2 – Get download speed of your webserver

Do you ever wanted to know the exact download speed of your webserver (or any other?) If yes, you’ll love that code. You just have to initialize the $url variable with any resources from the webserver (images, pdf, etc), place the file on your server and point your browser to it. The output will be a full report of download speed.

4 – Publish a post on your WordPress blog, using cURL

I know that most of you enjoy WordPress, so here is a nice “hack” as the ones I regulary publish on my other blog WpRecipes.
This function can post on your WordPress blog. You don’t need to login to your WP dashboard etc.
Though, you must activate the XMLRPC posting option in your WordPress blog. If this option isn’t activated, the code will not be able to insert anything into WordPress database. Another thing, make sure the XMLRPC functions are activated on your php.ini file.

5 – Test the existence of a given url

I know, it sounds basic. In fact, it is basic, but it is also very useful, especially when you have to work with external resources.

In a previous article, I have discussed how spammers spams your WordPress blog. To do so, they simply have to fill the $postfields array with the info they want to display and load the page.
Of course, this code is only for educationnal purposes.

8 – Get feed subscribers count in full text

If you’re a blogger, you’re probably using the popular FeedBurner service, which allo you to know how many people grabbed your rss feed. Feedburner have a chicklet to proudly display your subscriber count on your blog. I personally like the chicklet’s look, but I heard lots of bloggers complaining about it. happilly, cURL can simply grab the count value and return it to you as a variable so you can display it as you want on your blog.

9 – Get the content of a webpage into a PHP variable

This is a very basic thing to do with cURL, but with endless possibilities. Once you have a webpage in a PHP variable, you can for example, retrieve a particular information on the page to use on your own website.
