For example

    $contents = curl_exec ($ch);

Preg_match_all ("/(. *) <\/td>/", $contents, $arr);
for ($i =0; $i <=100; $i + +)
{

Print_r ($arr [1][$i]);
if (($i + 1)% 1 ==0)
{echo '
';}
}


I don't want to print $arr now, but put it in a string variable
------Solution--------------------
$txt = ";
for ($i =0; $i <=100; $i + +) {
$txt. = $arr [1][$i]);
if (($i + 1)% 1 ==0) {
$txt. = '
';
}
}
