PHP regular match the remote image address in the article and download the image to the local_PHP tutorial

Today I am doing a simple collection program that requires downloading the content of the other party's website, and then saving the pictures in the content on the local server. Now I will introduce to you my specific operation method. Downloading pictures mainly uses the file_get_contents function. The specific method as follows.

Here we use PHP regular expressions to achieve:

The code is as follows

代码如下	复制代码
$content = '这里是文章内容，这里插入一张图片测试 '; $content = stripslashes ( $content ); $img_array = array (); // 匹配所有远程图片 preg_match_all ( "/(src|SRC)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|bmp|png))/isU", $content, $img_array ); // 匹配出来的不重复图片 $img_array = array_unique ( $img_array [2] ); print_r($img_array);

Copy code

$content = 'Here is the content of the article, insert a picture here to test';

$content = stripslashes ( $content );

$img_array = array ();

// Match all remotes Picture

preg_match_all ( "/(src|SRC)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|bmp|png))/isU", $content, $img_array );

// Matched unique images

$img_array = array_unique ( $img_array [2] );

代码如下

复制代码

//保存文章中远程图片到本地 //作者：yanue; // 文件保存目录路径(请更换为你自己的路径， 你可以echo一下) $save_path = $_SERVER ['DOCUMENT_ROOT'] . 'swfupload/attached/'; // 文件保存目录URL $save_url = '/swfupload/attached/'; $save_path = realpath ( $save_path ) . '/'; // 图片存储目录 $imgPath = $save_path . date ( "Ymd" ); $imgUrl = $save_url . date ( "Ymd" ); // 创建文件夹 if (! is_dir ( $imgPath )) {  @mkdir ( $imgPath, 0777 ); } $content = '这里是文章内容，这里插入一张图片测试 '; $content = stripslashes ( $content ); $img_array = array (); // 匹配所有远程图片 preg_match_all ( "/(src|SRC)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|bmp|png))/isU", $content, $img_array ); // 匹配出来的不重复图片 $img_array = array_unique ( $img_array [2] ); print_r($img_array); // 时间无限制 set_time_limit ( 0 ); foreach ( $img_array as $key => $value ) {  $value = trim ( $value );  // 读取远程图片  $get_file = @file_get_contents ( $value );  // 保存到本地图片名称  $imgname = date ( "YmdHis" ) . '_' . rand ( 10000, 99999 ) . "." . substr ( $value, - 3, 3 );  // 保存到本地的实际文件地址（包含路径和名称）  $fileName = $imgPath . '/' . $imgname;  // 实际访问的地址  $fileurl = $imgUrl . "/" . $imgname;  // 文件写入  if ($get_file) {   $fp = @fopen ( $fileName, "w" );   @fwrite ( $fp, $get_file );   @fclose ( $fp );  }  // 替换原来的图片地址  $content = ereg_replace ( $value, $fileurl, $content ); } echo $content; ?>

print_r($img_array);

The remote image is matched above, we need to keep it locally. Two points need to be noted here: 1. Image saving path (image storage directory) 2. Actual access to the image address The following is a complete example: (You can save it to the local server and modify the corresponding place for testing)

The code is as follows

Copy code

//Save the remote image in the article to local location//Author: yanue; // File saving directory path (please change it to your own path, you can echo it)$save_path = $_SERVER ['DOCUMENT_ROOT'] . 'swfupload/attached/';// File Save directory URL$save_url = '/swfupload/attached/';$save_path = realpath ( $save_path ) . '/';// Image storage directory$imgPath = $save_path . date ( "Ymd" );$imgUrl = $save_url . date ( "Ymd" );// Create folderif (! is_dir ( $imgPath )) { @mkdir ( $imgPath, 0777 );}$content = 'Here is the article content, insert a picture here to test $> $Content = Stripslashes ($ Content); (); > // match all remote pictures preg_match_all ( "/(src|SRC)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|bmp|png))/isU", $content, $img_array );// Matched unique images$img_array = array_unique ( $img_array [2] );print_r($img_array);// Unlimited timeset_time_limit ( 0 );foreach ( $img_array as $key => $value ) { $value = trim ( $value ); // Read remote image $get_file = @file_get_contents ( $value ); // Save to local image name $imgname = date ( "YmdHis" ) . '_' . rand ( 10000, 99999 ) . "." . substr ( $value, - 3, 3); // Actual file address saved to local (including path and name) $fileName = $imgPath . '/' . $imgname; // Actual accessed address $ fileurl = $imgUrl . "/" . $imgname; // File writing if ($get_file) { $fp = @fopen ( $fileName, "w" ); @ fwrite ( $fp, $get_file ); @fclose ( $fp ); } // Replace the original image address $content = ereg_replace ( $value, $fileurl, $content ) ;}echo $content;?> http://www.bkjia.com/PHPjc/444581.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/444581.htmlTechArticleToday I am doing a simple collection program that requires downloading the content of the other party’s website and then saving the images in the content locally.
