To encrypt and decrypt text using AES/ECB/PKCS5Padding encryption algorithm, and pass data AES encrypted between PHP and Java. Two output types can be used in encryption and decryption: Base64, Hexadecimal.
AESUtil.java Dependencies & environment

Java Test Preview:
public static void main (String [] args) {
//AES only supports key sizes of 16, 24 or 32 bytes.
String key = "s+FZFDjBKMUVDpu=";
String plainText = "abcdef";
String ciphertextBase64 = AESUtil.encryptBase64(plainText,key);
String plaintextBase64 = AESUtil.decryptBase64(ciphertextBase64,key);
String ciphertextHexStr = AESUtil.encryptHexStr(plainText,key);
String plaintextHexStr = AESUtil.decryptHexStr(ciphertextHexStr,key);
System.out.println(ciphertextBase64);//output: /s9PA4KQBKUhRPJDp+v3UA==
System.out.println(plaintextBase64);//output: abcdef
System.out.println(ciphertextHexStr);//output: FECF4F03829004A52144F243A7EBF750
System.out.println(plaintextHexStr);//output: abcdef
