For some unknown reason, the normal laws of civilized society don’t seem to apply over interna- tional waters, or as soon as you’ve passed the first (of many) secu- rity checkpoints. On a flight, you’re forced to be in closer contact than you would ever allow under any circumstances with people you have never met in your life—and, most likely, would never want to have any- thing to do with if you knew them in the first place. Some of your fellow passengers are just plain inconsiderate—like the guy sitting next to you who takes off his shoes and the other one who drinks enough Martinis to kill a small horse. Airport security—not to be outdone by the very same people it is meant to server—is reaching new heights of stupidity. At one end of the line, an officer asks you to take off your shoes. “It’s optional, but if you don’t take them off they’ll search you at the other end of the line.” Well, duh… let’s see, should I take off my shoes now or everything else in the presence of that seven-feet-tall guard named “Bob” in thirty seconds? Um, let me think about it. On my way back from a recent trip to California, I sat right behind the security checkpoint and listened in on a screener who was performing a search on a fellow passenger-in-waiting who had actually refused to take off his shoes. The best part was the intro- duction, which went something like “Sir, could you step to the side please. Now, I will have to perform a search of your person because you ‘fit the profile.’ Of course, we can’t tell you what the profile is, but this will only take a moment.” So, on one side of the line someone tells you exactly “what the profile is,” and, on the other, someone else tells you that the pro- file is a secret. I hate to be stating the obvious, but that strikes me as slightly odd—then again, there is no limit to government silli- ness. Meanwhile, back in Canada our government is training more search dogs and pigs (yes, I said pigs) to sniff out smugglers. “Drugs,” you may be thinking? No. Illegally-imported food. It’s not the guy with the three-pound package of cocaine in his back- pack that we should be worried about—the real criminal is the eighty-year-old Italian lady with the salami in her purse. Until next month, happy readings!

DB_DataObject_FormBuilder 0.11.4 DDBB__DDaattaaOObbjjeecctt__FFoorrmmBBuuiillddeerr will aid you in rapid application development using the DDBB__DDaattaaOObbjjeecctt and HHTTMMLL__QQuuiicckkFFoorrmm packages. In order to have a quick but working prototype of your application, simply model the database, run DataObject's createTable script over it and write a script that passes one of the resulting objects to the FFoorrmmBBuuiillddeerr class. The FFoorrmmBBuuiillddeerr will automatically generate a sim- ple but working HHTTMMLL__QQuuiicckkFFoorrmm object that you can use to test your application. It also provides a processing method that will auto- matically detect if an iinnsseerrtt(()) or uuppddaattee(()) command has to be executed after the form has been submitted. If you have set up DataObject's links.ini file correctly, it will also automatically detect if a table field is a foreign key and will populate a selectbox with the linked table's entries. There are many optional parameters that you can place in your DataObjects.ini or in the properties of your derived classes, that you can use to fine-tune the form-generation, gradually turning the prototypes into fully-fea- tured forms, and you can take control at any stage of the process. DB 1.7.1 DB is a database abstraction layer providing: • An OO-style query API • Portability features that make programs written for one DBMS work with other DBMS's • A DSN (data source name) format for specifying database servers • Prepare/execute (bind) emulation for databases that don't support it natively • A result object for each query response • Portable error codes • Sequence emulation • Sequential and non-sequential row fetching as well as bulk fetching • Formats fetched rows as associative arrays, ordered arrays or objects • Row limit support • Transactions support • Table information interface • DocBook and phpDocumentor API documentation Cache_Lite 1.4.1 This package is a little cache system optimized for file containers. It is fast and safe (because it uses file locking and/or anti-corruption tests). XML_RPC 1.2.1 A PEAR-ified version of Useful Inc's XML-RPC for PHP. It has support for HTTP/HTTPS transport, proxies and authentication. I18Nv2 0.11.3 This package provides basic support to localize your application, like locale based formatting of dates, numbers and currencies. Beside that it attempts to provide an OS independent way to sseettllooccaallee(()) and aims to provide language, country and currency names translated into many languages. Maguma OpenStudio Maguma GmbH (Bolzano, Italy) will make the source code of Maguma Studio, Maguma's Windows- exclusive IDE, open! Beginning in March 2005 the full source code of Studio will be available for download and community participation. Maguma OpenStudio, as Maguma has named the product, is a milestone in the pursuit to the realization of Maguma's Open Source strategy. Maguma OpenStudio is a fast, easy and effective PHP IDE for beginners and professional developers alike. The newest product, the modular cross-plat- form IDE, Maguma Workbench, is Maguma’s second generation IDE and is also community focused through its flexibility to allows users to create custom modules for it. Maguma’s goal is to allow pro- grammers to "Have Fun Programming!" In March Maguma OpenStudio will be available for download on the Community site wwwwww pphhppwwiizzaarrdd nneett and on the Maguma Community site community hhttttpp::////ccoomm mmuunniittyy mmaagguummaa oorrgg// .

