Question

有很多解决方案可用于此错误，但似乎没有一个适用于我。我是一个新的PHP开发人员，并尝试使用PHP程序创建网站。

我得到的错误是＆＃34;警告：无法修改标头信息 - 已经发送的标头（/home/influss/public_html/Influsstest/hiremain.php:39中的输出开始）/ home /在第74行＆＃34;

上影响/ public_html / Influsstest / hiremain.php

我检查了行号。 39并且在php之前或之后找不到任何空格。程序的开头或结尾也没有空格，但我仍然收到此错误。

代码如下：

您不能在html输出后发送标头你必须把它们放在

之前

<!doctype html>

您可以使用以下方法解决此问题：

 <?php
 error_reporting(E_ALL); ini_set('display_errors', 'On');                
 function renderForm($id, $error)
 {
 if ($error != '')
 {
 $problems = '<div style="margin:0 200px;padding:4px; color:red ;font-weight:bold;">'.$error.'</div>';
                    }
 }
 include('connect.php');
 if (isset($_POST['submit']))
 { 
 $id = $_POST['regid'];
 $sql = "Select * from hirefinal where hr_id = '$id'";
 $result = mysql_query($sql) or die(mysql_error()); 
 $total_results = mysql_num_rows($result);
 if ($total_results > 0)
 {
 header('location:hireedit.php?regid='.$id);
 }
 else
 {
 $id = $_POST['regid'];
 $sql = "Select * from hirefinal where hr_id = '$id'";
 $result = mysql_query($sql) or die(mysql_error()); 
 $total_results = mysql_num_rows($result);
 if ($total_results > 0)
 {
 header("location:hireedit.php?regid=" . $id);
 }
 Else
 {                   
 $error = "Please register first";
 renderForm($id, $error);    
 }
 }
 mysql_free_result($result);
 }
 else
 {
 $error = "";
 $id=""; 
 renderform($id, $error);
 }
    ?>
