Encrypted decryption-How does PHP implement the AES-256 encryption algorithm via OpenSSL?

The following script is provided from the shell script
Encryption command:

echo "xxxxxxxxxxxxxxxxxxxxxxxx" | openssl enc -aes-256-cbc -salt -k BCF2AEC59BD97C9D54D56FAAC1C48494 -base64

Decrypt command:

echo "xxxxxxxxxxxxxxxxxxxxxxx" | openssl enc -aes-256-cbc -salt -k BCF2AEC59BD97C9D54D56FAAC1C48494 -base64 -d

I know that PHP has provided the OpenSSL module, but I do not understand this module, I have no understanding of the friend, the above code is rewritten into PHP. Thank you so much.
