Sending SMS messages
Using Skype with PHP and Skype4COM
Now normally this is not a problem. I am one of those people who usually check their e-mail several times an hour, so I would get the notifications within about 15 minutes. More than fast enough for the particular website I was monitoring. However, another website which also lists accommodations has a much faster reading-rate. What is more, they have accommodations on a first-come-first-serve basis. Time really is of the essence when you want to get an appartment that way. Now it is fairly easy to get a PHP script to beep your PC speaker - just output the right character:
But my PC speaker is not very loud, and I will not hear it when I am in the next room, or listening to music. So in addition, my new script also sends me a text message whenever a last-minute accommodation becomes available. To do this, I used Skype, which offers a public API for just such needs.
Installing Skype4COM
The first step is to download Skype4COM. Extract the DLL file somewhere it can be found - for example, your windows/system32 directory. Check the properties and unblock it if you need to.
When you have succesfully extracted the Skype4COM dll, open a command line and navigate to the directory where you extracted it. Then, run regsvr32 to register it:
It should give you a notice that it succesfully registred Skype4COM.
Using Skype4COM in PHP
PHP offers a COM class to handle COM objects. The following example classes illustrate how you can use it to send an SMS message through Skype:
Using this class is fairly easy:
