How to use the base64_encode function in PHP?

In PHP, the base64_encode() function is used to encode a string in base64. This function is very simple to use, just pass the string you want to encode as a parameter. Here is an example:

$str = "Hello, World!";
$encoded_str = base64_encode($str);

echo $encoded_str;

In the example above, we encoded the string “Hello, World!” in base64 and printed the result. You can also save the return value of the base64_encode() function to a variable for use in later operations.
