Question

I have a question related to PHP. I am .net developer. I usually work on asp.net and c#.I installed Visual Studio and SQL Server in my laptop.Now I am trying to Install Xampp server on my system. Here I getting some problem.After Installation When it check for port. It show me message port 80 or 443 aleardy in use apache server installation is failed. I Guess it is happening due to IIS installed in my system. I stopped the IIS and Installed it again But the same problem is coming again. I uninstall the Skype too for this but nothing is working for me. Please tell me why this is happening and what is the solution for this. I hope you understand what is my problem. Please help me for this

Fix for this Problem:

Open up Skype and go to Tools and select Options. From the list that appears select Advanced and then Connection. There will probably be a check mark inside where it says “Use port 80 and 443 as alternatives for incoming connections” just unchecked that box and save your changes. Skype will still function normally and now XAMPP will be able to use port 80 to run.

if you have no Skype installed

• Locate the file httpd.conf. This file should be found in C:\xampp\apache\conf (or whichever directory you installed XAMPP.

• Open the file using a text editor.

• Locate the line that says Listen 80.

• Change the port number (80) to a different number(eg. 1234).

• Restart the Apache Server to have the change take effect. Do this
  by clicking on the Stop button on the XAMPP control panel and
  then clicking on the Start button.

• When you connect to the Apache Server, you will have to append
  the port number to the URL, previously where you typed localhost, you will now have to type localhost:1234