Check out some of the lastest offerings from PECL. big_int 1.0.0 Functions from this package are useful for number theory applications, or example in two-key cryptography. See tteessttss//RRSSAA pphhpp in the package for example of implementation of RSA-like cryptoalgorithm. The package has many bitset functions, which make it possible to work with arbitrary-length bitsets. This package is much faster than the one bundled into PHP BCMath and covers almost entirely the functions implemented in the PHP GMP extension without requiring any external libraries. Net_Gopher 1.0.0 An ffooppeenn(()) wrapper for retrieving documents via the gopher protocol. It includes additional function for parsing gopher directory entries. bz2_filter 1.1.0 A bzip2 compress/decompress stream filter implementation. It performs inline compression/decompression using the bzip2 algorithm on any PHP I/O stream. The data produced by this filter, while compatible with the payload portion of a bz2 file, does not include headers or trailers for full bz2 file compatibility. To achieve this format, use the ccoommpprreessss bbzziipp22:://// ffooppeenn wrapper built directly into PHP. intercept 0.2.0 Allows the user to request that a user-space function be called when a PHP function is executed. Support for class/object methods will be added later. mailparse 2.1.1 Mailparse is an extension for parsing and working with email messages. It can deal with rfc822 and rfc2045 (MIME) compliant messages. eZ publish 3.5.1 Ez.no announces the latest release of their content management system. From the announcement: ”eZ publish is an open source content management system and development framework. As a content management system (CMS) its most notable feature is its revolutionary, fully customiz- able, and extendable content model. This is also what makes it suitable as a platform for gener- al Web development. Its stand-alone libraries can be used for cross-platform, database independent PHP projects. eZ publish is also well suited for news publishing, e-commerce (B2B and B2C), portals, and corporate Web sites, intranets, and extranets. eZ publish is dual licenced between GPL and the eZ publish professional licence.” Get all the details from hhttttpp::////eezz nnoo// The Zend PHP Certification Practice Test Book is now available! We're happy to announce that, after many months of hard work, the Zend PHP Certification Practice Test Book, written by John Coggeshall and Marco Tabini, is now available for sale from our website and most book sellers worldwide! The book provides 200 questions designed as a learning and practice tool for the Zend PHP Certification exam. Each question has been written and edited by four members of the Zend Education Board the very same group who prepared the exam. The questions, which cover every topic in the exam, come with a detailed answer that explains not only the correct choice, but also the question's intention, pitfalls and the best strategy for tackling similar topics during the exam.

It is rather lit- tle known, however, that PHP supports a variety of archive formats, in various ways: PHP extensions that are compiled in (or loaded using pphhpp iinnii settings or ddll(()) ), PEAR packages and other external scripts. This article surveys the most important and relevant possi- bilities in this area, always with short examples that are ready-to-use for your applications. PHP Extensions From a performance point of view, using a PHP exten- sion is very often the best way to solve a problem. Since you’re dealing with compiled code, performance is usually much better than interpreted PHP code. However, not all of these extensions are updated on a frequent basis and some of them lack important fea- tures. But before judging, let’s first have a closer look. The file format that is probably most widely used over the Internet is the ZIP format, because it has been around for a long time and applications to manipulate it are widely available on all platforms. Recent versions of Windows come with an internal ZIP module, but do not support other formats out of the box; Linux distri- butions and Mac OS X offer much more in this respect. Therefore, in order to avoid the hassle of additional software installation, using the ZIP format is a good idea. There is even a PHP module that supports ZIP— you can find it in the online manual at hhttttpp::////pphhpp nneett//mmaannuuaall//eenn//rreeff zziipp pphhpp . The module is a wrapper for the ZZIPlib library, a SourceForge project available at hhttttpp::////zzzziipplliibb ssff nneett// . This library sup- ports only extracting data from an archive, not creating new ZIP files. Therefore, it can only be used with exist- ing ZIP files. Doing so, however, is relatively easy: first, you have to ensure that the PHP module is present. If you are building PHP by yourself, you have to run ccoonn ffiigguurree with the ——wwiitthh zziipp==//ppaatthh//ttoo//zzzziipplliibb switch; Windows users just need to add the following line to their pphhpp iinnii file: extension=php_zip.dll REQUIREMENTS PHP 4.x , 5.x OS Any Other Software The modules and packages refer- enced in the article.

PHP supports many of them, in different ways: using external PHP scripts, PEAR packages or PHP extensions.
