Convert java AES encryption code to php

I need the following code to me ported to php: import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; import [login to view URL]; public class Java_AES_Cipher { private static int CIPHER_KEY_LEN = 32; private static String CIPHER_NAME = "AES/CBC/PKCS5PADDING"; public static String encrypt(String paramString1, String paramString2, String paramString3) { try { if ([login to view URL]() < CIPHER_KEY_LEN) { int j = CIPHER_KEY_LEN; int k = [login to view URL](); int i = 0; for (;;) { localObject = paramString1; if (i >= j - k) { break; } paramString1 = paramString1 + "0"; i += 1; } } Object localObject = paramString1; if ([login to view URL]() > CIPHER_KEY_LEN) { localObject = [login to view URL](0, CIPHER_KEY_LEN); } paramString1 = new IvParameterSpec([login to view URL]("UTF-8")); localObject = new SecretKeySpec(((String)localObject).getBytes("UTF-8"), "AES"); Cipher localCipher = [login to view URL](CIPHER_NAME); [login to view URL](1, (Key)localObject, paramString1); paramString1 = [login to view URL]([login to view URL]([login to view URL]()), 0); paramString2 = [login to view URL]([login to view URL]("UTF-8"), 0); paramString1 = paramString1 + ":" + paramString2; return paramString1; } catch (Exception paramString1) { [login to view URL](); } return null; } }
