替换PHP变量的内容（存储的HTML标签） [英] Replace Content for PHP Variable (HTML tags Stored)

问题描述

我想从PHP变量（ $ html_content c c ）...

I want to replace <a> tag contents from PHP Variable ($html_content)...

变量 $ html_content 值如下所示：

$html_content= "<table>
<thead>
<tr><th>Customer</th><th>Age</th><th>A</th></tr>
</thead>
<tbody>
<tr><td>Test 1</td><td>25</td><td><a href='www.google.com'>Link</a></td></tr>
<tr><td>Test 2</td><td>30</td><td><a href='www.yahoo.com'>Link</a></td></tr>
<tr><td>Test 3</td><td>31</td><td><a href='www.rediff.com'>Link</a></td></tr>
...
...
...
</tbody>
</table>

我要替换字符串中的内容每个最终< td> 每个< tr> 的内容包含< a& ; 标签。

I want to replace content in string every last <td> content of every <tr> which contains <a> tag.

样本行结果：

<tr><td>Test 1</td><td>25</td><td>Action will be taken soon.</td></tr>
<tr><td>Test 2</td><td>30</td><td>Action taken yesterday</td></tr>
...
...

我需要结果来替换每一行具有不同的内容值。内容取自表格。只有我想要替换的特定客户操作。

I need result to replace every row with different content values. The content is taken from table. The particular customer action only i want to replace.

CUSTOMER TABLE:
------------------------------------------------------
id    customer    age    action 
------------------------------------------------------
1     Test 1      25     Action will be taken soon
2     Test 2      30     Action taken yesterday
3     Test 3      31     Action will take tomw
4     Kumar       28     Suspended
...
...
...

------------------------------------------------------

使用此表格，我已将筛选结果显示在一个页面中，而无需执行描述，而不是< a> 标签。 （此结果是名为 reports.php 的页面的一部分）。
我想要导出这些记录只有使用操作字段描述到PDF（我使用HTML到PDF类）。
在该页面中，我已将这些HTML值发送到该页面，并存储在 export_pdf.php中的PHP Variable（ $ html_content ）中/ code> page ...

using this table i have shown filtered result in one page without action description instead of <a> tag. (This result is part of that page named reports.php). I want to export these records only with action field description to PDF(I'm using HTML to PDF class). In that page i had sent to these HTML values to that page and storing in PHP Variable($html_content) in export_pdf.php page...

表格记录是不是固定大小 ...它是基于生成排序的结果。

The table records is not fixed size... It's based on generating result from sorting.

请任何人帮助我...
提前感谢...

Please anyone help me... Thanks in advance...

推荐答案

请尝试以下代码：

$html_content= preg_replace("/<a[^>]+\>(.*?)<\/a>/i", "Action will be taken soon.", $html_content); 

使用 foreach 在查询

foreach($row = mysql_fetch_assoc($result))
{
    $html_content = preg_replace("/<a[^>]+\>(\w+)<\/a>/i", $row['action'], $html_content); 
}

输出

Output

<table>
   <thead>
      <tr><th>Customer</th><th>Age</th><th>A</th></tr>
   </thead>
   <tbody>
      <tr><td>Test 1</td><td>25</td><td>Action will be taken soon.</td></tr>
      <tr><td>Test 2</td><td>30</td><td>Action will be taken soon.</td></tr>
      <tr><td>Test 3</td><td>31</td><td>Action will be taken soon.</td></tr>
   </tbody>
</table>
