php download picture hand batch document method of close Remotely pass meet need

近一直很忙,遇到一个手工活,需要下载一些远程的图片,一共一百多张,如果通过手工一张一张的保存,也太耗费时间了,于是上网google了一把,找到PHP批量下载图片文件的方法,原文是关于如何使用PHP批量下载CSS文件中的图片的文章。经过研究改写了一下就可以使用了,方便快捷多了。

PHP批量下载图片文件代码:

set_time_limit(0);//设置PHP超时时间
$imagesURLArray = array_unique($imagesURLArray );

foreach($imagesURLArray as $imagesURL) {
echo $imagesURL;
echo "
";
file_put_contents(basename($imagesURL), file_get_contents($imagesURL));
}

原理很简单,通过一个含有图片地址的数组循环,然后使用PHP的file_get_contents函数取得图片,在使用file_put_contents函数把图片保存下来。
P.S:一定要加上设置PHP超时时间哦~!

附上原文中通过php下载css中图片的代码:

$imagesURLArray = array_unique($imagesURLArray[1]);
foreach($imagesURLArray as $imagesURL) {
file_put_contents(basename($imagesURL), file_get_contents($imagesURL));
}
