PHP's AES encryption algorithm complete Example _php technique

This example describes the AES encryption algorithm for PHP. Share to everyone for your reference, specific as follows:

<?php class MCrypt {private $hex _iv = ' 00000000000000000000000000000000 '; # converted JAVA byte code in to hex and Placed it here private $key = ' U1MJU1M0FDOUZ.QZ ';
    #Same as in JAVA function __construct () {$this->key = hash (' sha256 ', $this->key, True); echo $this->key. '
  <br/> ';
    function Encrypt ($str) {$td = Mcrypt_module_open (mcrypt_rijndael_128, ', MCRYPT_MODE_CBC, ');
    Mcrypt_generic_init ($TD, $this->key, $this->hextostr ($this->hex_iv));
    $block = Mcrypt_get_block_size (mcrypt_rijndael_128, MCRYPT_MODE_CBC);
    $pad = $block-(strlen ($STR)% $block);
    $str. = Str_repeat (Chr ($pad), $pad);
    $encrypted = Mcrypt_generic ($TD, $STR);
    Mcrypt_generic_deinit ($TD);
    Mcrypt_module_close ($TD);
  Return Base64_encode ($encrypted);
    function Decrypt ($code) {$td = Mcrypt_module_open (mcrypt_rijndael_128, ', MCRYPT_MODE_CBC, ');
Mcrypt_generic_init ($TD, $this->key, $this->hextostr ($this->hex_iv));    $str = Mdecrypt_generic ($TD, Base64_decode ($code));
    $block = Mcrypt_get_block_size (mcrypt_rijndael_128, MCRYPT_MODE_CBC);
    Mcrypt_generic_deinit ($TD);
    Mcrypt_module_close ($TD);
  return $this->strippadding ($STR);
    }/* for PKCS7 padding */Private Function addpadding ($string, $blocksize =) {$len = strlen ($string);
    $pad = $blocksize-($len% $blocksize);
    $string. = Str_repeat (Chr ($pad), $pad);
  return $string;
    Private Function strippadding ($string) {$slast = Ord (substr ($string,-1));
    $SLASTC = Chr ($slast);
    $pcheck = substr ($string,-$slast); if (Preg_match ("/$SLASTC {"). $slast.
      "}/", $string)) {$string = substr ($string, 0, strlen ($string)-$slast);
    return $string;
    else {return false;
    } function Hextostr ($hex) {$string = ';
    For ($i =0 $i < strlen ($hex)-1; $i +=2) {$string. = Chr (Hexdec ($hex [$i]. $hex [$i +1]));
  return $string; }} $encryption = nEW MCrypt (); echo $encryption->encrypt (' 123456 ').
"<br/>";

 echo $encryption->decrypt (' tpyxisj83dqes3uw8bn/+w== ');?>
