仅在不超过2天的情况下卷曲下载图像
我想从远程服务器下载图像，只要它不超过两天。
我正在运行的代码是否正确？我想在下载之前知道
last_modified
$ch = curl_init($file_source); // the file we are downloading
curl_setopt($ch, CURLOPT_TIMEOUT, 20);
curl_setopt($ch, CURLOPT_FILE, $wh);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_FILETIME, true);
curl_exec($ch);
$headers = curl_getinfo($ch);
$last_modified = $headers['filetime'];
if ($last_modified != -1) { // unknown
echo date("Y-m-d", $last_modified); //etc
}
curl_close($ch);
fclose($wh);

$file_source = 'http://www.google.com/images/nav_logo29.png'; $ch = curl_init($file_source); curl_setopt($ch, CURLOPT_TIMEOUT, 20); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_FILETIME, true); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, false); <-- don't download first curl_exec($ch); $headers = curl_getinfo($ch); $last_modified = $headers['filetime']; if ($last_modified != -1) { if ($last_modified>time()-86400*2) <-- not older than 2 days { $ch2 = curl_init($file_source); $wh = fopen('YOUR_PATH, 'w'); curl_setopt($ch2, CURLOPT_FILE, $wh); curl_exec($ch2); curl_close($ch2); fclose($wh); } } curl_close($ch);
