Is converting a binary string to ASCII using bin2hex a recommended approach when dealing with encryption in PHP?

Converting a binary string to ASCII using bin2hex is not recommended when dealing with encryption in PHP, as it does not provide a secure way to handle binary data. Instead, it is better to use base64 encoding or functions specifically designed for encryption, such as openssl_encrypt.

// Secure way to convert binary string to ASCII using base64 encoding
$binaryString = "10101011";
$asciiString = base64_encode($binaryString);
echo $asciiString;
