PHP8 实现 AES CBC PKCS5Padding 加密的问题

对方接口需要数据加密，java代码如下：

public class AESUtil {
    public final static String CHART_DEFAULT="UTF-8" ;
    private static String IVRANDOM = "0123456789ABEDEF";
    public static String enAES(String security,String key){
        try {
            byte[] content = security.getBytes(CHART_DEFAULT);
            byte[] aeskeys = key.getBytes(CHART_DEFAULT);
            Cipher  cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
            IvParameterSpec sp= new IvParameterSpec(IVRANDOM.getBytes(CHART_DEFAULT));
            SecretKeySpec spec = new SecretKeySpec(aeskeys,"AES");
            cipher.init(Cipher.ENCRYPT_MODE, spec,sp);
            byte[] context =   cipher.doFinal(content);
            return Base64.encodeBase64String(context);
        } catch (Exception e){
        }
        return null;
    }
   public static void main(String[] args) {
        String code = enAES("{\"text\":\"1234\"}","123456781234567812345678");
        System.out.println("加密后的密文："+code);
    }
}

php 里用openssl_encrypt 试了很多种都不行，对应的php应该怎么写呢，帮帮忙，谢谢！
