sim900a可以直接访问数据库吗

$conn=mysql_connect("localhost", "root", "")

mysql_select_db("dzsw",$conn)

$link = mysqli_connect("localhost", "root","","dzsw")

if (!$link) {

echo "Connect failed: ", mysqli_connect_error()

exit()

}

void UDP_Receive(void *arg, struct udp_pcb *upcb, struct pbuf *p,

struct ip_addr *addr, u16_t port)

{

uint8_t i=0

struct ip_addr destAddr = *addr

if(p != NULL) /* 如果收到的数据不为空 */

{

//pbuf_copy_partial(p, UDPData, p->len, 0)

udp_sendto(upcb,p,&destAddr,port) /* 将收到的数据再发送出去 */

pbuf_free(p) /* 释放缓冲区数据 */

}

}
