for循环的每次迭代期间显示输出

Question

我想在php中显示一条消息，显示for循环的每次迭代的结果。

我已经尝试了几种使用jquery，ajax等的方法，但它们似乎不符合我的需要，或者我不能解决它们。

我的脚本做了什么？

它扫描网站，抓取一些链接，然后逐个访问每个链接并从每个页面抓取图像，最后将其发送到我的wordpress包括其标题和图像。

有什么问题？

问题在于，因为可能有多个链接（超过200个），所以即使我的脚本显示有关成功的消息，但它会在整个循环执行完毕后显示消息。

我想做什么？

现在，我想在每次迭代期间做到这一点，消息应该显示在浏览器上，而不是等待循环完成，即在第一次迭代（发布成功），然后在第二次（未发布）等等。

以下是代码：

<?php

$category = array();

for ($i = 0; $i < count($result); $i++)
{
  set_time_limit(30);

  // Check if post already exists
  global $wpdb;
  $query = $wpdb->prepare('SELECT ID FROM ' . $wpdb->posts .
     ' WHERE post_name = %s',sanitize_title_with_dashes($result[$i]->title));
  $cID = $wpdb->get_var($query);

  if (!empty($cID))
  {
     echo $result[$i]->title .
         " <font style='color:#FF0000; font-weight:bold;'>Already Exists.</font><br />";
  } else
  {
     $inner_html = file_get_html($result[$i]->href);

     $inner_result_image = $inner_html->find('meta[property=og:image]',1);
     $inner_result_cats = $inner_html->find('a[rel=category tag]');

     $title = $result[$i]->title;
     $body = "<a href='$inner_result_image->content'><img src='$inner_result_image->content' /></a>";

     // Automatically Create new Category if it doesn't exist.

     foreach ($inner_result_cats as $cats)
     {
         if (!($cats->innertext == "Jobs"))
         {

             array_push($category,$cats->innertext);

             $count = 0;

             // For Cities
             if (search_city($cats->innertext))

                     'description' => '',
                     'slug' => '',

             } else

                 $count += 1;
             }

             }

             if (check_international(parse_url($cats->href,PHP_URL_PATH)))
