广东话输出正确结果变量

Question

现在我尝试的结果追加到从MySQL查询PHP变量，这是所使用的代码：

<?php 
$con=mysqli_connect("localhost","root","","ezsnip"); 
// Check connection 
if (mysqli_connect_errno()) { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
} 

$result = mysql_query("SELECT Snip FROM snips WHERE ID='1'"); 

$row = mysql_fetch_array($result); 

$snip = $row['Snip']; 
$snip = str_replace('<?php', '&lt;?php', $snip); 
$snip = str_replace('?>', '?&gt;', $snip); 
?> 
    <div id="editor"><?php echo $snip; ?></div> 

当我运行的代码，它返回：mysql_fetch_array（ ）预计参数1是资源，在布尔C中给出：\ XAMPP \ htdocs中\ home.php上线

170行是：

$row = mysql_fetch_array($result);

您在创建mysqli资源后正在做mysql_query

<?php 
$con=mysqli_connect("localhost","root","","ezsnip"); 
// Check connection 
if (mysqli_connect_errno()) { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
} 

$result = mysqli_query($con,"SELECT Snip FROM snips WHERE ID='1'"); 

$row = mysqli_fetch_array($result); 

$snip = $row['Snip']; 
$snip = str_replace('<?php', '&lt;?php', $snip); 
$snip = str_replace('?>', '?&gt;', $snip); 
?> 
    <div id="editor"><?php echo $snip; ?></div>
