组合并添加到php变量

I am trying to combine some php variables to get the full path to a file.

$filepath and $file are working variables. I want the combined variable to be like > filepath/file.xml

$get = file_get_contents( $filepath '/' $file '.xml');

this is what I have and does not work.

Add concatenate of both $filepath and $file

$get = file_get_contents( $filepath.'/'.$file.'.xml');

Use this code:

You are missing . for concatenate.

$get = file_get_contents( $filepath.'/'.$file.'.xml');

if you want to combine the path, don't forget using predefined constants DIRECTORY_SEPARATOR (slash or back slash according with your system) and concatenate it with "."

$DS = DIRECTORY_SEPARATOR;  
$get = file_get_contents( $filepath.$DS.$file.'.xml');
