PHP - 回声和死亡

Question

我意识到or die("message")会打印邮件并退出，但如何回复邮件并退出？

$resolveGet = mysql_query($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采用不同的方式编写，因为您拥有的代码是逻辑或：

$resolveGet = mysql_query($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
}
