![]() Let’s go through the syntax of the base64_encode function.īase64_decode ( string $string, bool $strict = false ) : string | false Let’s go through each of these functions in detail. On the other hand, the base64_decode function is used to decode the MIME Base64-encoded data. The base64_encode function allows you to encode data in the MIME Base64 format. There are two main functions in PHP that deal with Base64 encoding. ![]() In the next section, we’ll discuss the built-in Base64 functions in PHP. It’s really easy to compare two Base64-encoded checksums for integrity. Firstly, you generate a hash with the help of a hashing algorithm like SHA, and then you convert the resulting hash into the Base64-encoded format to display it. Of course, you’re not supposed to use Base64 encoding itself to generate hashes, since it can be easily decoded. Specifically, Base64 is used for things like sending emails and uploading binary data in HTML forms.Īnother common use of Base64 encoding is hashing. This makes sure that the data remains intact while it’s transported. ![]() The primary use of Base64 encoding is to encode binary data to ASCII text, when you want to transfer such data over protocols that are specifically designed to handle textual data. Check out this primer on number systems and bases if you need a refresher. ![]() Effectively it represents the binary data in base 64 representation. Each character in the string represents six bits of information. What Is Base64 Encoding?īase64 is an encoding of binary data in ASCII. Basically, we’ll see how you could use PHP functions to transform data into the base64-encoded format. In this quick article, we’ll discuss the basics of base64 encoding in the context of PHP. ![]()
