我可以将 php 中的变量发送到另一个页面吗？

Question

This is my code but it doesn't work (error 500)

while ($dbarr = mysqli_fetch_array($result))    
{
    echo $dbarr['qno']; 
    echo '<a href=show_detail.php?item=' . $dbarr[qno] . '>' . $dbarr[ans] . '</a>';
    
    echo $dbarr['qname'],"</a>&nbsp;";      
    echo $dbarr['qcount'] . "<br>\n";   

}

Answer 1

Error 500 is often caused by an error in the PHP code.

Google for enable php error logging .

error_reporting(E_ALL);

Check if $dbarr contains the expected keys:

while ($dbarr = mysqli_fetch_array($result))    
{
    print_r($dbarr);
}
