PHP Create a string with predefined column and width












2















I have a standard data like this:



+------------+----------+-------+
| name | position | width |
+------------+----------+-------+
| REFERENCE | 20 | 9 |
| TRNSXN | 48 | 14 |
| ESTIM_DATE | 64 | 8 |
+------------+----------+-------+
3 rows in set (0.00 sec)


My goal is to create a string where I can define the position and the width of each element, something like this



                   ETL                         E7954           20181123


As you can see
first string is REFERENCE = "ETL"; starts on 20 and has a maximum 9 characters. if it has less, put space at the rest.



Then second string is TRNSXN = E7954; is start on 48 and have maximum 14 characters, if it has less, put space at the rest. So on, so on.



So far, this is my code:



private function preFormattedText($string, $width)
{
return str_pad($string, $width, " ", STR_PAD_RIGHT);
}

public function actionHermesAnsi($id)
{
$modelWestims =getDataAsAboveDescription ;


$stringWestim = null;
$stringWestim .= $this->preFormattedText('ETL', (int)$modelWestims[0]['width']);
$stringWestim .= $this->preFormattedText('E7954', (int)$modelWestims[1]['width']);

header("Content-type: text/plain");
header("Content-Disposition: attachment; filename=westim.txt");

print $stringWestim;
exit();
}


I got ETL E7954
I can not define the position of it. Please help.

          Something like this will do what you want:



          function formatStrings($strings, $positions) {
          $position = 0;
          foreach ($strings as $key => $str) {
          // do we need to move to a new position to display the next string?
          if ($positions[$key]['position'] > $position) {
          echo str_pad('', $positions[$key]['position'] - $position - 1);
          $position = $positions[$key]['position'];
          }
          // display the string
          echo str_pad($str, $positions[$key]['width']);
          $position += $positions[$key]['width'] - 1;
          }
          }

          $strings = array('ETL','E7954','20181123');
          $positions = array(array('position' => 20, 'width' => 9),
          array('position' => 48, 'width' => 14),
          array('position' => 64, 'width' => 8));
          echo formatStrings($strings, $positions);

            Maybe you can use STR_PAD_LEFT with the position like you did with the width, and remove the length of $stringWestim :



            private function preFormattedText($stringWestim, $string, $width, $position)
            {
            $string = str_pad($string, $position - strlen($stringWestim), " ", STR_PAD_LEFT );
            return str_pad($string, $width, " ", STR_PAD_RIGHT);
            }

              Thanks for @Nesku and @Nick.



              I use Nick's answer, a little modification based my needs like this:



              private function formatStrings($strings, $positions)
              {
              $position = 0;
              $returnString = null;
              foreach ($strings as $key => $str) {
              // do we need to move to a new position to display the next string?
              if ($positions[$key]['position'] > $position) {
              $returnString .= str_pad('', $positions[$key]['position'] - $position - 1);
              $position = $positions[$key]['position'];
              }
              // display the string
              $returnString .= str_pad($str, $positions[$key]['width']);
              $position += $positions[$key]['width'] - 1;
              }

              return $returnString;
              }

                        Maybe you can use STR_PAD_LEFT with the position like you did with the width, and remove the length of $stringWestim :



                        private function preFormattedText($stringWestim, $string, $width, $position)
                        {
                        $string = str_pad($string, $position - strlen($stringWestim), " ", STR_PAD_LEFT );
                        return str_pad($string, $width, " ", STR_PAD_RIGHT);
                        }
