Checking Deadlinks From the database manually is a Headache ,So why not use a script which return the http status of the particular link and tell us if the link is dead or not.So how do we check the dead links from the database ? How do we programatically check whether the link is dead or not ? To check broken or dead links from Database we will use curl .

Included in the post is a sample script that extracts the URLs from a field in the database (you'd need some extra smarts if you're pulling it from content) and running it though a "checklink" function. If the call to curl_getinfo returns false, the link is marked dead.

What feeds do the super star PHP/ JavaScript web developers subscribe to? What are the essential PHP/ JavaScript/ Web Development feeds? I have shared my fledgling list below. Many of these feeds were recommended by my friends at PHPWomen, others I somehow stumbled across myself and some I picked up from articles tweeted with the #linktuesday hashtag, which are aggregated here.

So far, the links include php|architect, Planet-PHP.net, the YUI blog, Matt Gemmell's blog and Evan Goer's blog. If you have others to share, be sure to leave them in the comments!

It is surprising to see how after all the code floating around people still find it hard to create random numbers. In a recent piece of code I encountered, the following was used to generate a string of random numbers. The code was written to provide a random string to be passed to a email verifier system - the type wherein a new user when he subscribes to a website needs to verify his email by clicking on a provided link.

He includes a snippet of the code that uses a call to str_shuffle on the set of numbers 1-10 to generate a random number. The only problem with the method is that, when the number gets large enough, PHP would automatically kick it into exponential format - not exactly ideal for an email link. Let this serve as a reminder for any scripts you might make that are similar.

I actually built this a few years ago because I had grandiose visions of becoming the next Google. Clearly, that did not happen, mostly because my localhost, database, and bandwidth are not infinite. Yet this little robot has quite interesting applications and uses if you really have the time to play with and fine-tune it.

You'll need to have cURL support built into your PHP installation to get the scripts working, but the actual code itself is pretty simple. Curl and XPath do most of the heavy lifting of finding and following the links and its easy enough to drop them into a MySQL table from there. You can download the source here.

In my last tutorial, 'A Better Login System', a few people commented on how they would like to see a tutorial on password recovery, which is something you don't always see in user access tutorials. The tutorial I am bringing you today will deal with just that. Using mySQLi, we will learn to recover unencrypted and (one-way) encrypted passwords.

They give you what you'll need to set up the database for the user information and the PHP code you'll need to connect to it and fetch the user's information. The script then generates an email with a custom link that will take the user to a page asking them to answer a security question before they can continue.]]> Wed, 06 May 2009 08:47:49 -0500 http://www.phpdeveloper.org/news/12387 http://www.phpdeveloper.org/news/12387 New on the TotalPHP blog today is this article talking about reading RSS feeds with PHP (more specifically with SimpleXML).

PHP 5's ability to read XML files is fantastically easy to use. In the past it was possible but it required quite a bit of long winded code to get any where. PHP 5's SimpleXmlElement function makes working with XML a breeze, and with much less code too!

They include a script as an example - five lines to completely parse and pull the title and link information out of the remote RSS file. The example creates a SimpleXML object using the feed's URL and makes each element inside accessible as an object (that can be looped through and properties can be checked on).

Perhaps one of the most frustrating aspects of using PHP with websites, is getting variables into CSS. Having variables stored in an ini file, config file or even a database can make the updating of the look and feel of a site simple, however, CSS files, by default, do not parse PHP. [...] A html file may also include a PHP file, in the same manner as it includes a CSS file. This means the stylesheet can be renamed from style.css to style.php.

Using this method, the PHP inside the file is parsed and, because its included with a link tag, the CSS is also made available to the rest of the page.

Forms needs a solid visual structure, a profound hierarchy of form elements (Fields and Labels), powerful techniques and Functionality (AJAX) to make the form look and work creatively. [...] Today we wanted to share with you some great steps to get the perfect form: we will go through designing and usability you need to keep in mind, styling your form, spicing it up with some nice javascript effects, validating user's input and finally getting it to work using PHP and Ajax.

Some of the links include:

Most of the article links also include links to demos of the tutorial/application in action.

A symfony project is made of one or more applications. Applications share nothing, but the model classes. But, even if the symfony documentation is crystal clear on the subject, many developers want to share more than just the model. The most requested feature being the ability to create links to a frontend application from a backend one.

This sort of linking is relatively simple in the 1.1 release of the framework - its instances of sfRoutingConfigHandler and sfPatternRouting that let you create the configuration classes (and code) to grab information and functionality from one application to another.
