2. 3 methods for PHP to download remote images
This article demonstrates three methods of downloading images from remote URLs and saving them to local files, including file_get_contents, curl and fopen.
##
//1. 使用file_get_contents function dlfile($file_url, $save_to) { $content = file_get_contents($file_url); file_put_contents($save_to, $content); } //2.使用CURL function dlfile($file_url, $save_to) { $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 0); curl_setopt($ch,CURLOPT_URL,$file_url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $file_content = curl_exec($ch); curl_close($ch); $downloaded_file = fopen($save_to, 'w'); fwrite($downloaded_file, $file_content); fclose($downloaded_file); } //3.使用fopen function dlfile($file_url, $save_to) { $in= fopen($file_url, "rb"); $out= fopen($save_to, "wb"); while ($chunk = fread($in,8192)) { fwrite($out, $chunk, 8192); } fclose($in); fclose($out); }
