Code PHP and details variable

[JS]
lib: https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/crypto-js.js
Variable:
var salt = 'salt'; //salt
var iv = '1111111111111111'; //pass salt minimum length 12 chars
var iterations = '999'; //iterations

//--functions
function getKey(passphrase, salt) {
    var key = CryptoJS.PBKDF2(passphrase, salt, {
        hasher: CryptoJS.algo.SHA256,
        keySize: 64 / 8,
        iterations: iterations
    });
    return key;
}

function userJSEncrypt(passphrase, plainText) {
    var key = getKey(passphrase, salt);
    var encrypted = CryptoJS.AES.encrypt(plainText, key, {
        iv: CryptoJS.enc.Utf8.parse(iv)
    });
    return encrypted.ciphertext.toString(CryptoJS.enc.Base64);
}

function userJSDecrypt(passphrase, encryptedText) {
    var key = getKey(passphrase, salt);
    var decrypted = CryptoJS.AES.decrypt(encryptedText, key, {
        iv: CryptoJS.enc.Utf8.parse(iv)
    });
    return decrypted.toString(CryptoJS.enc.Utf8);
}
