mysql_close()期望参数1为资源，给定null
问题描述：
导致错误的行就是这个...
The line causing the error is this one...
mysql_close($con);
这是全部代码...
$con=mysqli_connect("localhost","root","pass","db_name");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM medicos");
while($row = mysqli_fetch_array($result)) {
echo '.....';
}
mysql_close($con);
答
必须将行mysql_close($con);更改为mysqli_close($con);
您不能互换使用mysql和mysqli函数，例如:
You cannot interchangeably use mysql and mysqli functions, for example:
mysqli_connect需要使用mysqli_close
-同样-
mysql_connect需要使用mysql_close
