php - Google finance returns null -


i using curl retrieve value of current share price , have created several cron jobs update value of share every 20 minutes or so. yesterday working fine today returning null object , using curl value retrieval.

here code:

$sourceurl = 'http://www.google.com/finance/info?infotype=infoquoteall&q='.$row[1].':'.$main_id;      echo $sourceurl."<br/>"; $ch = curl_init(); $timeout = 5; // set 0 no timeout curl_setopt ($ch, curlopt_url, $sourceurl); curl_setopt ($ch, curlopt_returntransfer, 1); curl_setopt ($ch, curlopt_connecttimeout, $timeout); $sourcedata = curl_exec($ch); curl_close($ch); $json = str_replace("\n", "", $sourcedata);   //remove //, [ , ] build qualified string   $data = substr($json, 4, strlen($json) -5);

//decode json data

$json_output = json_decode(utf8_decode($data)); var_dump($json_output);

//output stock price //update_in_db returns query string in bottom

$query=update_in_db($json_output,$main_id); $result_query=mysqli_query($dbc,$query); if($result_query===false) {     echo mysqli_error($dbc)."<br/>"; } echo "done<br/>";`

this working fine said update_in_db reurns this:

update `stock_table` set `stock_curr_val`=0, `stock_change`=0, `stock_change_p`=0, stock_open_val`=0, `stock_hi_val`=0, `stock_low_val`=0, `stock_volume`='0', stock_hi_52`=0, stock_low_52`=0, `stock_market_cap`='0' `stock_symbol`='20microns';

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/...
