Delete spaces php

Question

I need delete all tags from string and make it without spaces.

I have string

"<span class="left_corner"> </span><span class="text">Adv</span><span class="right_corner"> </span>"

After using strip_tags I get string

" Adv "

Using trim function I can`t delete spaces.

JSON string looks like "\u00a0...\u00a0".

Help me please delete this spaces.
