PHP standard AES Encryption algorithm class

Share a standard PHP AES cryptographic algorithm class, where Mcrypt_get_block_size (' rijndael-128 ', ' ECB '), if it is easier to make a mistake if you do not understand the principle, you can pass the Mcrypt_list_ The algorithms function looks at the identity of the cryptographic algorithm you need.
