php：如何使用带有UTF8的strip_tags？

echo $src;

gives:

4960 MALMEDY

Then when I apply echo strip_tags($src);

gives me:

4960Â MALMEDY

The SPACE was replaced by  character:

What Do I do wrong ?

It looks that if I use

$src = utf8_decode($src); strip_tags works correctly.

Any rule I should know when to apply utf8_decode ?

please try this

   $text_top = strip_tags(trim(html_entity_decode($str,   ENT_QUOTES, 'UTF-8'), "\xc2\xa0"));
