PHP格式化文本文件

Question

How can I format a text file that the content looks like this:

Col 1     Col 2     Col 3    ...
abcd      ab        a
ab        a         abcd

Each string have a different length.

The output I have reached with my PHP code looks quite ugly:

Col 1     Col 2     Col 3    ...
abc   abc   abc
abc      abc        abc

My PHP code to create the text file follows:

$tab = "\t\t";
$txtString = "";
foreach ($teams->get() as $team) {
    $class = $classes->getClasses($team["class_id"]);
    $club = $clubs->get($team["club_number"]);
    $txtString .= $class[0]["class_name"] . $tab;
    $txtString .= $team["club_number"] . " " . $club[0]["name"] . $team["team_number"] . $tab;
    $txtString .= $team["team_leader_name"] . $tab;
    $txtString .= $team["team_leader_street"] . $tab;
    $txtString .= $team["team_leader_place"] . $tab;
    $txtString .= $team["team_leader_phone"] . "
";
}

$file = "Mannschaftsfuehrer.txt";
file_put_contents($file, $txtString);

Can anyone help me to get a well formatted text file? Thanks in advance.

If you compare with sprintf execution time is quite low.& spaces can be changed. SO i prefer using my own function.

Here is a function which returns you string with enough spaces. Here str is string you want to format.

 function getFormatted($str,$col_width){
  $n=$col_width-strlen($str);
  for(;$n>0;$n--)
  $str.=' ';
  return $str;
}
