replace .$example=$_GET['t']; $example itself a be array. you can process it as you need

  if (isset($_GET['submit'])) {
    $example[] = $_GET['t'];

    echo $example . 'chk';
}

to

  if (isset($_GET['submit'])) {
      $example = $_GET['t'];

      for($i=0;$i<sizeof($example);$i++){
          echo $example[$i]."<br>";
      }

  }

or you can use foreach also

if (isset($_GET['submit'])) {
    $example = $_GET['t'];
    foreach ($example as $value) {
        echo "$value <br>";
    }
}

A `foreach` would be better that a `for` loop then size does not matter – RiggsFolly Jan 10 '16 at 11:22
@RiggsFolly yes you can go for foreach also. i edit foreach also now – Vigneswaran S Jan 10 '16 at 11:23
Also you would need to do `echo $example[0][$i];` as you have coded it. Asuming `$_GET['t']` was the first thing placed in the `$example` array – RiggsFolly Jan 10 '16 at 11:24
@RiggsFolly echo $example[0][$i]; it is not required .echo $example[$i]; is enough. $example =$_GET['t']; is a 1D array – Vigneswaran S Jan 10 '16 at 11:26
@Malik happy to help you :) – Vigneswaran S Jan 10 '16 at 11:36
