Use PHP implementation to download images from CSS files _php instances

As a veteran and professional Mr Skinner staff, I have accumulated a wealth of Mr Skinner experience since I began to invest in the great Internet from third day. I believe that every programmer who does the web will have a similar experience.

In the Mr Skinner process, it is essential to download the picture in the style file. When you encounter a larger style file, which may have hundreds of images to download, it is most appropriate to use this little code.

< php/* more & Original php framwork Copyright (c) 2007-2008 ismole Inc author:kimi Documentation: Download the pictures in the style file, Water Special Mr Skinner tool *///note set PHP timeout set_time_limit (0)//note get style file content $stylefilecontent = file_get_contents (' Images/style.css //note matches the URL address that needs to be downloaded Preg_match_all ("/url\ ((. *) \)/", $styleFileContent, $imagesURLArray);//note loop needs to download the address, download $ Imagesurlarray = Array_unique ($imagesURLArray [1]); foreach ($imagesURLArray as $imagesURL) {file_put_contents ( BaseName ($imagesURL), file_get_contents ($imagesURL));}

And then we'll share a package of good classes.

/** * Get image address in CSS and save to local */class getincssimage{/** * Picture saved * @param $cssUrl CSS URL address * @param $dir the directory where the picture is saved * @return void* /static Public Function SaveImage ($CSSURL, $dir) {$content = file_get_contents ($CSSURL); $patterns = '/images (. *). jpg|gif|png)/'; The regular change Preg_match_all ($patterns, $content, $matches) according to the different addresses; $imagesUrls = $matches [0];if (!is_dir ($dir)) mkdir ( DirName (__file__). '/'. $dir, 0777), foreach ($imagesUrls as $image) {Ob_start (); $imageUrl = "http://www.xx.com/". $image;//This address was originally obtained using a program. Lazy ReadFile ($IMAGEURL); $img = Ob_get_contents (); Ob_end_clean (); $size = strlen ($img); $localImage = $dir. STRCHR ($ Image, '/'); Save to local image address $fp = fopen ($localImage, ' a '); Fwrite ($fp, $img); fclose ($FP);} }}} $content = Getincssimage::saveimage ('/css/css.css ', ' image ');

Finally, I wish you a Mr Skinner in the process, a grilled to the end!

In addition are attached about file_put_contents definition and usage

The file_put_contents () function writes a string to the file.
Same as calling fopen (), fwrite (), and fclose () in turn.

Grammar

File_put_contents (File,data,mode,context)
