从mysql修复重新获得的路径

I have a problem with MySQL , that when I insert a path-to-a-directory in it , it automatically drops every '/' or '\' in the path string (which is apparently called canonized version of the path). when I retrieve the path using PHP I get something like this

C:wampwwwnamaCar_Images91Thumbs

Is there any PHP function that fixes this problem ? I want to use the retrieved path for the HTML image source but it doesn't work

Tnx
