  This simple PHP function merges an array of directory or file names, to compose a full pathname, if any of the elements of the array contain superfluous directory separators, doubled separators are merged into one.
  

  
      <?php
      function make_path_from_bits() {
          //Accepts $sep (separator, eg "/"), followed by the filenames.
          $bits = func_get_args();    // all the arguments into an array
          $sep = array_shift($bits);  // arg1 is the separator, the rest are the files
          $p = implode($sep,$bits);
          $double = $sep . $sep;
          while (strpos($p,$double) !== false) {
              $p = str_replace($double, $sep, $p);
          }
          return $p;
      }
  

  
  Example of usage:
  

  
  $webroot = "/";
  $myfile = "/styles/my.css";
  $data = "data/"
  
  $fullpath = make_path_from_bits("/",$webroot,$data,$myfile);
  echo $fullpath;
  

  
  …gives the result:
  /data/styles/my.css
