PHP class for symmetric encryption algorithm

<?php
class Xcrypt{
    private $mcrypt;
    private $key;
    private $mode;
    private $iv;
    private $blocksize;
    public function __construct($key, $mode = 'cbc', $iv = "off"){
        switch (strlen($key)){
            case 8:
                $this->mcrypt = MCRYPT_DES;
                break;
            case 16:
                $this->mcrypt = MCRYPT_RIJNDAEL_128;
                break;
            case 32:
                $this->mcrypt = MCRYPT_RIJNDAEL_256;
                break;
            default:
                die("Key size must be 8/16/32");
        }

Asking for the use of PHP encryption and decryption algorithm

11 Jul 2016

A recent project requirement is to use PHP to generate an encrypted string from some ordinary information through an encryption algorithm. The encrypted string can parse out the previous information through the decryption algorithm (reverse). Since I have never done it before, I would like to ask friends here if they have any ideas for ready-made encryption and decryption algorithms. The algorithm needs to be complex enough and not easy to be cracked. It would be better if there is a specific code.
