PHP - Echo and die - PHP - Echo and die

我实现了or die("message")打印消息并退出，但是我如何回显消息并退出?

$resolveGet = mysql_query($sqlGet) or exit("<span style='padding-left:10px;'>No results matching search term provided.</span>");

您的特定代码也可以以不同的方式编写，因为这里有一个逻辑或:

$resolveGet = mysql_query($sqlGet);
if (!$resolveGet ) {
    // exit("<span style='padding-left:10px;'>No results matching search term provided.</span>");
    // can rewrite this as 
    echo "<span style='padding-left:10px;'>No results matching search term provided.</span>";
   die(); // or exit;  // whatever
}
