 $content_all=(string)$content_all;
str_replace("<b>", " ", $content_all);

As Marcoveccio answered, you actually do a str_replace, but you did not save the result. Therefore you did not what you wanted — Perrykipkerrie

If you want to remove html tag from a string you could go for strip_tags()

eg:

   <?php
   echo strip_tags("Hello <b>world!</b>");//Hello world
   ?>

Be careful strip_tag will remove all the tags from a string.

refer http://www.w3schools.com/php/func_string_strip_tags.asp.

one more thing if you use str_replace("", " ", $content_all); then it will give unwanted space

ie:str_replace("<b>", " ", "hi <br><br> vig");
result: hi      vig

You have to do it this way:

$content_all=str_replace("<b>", " ", $content_all);
$content_all=str_replace("</b>", " ", $content_all);

echo $content_all;

Of course, the last line is just an echo, so you can see the result.
