本文實例講述了C++加密解密php代碼的辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

#include "php.h"
#include "php_ini.h"
#include "ext/standard/info.h"
#include "string.h"

  RETURN_STRING(encode_code, 0);
}

  }

}

    if(offset == key_len){
      offset = 0;
    }
    * (code_encode + i) = * (code + i) ^ * (key + offset);
    offset ++;
  }
  return php_base64_encode(code_encode, code_len, &ret_len); //base64 加密
}
inline char * decode(char * code,long code_len, char* key, long key_len){
  char * code_decode;
  char * nobase_code;
  int i;
  long offset = 0, ret_len;
  zend_bool strict = 0;
  code_decode = strdup(code);
  nobase_code = php_base64_decode_ex((unsigned char*)code, code_len, &ret_len, strict); //解密，ret_len 前往長度
  for(i =0; i<ret_len; i++){
    if(offset == key_len){
      offset = 0;
    }
    * (code_decode + i) = * (nobase_code + i) ^ * (key + offset);
    offset ++;
  }
  * (code_decode + i) = '\0';
  return code_decode;
}
