PHP downloads remote images to local through url_PHP tutorial

This article provides a paragraph about saving the image to this address through the image address from an ajax instance of mine. Here we read it directly through readfile and then save it through fopen

Example

/**
* Download to local through the remote url of the image
* @param: $url is the remote link to the image
* @param: $filename is the file name saved after downloading the image
​*/
function GrabImage($url,$filename) {
if($url==""):return false;endif;

ob_start();
readfile($url);
$img = ob_get_contents();
ob_end_clean();
$size = strlen($img);

//"../../images/books/" is the storage directory, $filename is the file name
$fp2=@fopen("../../images/books/".$filename, "a");
fwrite($fp2,$img);
fclose($fp2);

return $filename;
}
?>

The code is as follows

代码如下	复制代码
/** * 通过图片的远程url，下载到本地 * @param: $url为图片远程链接 * @param: $filename为下载图片后保存的文件名 */ function GrabImage($url,$filename) { if($url==""):return false;endif; ob_start(); readfile($url); $img = ob_get_contents(); ob_end_clean(); $size = strlen($img); //"../../images/books/"为存储目录，$filename为文件名 $fp2=@fopen("../../images/books/".$filename, "a"); fwrite($fp2,$img); fclose($fp2); return $filename; } ?>

Copy code

The function returns the name saved after downloading the image, then you only need to store the image directory + image name in the database. http://www.bkjia.com/PHPjc/631524.htmlwww.bkjia.comtrue
