PHP curl下载图片的方法

 
<?php
 

$images = [
 'http://wx.qlogo.cn/mmopen/vi_32/Q0j4TwGTfTKPkia3rxjuBoSQ1sUSmqYXDazibuIp8p2CCialBPjeYvcNJgky9P7hmlnDKgzX91utEQPu7VtsDqAIg/0',
];
function download($url, $path = 'dowloadceshi/2015-09-22_00-17-06j.png')
{
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
 $file = curl_exec($ch);
 
 curl_close($ch);
 $filename = pathinfo($url, PATHINFO_BASENAME);
 
 $resource = fopen($path, 'a');
 fwrite($resource, $file);
 fclose($resource);
}
 
foreach ( $images as $url ) {
 download($url);
}
?>

ps:如果采用file_get_contents方法发生图片下载过慢
