How to send asynchronous requests in PHP
It’s easy to make asynchronous calls in PHP with just a little bit of HTTP header knowledge and some library code around PHP sockets. This technique is useful when posting requests to your own server for bits of logic you’d like to run in the background. If you don’t control the endpoint, you might not be comfortable with some of the limitations, such as the inability to read anything from the response. So, you couldn’t post data to a we...

Turn browser into notepad with one line of code
This is the code shared by Jose on codewall. When you type data:text/html, into the address bar of the browser and press enter, the browser will turn into a notepad which you can edit. Why it works?

Otherwise, a popup blocker would show on the browser address bar which indicates that something is blocked. To workaround this issue, normally you should implement the window open logic in a click e...
