Question

我知道 or die("message") 打印消息并退出，但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>");

Answer 1

您的特定代码也可以以不同的方式编写，因为您所拥有的是合乎逻辑的或 :

$resolveGet = mysql_query($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
}

PHP - 回声然后死去

PHP - Echo and die
