Simple AES encryption and decryption algorithm implemented in PHP

This article mainly introduces the simple AES encryption and decryption algorithm implemented by PHP, and analyzes the related operation skills of PHP for string encryption and decryption based on mcrypt_encrypt, bin2hex, mcrypt_decrypt and other methods based on specific examples. Friends in need can refer to the following

The example in this article describes the simple AES encryption and decryption algorithm of PHP. Share it with everyone for your reference, the details are as follows:

/*
* 实现AES加密
* $str : 要加密的字符串
* $keys : 加密密钥
* $iv : 加密向量
* $cipher_alg : 加密方式
*/
function ecryptdString($str,$keys="6461772803150152",$iv="8105547186756005",$cipher_alg=MCRYPT_RIJNDAEL_128){
  $encrypted_string = bin2hex(mcrypt_encrypt($cipher_alg, $keys, $str, MCRYPT_MODE_CBC,$iv));
  return $encrypted_string;
}
/*
* 实现AES解密
* $str : 要解密的字符串
* $keys : 加密密钥
* $iv : 加密向量
* $cipher_alg : 加密方式
*/
function decryptStrin($str,$keys="6461772803150152",$iv="8105547186756005",$cipher_alg=MCRYPT_RIJNDAEL_128){
  $decrypted_string = mcrypt_decrypt($cipher_alg, $keys, pack("H*",$str),MCRYPT_MODE_CBC, $iv);
  return $decrypted_string;
}
