php - 由于php错误而没有显示任何内容

我刚刚开始学习PHP，所以最近我只是跟着一个教程，直到遇到此错误。php - 由于php错误而没有显示任何内容

与PHP只是它的方式，即使它在教程视频中完美地工作，页面也不显示任何内容。

我还发现了很多类似于我的问题，但我无法真正将它应用于我的代码。

无论如何，我要切入正题

这是代码

if ( !isset($_POST['fix_submit'])) { 

     $clickbait = strtolower $_POST["clickbait_headline"]; 

     // grab value from textarea in $_POST collection 
     // make all letters lowercase using strtolower() function 
     // store in a variable 

     $fake = array(
       "doctors", 
       "scientists", 
       "shocked me", 
       "won't believe", 
       "will never believe", 
       "hate" 
      ); 
     $replaceFake = array(
       "so-called doctors", 
       "so-called scientists", 
       "was like the others", 
       "will find normal", 
       "won't be surprised", 
       "aren't threatened by" 
      ); 

     $honestHeadline = str_replace ($fake, $replaceFake, $clickbait ); 

    }

整个误差是于第一线因为每当我删除的页面显示HTML但显然PHP不会工作。

编辑

修复那些语法错误后，固定无事的部分显示这样的帮助表示感谢。

现在它说

未定义指数：clickbait_headline上线8

，当我点击提交按钮没有任何反应无论如何，这是整个代码

<?php 

    define ("TITLE", "Honest Click Bait Headline"); 


    if ( !isset( $_POST['fix_submit'])) { 

     $clickBait = strtolower ($_POST["clickbait_headline"]); 

     // grab value from textarea in $_POST collection 
     // make all letters lowercase using strtolower() function 
     // store in a variable 

     $fake = array(
       "doctors", 
       "scientists", 
       "shocked me", 
       "won't believe", 
       "will never believe", 
       "hate", 
       "hack", 
       "simple" 

      ); 
     $replaceFake = array(
       "so-called doctors", 
       "so-called scientists", 
       "was like the others", 
       "will find normal", 
       "won't be surprised", 
       "aren't threatened by", 
       "common knowledge", 
       "well-known" 
      ); 

     $honestHeadline = str_replace ($fake, $replaceFake, $clickBait ); 
    }

死亡白屏：错误检查\显示已关闭，打开它们以查看错误。在你的php页面的顶部添加：'ini_set（'display_errors'，'On'）; ini_set（'html_errors'，0）; error_reporting（-1）;' – 2016-08-24 00:36:25

发布更多关于表格的代码 –

'strtolower'是一个函数，使用括号。 '$ clickbait = strtolower（$ _POST [“clickbait_headline”]）;'投票结束为错字。 – chris85

更换$clickbait = strtolower $_POST["clickbait_headline"];

与

$clickbait = strtolower($_POST["clickbait_headline"]);
