css file php put download introduce code and picture accomplish us batch document

Let’s first introduce the methods of batch downloading image files in PHP and images in CSS. We will use the file_put_contents() function for this. Let’s look at the first batch download of images.

代码如下	复制代码
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));

} The principle is very simple, loop through an array containing the image address, then use PHP's file_get_contents function to obtain the image, and then use the file_put_contents function to save the image.
P.S: Be sure to set the PHP timeout~!

Attached is the code for downloading images in css through php in the original article:

The code is as follows

Copy code

代码如下

复制代码

//note 设置PHP超时时间

//note 取得样式文件内容
$styleFileContent = file_get_contents('images/style.css');

//note 匹配出需要下载的URL地址
preg_match_all("/url((.*))/", $styleFileContent, $imagesURLArray);

//note 循环需要下载的地址，逐个下载
$imagesURLArray = array_unique($imagesURLArray[1]);
foreach($imagesURLArray as $imagesURL) {
file_put_contents(basename($imagesURL), file_get_contents($imagesURL));
}

代码如下

< ?php

//note 设置PHP超时时间

set_time_limit(0);

//note 取得样式文件内容

$styleFileContent = file_get_contents('images/style.css');

//note 匹配出需要下载的URL地址

preg_match_all("/url((.*))/", $styleFileContent, $imagesURLArray);

//note 循环需要下载的地址，逐个下载

$imagesURLArray = array_unique($imagesURLArray[1]);

foreach($imagesURLArray as $imagesURL) {

file_put_contents(basename($imagesURL), file_get_contents($imagesURL));

}

extends to During the peeling process, it is essential to download the pictures in the style file. When encountering a relatively large style file, in which there may be hundreds of images that need to be downloaded, it is most appropriate to use the following small code.

The code is as follows

Copy code

< ?php //note Set PHP timeout set_time_limit(0); //note Get the content of the style file $styleFileContent = file_get_contents('images/style.css'); //note Match the URL address that needs to be downloaded preg_match_all("/url((.*))/", $styleFileContent, $imagesURLArray); //note Loop through the addresses that need to be downloaded and download them one by one $imagesURLArray = array_unique($imagesURLArray[1]); foreach($imagesURLArray as $imagesURL) { file_put_contents(basename($imagesURL), file_get_contents($imagesURL)); }

Finally, I wish you all the best in the peeling process
