| Treba mi chart od google charts. Posto se radi o mnogo podataka, a i korisnik moguce je da nema pristup do interneta (ima samo lokalno), treba server preuzeti chart i prikazati korisniku. Evo deo koda Code: header('Content-Type: image/png'); echo $this->chart->getChart(); ------------------------------------ public function getChart(){ return $this->_execute(); } private function _execute() { $ch = curl_init('http://chart.apis.google.com/chart?chid='.md5(uniqid(rand(), true)).'&'.http_build_query($this->_post)); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, count($this->_post)); curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($this->_post)); $response = curl_exec($ch); $file = fopen('/path/to/test/graph.png', 'w+'); fwrite($file, $response); fclose($file); return $response; } Ova skripta se nalazi na http://helpmenow.dalibor-sojic.info/adsl/graph $file = fopen('/path/to/test/graph.png', 'w+'); se nalazi u http://helpmenow.dalibor-sojic.info/test/ (graph.png) http://helpmenow.dalibor-sojic.info/test/difference.png je razlika izmedju graph.png (na skrinu pise grapn.txt) i fajl u pozadini (sa jedan red na pocetku visak) je resultat od Code: header('Content-Type: image/png'); echo $this->chart->getChart(); Odakle dolazi taj jedan red visak? Znaci... kad response snimim u fajl, sve je OK sa .png, a kad pokusam da prikazem response sa header funkciji, imam viska enter. |
