将 URL 与分隔的关键字关联起来

Question

我有一个变量 $keywords

这个变量的内容是用逗号或空格分隔的单词 例如：

$keywords= key1,key2,key3

或者

$keywords=key1 key2 key3

我拥有的表是：

        <table width="500" border="1">
  <tr>
    <td height='auto'>Keywords: $keywords</td>
  </tr>
</table>

我想在 key1 key2 key3 中爆炸 $keywords ... 并将每个分隔的单词关联到一个预定义的 URL：

http://miosite.com/search/label/key1
http://miosite.com/search/label/key2
http://miosite.com/search/label/key3

所以我想得到这个：

       <table width="500" border="1">
  <tr>
    <td height='auto'>Keywords: key1,key2,key3</td>
  </tr>
</table>

在哪里

        key1=http://miosite.com/search/label/key1
        key2=http://miosite.com/search/label/key2
        key1=http://miosite.com/search/label/key3

如何？

Answer 1

您可以检查逗号以确定要分解的分隔符，然后再次将字符串组合在一起：

if (strpos($keywords,",") !== FALSE) {
  $keys = explode(",",$keywords);
} else {
  $keys = explode(" ",$keywords);
}
$keywords = "";
foreach ($keys as $key) $keywords .= "http://miosite.com/search/" . $key . "<BR>";

编辑：显然目标是删除站点地址，而不是添加它......没有人知道这一点。新代码：

if (strpos($keywords,",") !== FALSE) {
  $keys = explode(",",$keywords);
} else {
  $keys = explode(" ",$keywords);
}
$keywords = "";
foreach ($keys as $key) $keywords .= str_ireplace("http://miosite.com/search/","",$key) . ",";
$keywords = substr($keywords,0,strlen($keywords)-1);

有点骇人听闻，但请尝试一下。

编辑：哦，现在他们需要链接吗？哈哈

if (strpos($keywords,",") !== FALSE) {
  $keys = explode(",",$keywords);
} else {
  $keys = explode(" ",$keywords);
}
$keywords = "";
foreach ($keys as $key) {
   $newkey = str_ireplace("http://miosite.com/search/","",$key);
   $keywords .= "<a href=\"" . $key . "\">" . $newkey . "</a>,";
}
$keywords = substr($keywords,0,strlen($keywords)-1);

好的，试试吧。

Answer 2

$keywords = explode(',',$keywords);
foreach($keywords as $key) echo("<a href=\"http://miosite.com/search/{$key}\">{$key}</a>");

Answer 3

关键词：

$keywords = explode(',',$keywords);
$tmpArray = array();
foreach($keywords as $key) {
    $tmpArray[] = 'http://miosite.com/search/label/'.$key;
}

echo implode(",", $tmpArray);

Answer 4

我只是在 html 和 html 中通过 embeddg php 重写。采取的是您的链接之间的逗号：

 <?php
$keywords = 'key1 key2 key3';
$keywords = preg_split('/[, ]/',$keywords);

foreach($keywords as $key)
    $links[]= "<a href=http://miosite.com/search/{$key}\>{$key}</a>";
    print_r($links);

$keywords  = implode(',',$links);   

?>

<table width="500" border="1">
  <tr>
    <td height='auto'>Keywords: <?php  echo $keywords ;?>
</td>
  </tr>
