PHP的str_replace无法正常工作？

Question

I am trying to do a simple task of storing an Email template into a Database, retrieving it and populating variables in the template before sending an email.

I am using str_replace but for some reason it is not working for me. To complicate it more, it works for 1 of my template variables below, the {{date}} one does get populated but all the others get skipped.

It is not an issue with my POST variables not being populated, I can even pass in a real text string in str_replace and it will still not find my "template variables" and replace them. Just the date one.

Any ideas why it would have such odd behavior? From what I can see, the Date one has nothing different?

Template

$admin_template = '<table>
    <tr>
      <td><strong>Name:</strong></td><td>{{name}}</td>
    </tr>
    <tr>
      <td><strong>Email:</strong></td><td>{{email}}</td>
    </tr>
    <tr>
      <td><strong>Website:</strong></td><td>{{website}}</td>
    </tr>
    <tr>
      <td><strong>Phone:</strong></td><td>{{phone}}</td>
    </tr>
    <tr>
      <td><strong>Source:</strong></td><td>{{source}}</td>
    </tr>
    <tr>
      <td><strong>Budget:</strong></td><td>{{budget}}</td>
    </tr>
    <tr>
      <td><strong>IP:</strong></td><td>{{{ip}}}</td>
    </tr>
    <tr>
      <td><strong>Date Submitted:</strong></td><td>{{date}}</td>
    </tr>
    <tr>
      <td><strong>Message:</strong></td><td>{{message}}</td>
    </tr>
  </table>';

Code to Process Template

// Process Admin Template
$admin_body = str_replace('{{name}}', $name, $admin_template);
$admin_body = str_replace('{{email}}', $mailFrom, $admin_template);
$admin_body = str_replace('{{phone}}', $_POST["phone"], $admin_template);
$admin_body = str_replace('{{website}}', $_POST["website"], $admin_template);
$admin_body = str_replace('{{message}}', $_POST["message"], $admin_template);
$admin_body = str_replace('{{budget}}', $_POST["budget"], $admin_template);
$admin_body = str_replace('{{source}}', $_POST["source"], $admin_template);
$admin_body = str_replace('{{ip}}', $_SERVER['REMOTE_ADDR'], $admin_template);
$admin_body = str_replace('{{date}}', date("Y-m-d H:i:s"), $admin_template);

Actual Output After Processing

// Actual Output...
<table>
<tr>
  <td><strong>Name:</strong></td><td>{{name}}</td>
</tr>
<tr>
  <td><strong>Email:</strong></td><td>{{email}}</td>
</tr>
<tr>
  <td><strong>Website:</strong></td><td>{{website}}</td>
</tr>
<tr>
  <td><strong>Phone:</strong></td><td>{{phone}}</td>
</tr>
<tr>
  <td><strong>Source:</strong></td><td>{{source}}</td>
</tr>
<tr>
  <td><strong>Budget:</strong></td><td>{{budget}}</td>
</tr>
<tr>
  <td><strong>IP:</strong></td><td>{{{ip}}}</td>
</tr>
<tr>
  <td><strong>Date Submitted:</strong></td><td>2013-05-26 05:01:14</td>
</tr>
<tr>
  <td><strong>Message:</strong></td><td>{{message}}</td>
</tr>
</table>

您一直在从头开始重新创建$admin_body ，放弃先前的str_replace()替换：-D
