Php: external caching script

[iMaarten]

Hello, i'm looking for a script that caches data (mostly images) from an external site to my own server. Example: MYSITE/cache.php?=image.png: cache.php gets image.png from an external site and saves it to the server and sent the local copy the next time image.png is requested

Wha tis the platform? is it VB?

My own platform, it doesn't need to be integraded in the site.

you may run a script on specific db tables to make the following:

1. get data from database
2. seeks for img tags (regex)
3. downloads the image file
4. replaces the original image url in the article
5. saves the new article

The problem is they are dynamic images made by a script

i assume you always have to download only from one site, see the code below

    $url = 'site.com/cache.php?=image.png';
    $url = parse_url($url,PHP_URL_QUERY);
    $imgFile = preg_replace("/^=/","",$url);
    // set your images folder path here
    $imagesPath =  " images/".$imgFile;

    if(!file_exists(($imagesPath))) {
        
        // i assume you always have to download from only one website
        // i.e http://thatsite.com/image.png
        
        $otherSiteUrl  = 'http://thatsite.com/' .  $imgFile;
        if(!file_put_contents($imagesPath, file_get_contents($otherSiteUrl))){
            echo 'Failed to download file';
            $imagesPath = null;
        }
    }
    echo $imagesPath; 

edit: if you wants to display the image itself instead of echo location to it, replace echo $imagesPath with below code

if(!empty($imagesPath)) {
        $fileParts  = pathinfo($imagesPath);
        $fileExtenstion = $fileParts['extension'];
        switch( $fileExtenstion ) {
        case "gif":
            $type="image/gif";
        break;
        case "png":
            $type="image/png";
        break;
        case "jpg":
            $type="image/jpg";
        break;
        default:
            $type="image/jpg";
        }
        header("Content-Type: $type");
        readfile($imagesPath);
    }
