Extracting values from an array?

brendonfeeley, thank you. I am not sure why but I keep getting the following error:

PHP Warning:  array_push() expects parameter 1 to be array, null given in /var/www/registryShowCli.php on line 19
PHP Warning:  array_push() expects parameter 1 to be array, null given in /var/www/registryShowCli.php on line 19

My code is as follows:

 $peer = implode("\n", $peer);//puts the whole thing in an array
 $row = explode("\n", $peer);//puts each line in an array
  print_r($row);
             for($i = 2; $i < sizeof($row); $i++){
                 if(strpos($row[$i], 'registrations.') !== false) {
                    break;
        }else{
                array_push($rows, $row[$i]);
        }
}

     print_r($rows);

Place this line before the loop:

$rows = array();

The array needs to exist before you can push to it.

You could also replace the array_push with the following:

$rows[] = $row[$i];

Thanks.
