Answer 1

In the secound listing when you add " before and after the $imagepath why?
Remove this line $imagepathurl = '"'.$imagepath.'"'; and it should work:
$absolute = "\xampp\htdocs";
$relative = "http:\\localhost";
echo str_replace($absolute,$relative,$imagepath);
Update (Example what the line does)
$var = "MyString"; // Content of the String => MyString
$var = '"'.$var.'"'; // Content of the String => "MyString"

Use the function pathinfo to get an array as result with all the components of your path.
Then you can replace the part that you want to change and concatenate the path components again to get the desired new path.
The way commented in the other posts is just a string manipulation solution. If you want something safe when dealing with parsing paths you should use the php function pathinfo. If is some quite simple then the str_replace will do the work.

make sure that your database does not applies any character encoding on string if it applies any then first decode the sting value and then use this code.
$absolute = "C:\xampp\htdocs";
$relative = "http:\\localhost";
// if database contains encoded string decode first here
//creating absolute path for image (this will remove ./, ../ \, / to create operating system preferred path as windows uses \ and linuz user / as path separator )
$imagepathurl = realpath($imagepathurl);
// replasing absolute path to root directory with relative path
echo str_replace( $absolute , $relative , $imagepathurl);
