PHP图像缓存

Question

I am having a problem with php image caching . I have already posted this on the authors issue page, however it isn't active.

Web server: NGINX

PHP Version: 5.5.9-1ubuntu4.14

I am getting this error Final image URL is broken . The page looks like this There should be 100 images displayed but it dies at the third. The page should look something similar to this (this is the localhost design)

It is returning this URL

There should be a / between the mediapage.zips.me and core , however it is a local image so I don't see why it should even need the host name.

How I am doing this is,

On the top of each page I am calling another page which contains the setup of the class

<?php
    //Calls the php-image things
    include 'test.php';

?>

Inside test.php

<?php 
    require_once 'core/classes/ImageCache.php';
    $imagecache = new ImageCache();
?>

Image page

<?php 
    //Directory NON-CACHED images are stored in
    $dir    =   "i/";

    //Array of files in the Directory
    $files1 =   scandir($dir);
    //Used to limit results (100's of images)
    $count = 0;
    foreach ($files1 as $key) {
        //If the file name is longer than 3 chars and the count is less 
        //than the amount of images I want displayed.
        if (strlen($key) > 3 && $count <= 100){
            $count++;
            //dir2 is the directory/nameofFile.extension
            //Eg: i/testImage.png
            $dir2   =   $dir.''.$key;
            $info = new SplFileInfo($key);
            //Image Cache variable
            $cached_src = $imagecache->cache($dir2);
?>
    <tr>
        <td>
            <!-- Link for light box for full resolution image -->
            <a href="<?php echo $dir2;?>" data-popup="lightbox">
                <!-- src of cached image is outputted and the alt is the name of the uncached image. -->
                <img src="<?php echo $cached_src;?>" alt="<?php echo $key;?>" class="img-rounded img-preview">
            </a>
        </td>
        <!-- More table stuff... -->
    </tr>

<?php
        } //End If
    } //End for
?>

I have tried adding a / to the directory name $dir but it says that it cant find the directory when I do that.

Answer 1

        <!-- Link for light box for full resolution image -->
        <a href="<?php echo $dir2; ?>" data-popup="lightbox">
            <!-- src of cached image is outputted and the alt is the name of the uncached image. -->
            <img src="/<?php echo $cached_src; ?>" alt="<?php echo $key; ?>" class="img-rounded img-preview">
        </a>

This should work by simpling prepending a slash before the $cached_src .

I would take a look at ImageCache github page for reference. If the cached image doesn't exist yet, the script will use $_SERVER['HTTP_HOST'] . So verify what is in that. It looks like if your $_SERVER['HTTP_HOST'] doesn't end with a slash, then your url won't have one.
