//// save an array as tab seperated text file//function write_tabbed_file($filepath, $array, $save_keys=false){  $content = '';  reset($array);  while(list($key, $val) = each($array)){    // replace tabs in keys and values to [space]    $key = str_replace("\t", " ", $key);    $val = str_replace("\t", " ", $val);    if ($save_keys){ $content .= $key."\t"; }    // create line:    $content .= (is_array($val)) ? implode("\t", $val) : $val;    $content .= "\n";  }  if (file_exists($filepath) && !is_writeable($filepath)){     return false;  }  if ($fp = fopen($filepath, 'w+')){    fwrite($fp, $content);    fclose($fp);  }  else { return false; }  return true;}//// load a tab seperated text file as array//function load_tabbed_file($filepath, $load_keys=false){  $array = array();  if (!file_exists($filepath)){ return $array; }  $content = file($filepath);  for ($x=0; $x < count($content); $x++){    if (trim($content[$x]) != ''){      $line = explode("\t", trim($content[$x]));      if ($load_keys){        $key = array_shift($line);        $array[$key] = $line;      }      else { $array[] = $line; }    }  }  return $array;}/*** Example usage:*/$array = array(  'line1' => array('data-1-1', 'data-1-2', 'data-1-3'),  'line2' => array('data-2-1', 'data-2-2', 'data-2-3'),  'line3' => array('data-3-1', 'data-3-2', 'data-3-3'),  'line4' => 'foobar',  'line5' => 'hello world');// save the array to the data.txt file:write_tabbed_file('data.txt', $array, true);/* the data.txt content looks like this:line1 data-1-1 data-1-2 data-1-3line2 data-2-1 data-2-2 data-2-3line3 data-3-1 data-3-2 data-3-3line4 foobarline5 hello world*/// load the saved array:$reloaded_array = load_tabbed_file('data.txt',true);print_r($reloaded_array);// returns the array from above
