str_replace for br标签不起作用

Question

I have a textarea field on a form that a user submit and it gets saved to a MySQL database. When I retrieve the value, I'm running nl2br to convert the line breaks to br tags. Then I'm using str_replace to replace the double br's with p tags. The issue is nothing is being replaced. I've looked at this over and over and just can't figure out what could be wrong.

Here's the HTML output:

Windows XP Home / Professional
<br />(32 and 64 bit)
<br />
<br />Test Operating System 2
<br />(32 and 64 bit)
<br />
<br />Test Operating System 3
<br />(64 bit)

Here's my PHP:

$FORMATTED = str_replace("<br /><br />", "</p><p>", $SUPPORTED_PLATFORMS);

The output of $FORMATTED looks exactly the same as the HTML output above. I essentially want to replace all the back to back br tags with the p tag and leave all the single br tags the way they are.

Thank you!!

The problem is, that you are trying to replace <br /><br /> string, but this string is not in your source. There is <br /> <br /> or <br /> <br />
