Many in the open-sourced community have however been saying that there are still a lot of vulnerabilities with the system that uses code injection and many more that the many developers who have been developing and deploying it that remains to be fixed. Many of these target their AdSense links that is being used to boost rankings for bogus sites.

Soon after, PHP5.2.10 got it’s 2nd RC, news that 5.3 RC came out making an active few days in the lives of PHP developers.

Tips to simplify your life

Want to select multiple items from a list? Then you need to use the select multiple tag in HTML. The action handler then takes care of the form when the items are passed through it. What happens though, is that all of them are passed with the same widget name.

For example:
<select name=�var� multiple=�yes�>
The option you select will register with the action handler as var=option1, var=option2, var=option3. This thereby overwrites the previous $var variable’s contents.

The fix is to utilize the �array from form element� feature of PHP.

Use it like so:
<select name=�var[]� multiple=�yes�>
The first item then becomes $var[0], and then $var[1] for the next, and so on.

PHP is the most popular programming platform to ever grace the web and thanks to PHP, most of today’s web sites, blogs and many other internet staples are made possible with the use of PHP. Now one of the best news to come out of the PHP world is the announcement of the development of the Zend Server which would allow web application deployment and monitoring easy. This has been the most welcome news for till this, most systems have had to rely on the long used LAMP standard that worked but still relied on more traditional development methods that were labor intensive and quite hard to troubleshoot.
Zend promises to deliver faster development, deployment and bug fixing capabilities we can only dream of. (more…)

PHP version 5.2.7. is dangerous and a security hazard; take it out and update to 5.2.8. immediately:

Due to a security bug found in the PHP 5.2.7 release, it has been removed from distribution. The bug affects configurations where magic_quotes_gpc is enabled, because it remains off even when set to on. In the meantime, use PHP 5.2.6 until PHP 5.2.8 is later released.

The PHP Development Team would like to announce the immediate availability of PHP 5.2.8. This release addresses a regression introduced by 5.2.7 in regard to the magic_quotes functionality, which was broken by an incorrect fix to the filter extension. All users who have upgraded to 5.2.7 are encouraged to upgrade to this release. Alternatively you can apply a work-around for the bug by changing “filter.default_flags=0″ in php.ini.

Take out 5.2.7. as soon as possible and use the newest one for security’s sake!

What are the uses of Php in the whole computing thing? We might wonder. The answer is simple. Php is practically used everywhere. It is being adapted to multiple platforms. The scripting language has revolutionized the way we communicate within the internet. Php reads and writes files. It is used to execute basic directory and file monitoring and maintenance. Simply put, Php has enabled developers and programmers and users to do things that wasnt possible to do in the web the previous years, like editing specific documents and files remotely. It is used to search files. Collect them and for the information stored in that file to remain there and retrieve it when needed. Now, information is more accessible. It does not require to be coded to a certain database. It can generate HTML and PDF files. It can process XML for HTTP. Its amazing capability to function on different data source makes it the idela tool for search engines.

A reply line indicates whether a request was successful. It includes the protocol being used, a numeric status code, and a short description of the status code.

An example would be:

HTTP/1.1 200 OK

We often see numeric status codes in the browser every now and then. For so many reasons. These numbers may look jumbled to us or we simply cannot understand them but it stands for something.

The numeric status codes fall into the following ranges:

100-199
Information messages on the current status of processing.
200-299
Successful request.
300-399
Request cancelled because document or resource has been moved.
400-499
Client error. The request was incomplete, incorrect, or otherwise unresolvable.
500-599
Server error. Request appears valid, but server could not complete it.

Have you observed? The most common status message we get to see is the “404 Not Found” error, it just means that the document you requested does not exist. Two things though, this is either because it really doesn’t exist or because you entered the URL wrong. When a 404 is returned it is usually displayed on the browser screen in whatever default format is used by that browser. The server may also transmit a detailed error report page along with an error message if the resource call was unsuccessful.

PHP was created by Rasmus Lerdorf in 1994 and it was written in C programming language. He created PHP so that he can trace the people who visited his online CV. To make things easier for him to debug his program, he made it into an open source. Then, on June 8, 1995, Lerdorf combined PHP and his own Form Interpreter because of the growing needs of web pages. It was now called as PHP/FI, but generally known as PHP 2.0. Then, in 1997, Andi Gutmans and Zeev Suraski rebuilt the main parser. Before Andi Gutmans and Zeec Suraski rewrote the PHP’s core, PHP was widely known as “Personal Homepage”.

PHP was widely known as “Personal Homepage” until Andi Gutsman and Zeev Suraski Rebuit the main parser of PHP. And so, the acronym PHP was formally changed to PERL Hypertext Preprocessor. Then PHP 3 was released in 1998.

PHP 4 was released in May 2000 with a new core known as the Zend Engine 1.0. In July 2004, PHP 5 was released with the updated Zend Engine 2.0 and new features. PHP 6 was released in October, 20006.
