Can PHP be used to encrypt data?
PHP encryption is important to the privacy and safety of your data. In practical terms, PHP encryption uses algorithms (sometimes called hashing algorithms) to translate the “clear” data into encrypted text that requires very specific decryption processes to “decode” the data back to the clean version.
