on php document, made function. 

function getprices($url) {     global $pricelist;  // declare global . point of this.      $src = file_get_contents_curl($url);     $dom = new domdocument();     $selector = new domxpath($dom);     $results = $selector->query('//table/tr/td/span');      foreach($results $node) {         array_push($pricelist, $node->nodevalue);     } }

and bottom of page, called several.

$pricelist = array();  getprices("http://finance.naver.com/item/sise_day.nhn?code=005930"); getprices("http://finance.naver.com/item/sise_day.nhn?code=005930&page=2"); getprices("http://finance.naver.com/item/sise_day.nhn?code=005930&page=3");

and display it. 

echo $pricelist[1]; echo $pricelist[2]; echo $pricelist[3];

return in function, , 

$pricelist = getprices("http://finance.naver.com/item/sise_day.nhn?code=$code");

but don't know many scrapping case. please me...

you return partial results function , merge them complete results array.

<?php $result = [];  $result = array_merge($result, getsomevalues()); $result = array_merge($result, getsomevalues()); $result = array_merge($result, getsomevalues());  var_export($result);  function getsomevalues() {     static $i = 0;     // returning partial result of 3 elements     return [ $i++, $i++, $i++ ]; }

prints

array (   0 => 0,   1 => 1,   2 => 2,   3 => 3,   4 => 4,   5 => 5,   6 => 6,   7 => 7,   8 => 8, )
