The most common methods are not terribly hard to learn and will help you to make better decisions on the legitimacy of a command or call seen on your network. Understanding the encoding methods threat actors use can help not only in everyday operations but importantly in cybersecurity and network security contexts. They are also widely used by malware authors to disguise their attacks and to implement anti-analysis techniques designed to frustrate malware hunters and reverse engineers. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.Īs you can see from that description, the way I'm using the PHP base64 encode and decode functions isn't exactly the intended use for these functions, but it does work very well, and I know many developers that use this technique whenever they run into this sort of problem.Encoded strings are everywhere and have many legitimate uses across the technology sector.

More PHP base64 encode and decode informationīefore leaving, here's some quick documentation from the PHP base64_encode function manual page:Įncodes the given data with base64. That's all there is to it, problem solved. decode the uri back to its original form Just use the PHP base64_decode function in the controller to convert the encoded string back to its original content with the base64_decode function, like this: If you encode a string on one end (the view), you'll need to decode it on the other end (the controller), and that's where the PHP base64_decode function comes in.Īgain, this is very simple.

In the case of my CakePHP problem, I used the PHP base64_encode function in my CakePHP view page, and encoded my URI string as shown in this CakePHP code snippet: In short, the PHP URL encode technique involves encoding a URL (or URI) before submitting it in an HTML form, and then decoding the URL after it has been received by whatever controller you are submitting your form to. PHP URL encoding - base64_encode to the rescue I knew I couldn't change the data, and I knew I needed to pass that URI string to the CakePHP controller, when I remembered my friend, the PHP base64_encode function, and the PHP URL encode technique. As you might guess by looking at it, trying to pass a raw URI string to a controller (with characters in it like the forward-slash character('/')) would have driven CakePHP nuts. In fact, because of the data at hand, the only thing I had was a string - and that string happened to be a URI (i.e., something like /foo/bar/baz).

But when I went to make the column a hyperlink, I realized I didn't have something like an id field I could use as a parameter to my CakePHP controller call. I was working on a CakePHP web application yesterday when I ran into an unusual problem: I was displaying data in a table in an index page, and I wanted to turn one of the columns of text into a hyperlink to a detail page.

PHP FAQ: Can you share an example of the PHP Base64 encode and decode functions?Įvery once in a while when you're working on a web application you'll run into data that can cause you some problems, and when that happens, the PHP base64_encode function can come to your rescue.
