatenation) performed on them; an operation on an uninitialized variable raises an E_NOTICE level error, but this is hidden by default.
PHP's "Safe Mode" can emulate the security behavior of the OS to partially overcome this problem, but this is considered an imperfect solution.

 PHP: PDO Functions - Manual
It is recommended that you build PDO as a shared extension, as this will allow you to take advantage of updates that are made available via PECL.
PDO offers you a choice of 3 different error handling strategies, to fit your style of application development.
PDO will simply set the error code for you to inspect using the PDO->errorCode() and PDO->errorInfo() methods on both the statement and database objects; if the error resulted from a call on a statement object, you would invoke the PDOStatement->errorCode() or PDOStatement->errorInfo() method on that object.

 PHP Help: PDO Functions
If you're using the PDO ODBC driver and your ODBC libraries support ODBC Connection Pooling (unixODBC and Windows are two that do; there may be more), then it's recommended that you don't use persistent PDO connections, and instead leave the connection caching to the ODBC Connection Pooling layer.
The ODBC Connection Pool is shared with other modules in the process; if PDO is told to cache the connection, then that connection would never be returned to the ODBC connection pool, resulting in additional connections being created to service those other modules.

PHP 5.1 is now in beta, and introduces PHP Data Objects (PDO).
PHP developers have been achieving this for years using database abstraction layers, at first homegrown, then open source, and finally official.
This is the first time such an abstraction layer will be completely built into PHP, and not a layer of PHP code sitting on top of it, however.

 U2 PDO Driver, Part 1: Write a PHP Data Objects driver for U2
PHP is a widely used open source general-purpose scripting language that is especially well-suited for Web development and can be embedded into HTML.
PDO provides a data-access abstraction layer, which means that you use the same functions to issue queries and fetch data regardless of which database you're using.
To use PDO to connect to a database, you need to instantiate the PDO class with parameters of data source name (DSN), user name, and password for the user name.

Many of us in desperate search for good ORM tools for PHP end up finding existing PHP persistence packages are either insufficient to address the problems we face, or unnecessarily complex that demand a steep learning curve that not many of us are able or willing to afford.
The goal of this project is to design a lightweight and easy-to-use persistence solution for PHP.
In fact, it helps you in many aspects if you have good SQL skills, especially when it comes to efficient object query, however most of the time with EZPDO you don’t need to simply because it takes care of interfacing with databases without you even knowing.
