Base32 encode and decode function in PHP
In PHP, you can use the base32_encode and base32_decode functions to encode and decode data in Base32 format. If you’re using PHP 5.6 or later, these functions are available by default.
The base32_encode function starts by converting each character in the input string to its ASCII value and then converts that ASCII value to an 8-bit binary representation. This results in a long binary string.
The base32_decode function starts by mapping each Base32 character in the input string to its 5-bit binary representation. This is done by finding the index of the character in the predefined set of Base32 characters.
Here’s an example:
Base32 Encode in PHP:
$data = "Hello, World!";
$encodedData = base32_encode($data);
echo "Encoded: $encodedData";Base32 Decode in PHP:
$encodedData = "JBSWY3DPEBLW64TMMQ======";
$decodedData = base32_decode($encodedData);
echo "Decoded: $decodedData";
