警告：mysqli_query()期望參數(shù)1為mysqli，在我正在嘗試構(gòu)建一個(gè)簡(jiǎn)單的自定義CMS，但是我得到了一個(gè)錯(cuò)誤：警告：mysqli_query()期望參數(shù)1為MySQLi，在我為什么要犯這個(gè)錯(cuò)誤？我的所有代碼都是MySQLi，我使用的是兩個(gè)參數(shù)，而不是一個(gè)。$con=mysqli_connect("localhost","xxxx","xxxx","xxxxx");//check connectionif (mysqli_connect_errno($con)){echo "Failed to connect to MySQL:" .
mysqli_connect_error();}function getPosts() {$query = mysqli_query($con,"SELECT * FROM Blog");while($row = mysqli_fetch_array($query))
{
echo "<div class=\"blogsnippet\">";
echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
echo "</div>";
}}
