Question

我再一次寻求帮助。

我找到了这个停用词脚本 - 我基本上删除了一个字符串中的所有常用词。

<?php
$CommonWords = file_get_contents('http://localhost/stopwords.txt');
$CommonWords = explode("\n", $CommonWords);
$CommonWords = array_map('trim', $CommonWords); // <---- ADD THIS LINE
$keywords = 'The <meta> tag’s keyword attribute is not the page rank panacea it once was back in the prehistoric days of Internet search. It was abused far too much and lost most of its cachet. But there’s no need to ignore the tag. Take advantage of all legitimate opportunities to score keyword credit, even when the payoff is relatively low. Fill in this tag’s text with relevant keywords and phrases that describe that page’s content';
$search_keywords = strtolower(trim($keywords));$arrWords = explode(' ', $search_keywords);
$arrWords = array_unique($arrWords);
foreach ($arrWords as $word) {
 if (!in_array($word, $CommonWords) && (trim($word) != '')) 
 {
 $searchWords[] = $word;
 } 
 }
 print_r($searchWords);
 ?>

代码的输出如下所示：

Array ( [0] => [1] => tag’s [2] => keyword [3] => attribute [4] => page [5] => rank [6] => panacea [7] => prehistoric [8] => days [9] =>)

我如何格式化它以使输出如下所示:(没有数组和数字）

tag's, attribute, page, rank, panacea, prehistoric, days

Answer 1

在生成的数组上使用implode()。

$myString = implode( ', ', $myArray ); // Results in Item1, Item2, Item3, etc...

PHP print_r只显示数组而不是纯文本
