Grab Yahoo Stock Data streamerapi version

Method 1:

<?php
_grab_yahoo_stock_index_streamerapi_str('^DJI');

$STR = file_get_contents('tmp.txt');

$matchArr = NULL;

preg_match('/parent.yfs_u1f\((.*)\);/', $STR, $matchArr);

if (!empty($matchArr[1])) {
  $ARR = json_decode_v2($matchArr[1]);

  echo '
';
  print_r($ARR);
  echo '
';
}

function _grab_yahoo_stock_index_streamerapi($symbol) {
  $URL = 'http://streamerapi.finance.yahoo.com/streamer/1.0?s=' . $symbol;

  // l10 // index value
  // c10 // change value
  // p20 // change percentage
  // g00 // day range low
  // h00 // day rang high
  // v00 // volume
  $URL_field = '&k=c10,g00,h00,l10,p20,v00';

  $URL_postfix = '&callback=parent.yfs_u1f&mktmcb=parent.yfs_mktmcb&gencallback=parent.yfs_gencb';

  $URL = $URL . $URL_field . $URL_postfix;

  # When using CURLOPT_FILE, pass it the file handle that is open 
  # for write only (eg fopen('blahblah', 'w')). If you also open 
  # the file for reading (eg fopen('blahblah', 'w+')), curl will 
  # fail with error 23. 
  $fp = fopen('tmp.txt', 'w');

  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, $URL);

  # When you are using CURLOPT_FILE to download directly into a file 
  # you must close the file handler after the curl_close() otherwise 
  # the file will be incomplete and you will not be able to use it 
  # until the end of the execution of the php process.
  curl_setopt($ch, CURLOPT_FILE, $fp);

  curl_setopt($ch, CURLOPT_TIMEOUT, 3);

  //curl_setopt($ch, CURLOPT_VERBOSE, 1);

  curl_exec($ch);

  curl_close($ch);

  # at this point your file is not complete and corrupted.
  fclose($fp);

  return;
}

function json_decode_v2($json, $assoc = FALSE){
  $json = str_replace(array("\n","\r"), "", $json);

  //$str = preg_replace("/([a-zA-Z0-9_]+?):/" , "\"$1\":", $str); // fix variable names

  $json = preg_replace('/([{,])(\s*)([^"]+?)\s*:/', '$1"$3":', $json);

  return json_decode($json, $assoc);
}
?>

Method 2:
Set PHP curl option, but it doesn't work for me.

<?php
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
?>

Method 3:
Run this in command line (you need curl installed on your system):

curl -s -o - -N 'http://streamerapi.finance.yahoo.com/streamer/1.0?s=^DJI&k=c10,g00,h00,l10,p20,v00&callback=parent.yfs_u1f&mktmcb=parent.yfs_mktmcb&gencallback=parent.yfs_gencb'
