PHP到XML - 替换/修剪特殊字符

How do I replace ” into " in my php code?

Current XML output (Partial)

<content type="html"><![CDATA[<p style="text-align: justify;">Lorem Ipsum is simply dummy text of the printing and typesetting industry.

<p style="text-align: justify;"><br style=”clear:both;”/>Lorem Ipsum is simply dummy text of the printing and typesetting industry.

<p style="text-align: justify;"><br style=”clear:both;”/>Click <a href="http://www.google.com/" target="_blank">here</a> for more information.]]></content>

As you can see there is ” wrapping clear:both; style. All I want is replace it to ".

My PHP Code (not working)

<content type="html"><![CDATA[<?php echo str_replace("\”","",$row["content"]); ?>]]></content>

PS: The ” already inside database.
Update:

If you test on your server with

    <?php

    $data = "<a style=”clear:both;”></a>";

    echo str_replace('”','"',$data);

    ?>

Output : "clear:both;"

It will never work.

But if you try with

    <?php

    $data = "”clear:both;”";

    echo str_replace('”','"',$data);

    ?>

Output : nothing

It's working! But I want it work within tag....

I've just tested, and the following is working fine for me:

<?php echo str_replace ( '”','"', $row["content"] ); ?>

I'm replacing ” with ".

Edit: Replace the quotes in your source or if not possible, before you insert it to your database.

<?php
    $value = '<p style="text-align: justify;"><br style=”clear:both;”/>Click <a href="http://www.google.com/" target="_blank">here</a> for more information.]]></content>';

    echo $value;
    echo str_replace("”","\"",$value)
?>

str_replace ( "”","\"", $row["content"] ); In you're case.
