如何跳过PHP错误并呈现HTML的其余部分？

我用一个表单创建了一个联系人页面，问题是如果我发送了电子邮件，并且错误是由PHPmailer引起的，那么页面的其余部分不会呈现，但是如果是验证错误，那么整个页面就会呈现出应有的效果

不幸的是，我是在本地主机上运行的，所以我知道在发送时会有连接错误，但是在发现错误后，我如何才能使页面继续呈现

包含PHP文件的HTML：

include_once('validate.php');

除了包含的PHP文件之外，我知道将出现错误连接：

<?php
         $name = $srn = $email = $txt = "";
         $border1 = $border2 = $border3 = $border4 = "";
         $errornum1 = $errornum2 = $errornum3 = $errornum4 = 0;

         $errorname = $errorsrn = $errormail =  $errortxt =  $secondcap = "";

          function test_input($data) {
              $data = trim($data);
              $data = stripslashes($data);
              $data = htmlspecialchars($data);
              $data = preg_replace('/\s+/',' ', $data);
              return $data;
        }

        if($_SERVER['REQUEST_METHOD'] == 'POST'){

如果可能出现异常，请尝试以下操作：

try {

    if(!$mail->Send()){
        $secondcap = '<h3 style="color:#f00;text-align:center;">There Was an error sending your email please try again</h3>';
        return;
    }else{
        $secondcap = '<h3 style="color:#0f0">Your Email has been sent</h3>';
        return;
    }

} catch (Exception $e) {
    $secondcap = '<h3 style="color:#0f0">Your Email has been sent</h3>';
    echo $e->getMessage();
}

试试看{
如果（！$mail->Send（））{
$secondcap='发送电子邮件时出错，请重试'；
返回；
}否则{
$secondcap='您的电子邮件已发送'；
返回；
}
}捕获（例外$e）{
$secondcap='您的电子邮件已发送'；
echo$e->getMessage（）；
}
一些try-catch块怎么样？RTM：为什么在本地主机上运行应用程序时会出现问题？你为什么不把这些修好？
try {

    if(!$mail->Send()){
        $secondcap = '<h3 style="color:#f00;text-align:center;">There Was an error sending your email please try again</h3>';
        return;
    }else{
        $secondcap = '<h3 style="color:#0f0">Your Email has been sent</h3>';
        return;
    }

} catch (Exception $e) {
    $secondcap = '<h3 style="color:#0f0">Your Email has been sent</h3>';
    echo $e->getMessage();
}
