get image according to date function.

[mp04]

Hey,

I have a script that was custom made for me that, grabs a image from another site (my own other site) the script is:

 

 
<?


    $filename="URL To other site";
    $indirectory="Directory where the image is";
    $destinationpath="Path to where it should save it.";



    $contents = file_get_contents($filename);
    $url=dirname($filename);
    $keywords=0;
    $keywords1=0;

    $keywords = strpos($contents,"src");
    while ($keywords>0)
    {
        $filename=retbetween1($contents,"src=\"","\"",$keywords1);

        if (substr($filename,-4)==".jpg")
        {
            if (strpos($filename,$indirectory)>0)
            {
                echo "Writing file ";
                if (substr($filename,0,7)=="http://")
                {
                    $bname=basename($filename);
                    $contents1 = file_get_contents($filename);
                    echo $filename." to ";
                    file_put_contents($destinationpath,$contents1);
                    echo "$destinationpath. Success";
                }
                else
                {
                    $bname=basename($filename);
                    $contents1 = file_get_contents($url."/".$filename);
                    echo $url."/".$filename." to ";
                    file_put_contents($destinationpath,$contents1);
                    echo "$destinationpath. Success";
                }
            }
        }
    }


function retbetween($mainstring,$search,$search1,$cnt)
{
    global $sttable;
    global $keywords;
    global $keywords1;

    $keywords = strpos($mainstring,$search,$cnt);

    $keywords1 = strpos($mainstring,$search1,$keywords+strlen($search));
    $sl=strlen($search);
    $s2=strlen($search1);
    $strw=substr($mainstring,$keywords,($keywords1+$s2)-($keywords));
    $sttable=$keywords1+$s2;
    return $strw;

}
function retbetween1($mainstring,$search,$search1,$cnt)
{
    global $sttable;
    global $keywords;
    global $keywords1;
    $keywords = strpos($mainstring,$search,$cnt);
    if ($keywords>0)
    {
        $keywords1 = strpos($mainstring,$search1,$keywords+strlen($search));
        $sl=strlen($search);
        $s2=strlen($search1);
        $strw=substr($mainstring,$keywords+strlen($search),($keywords1)-($keywords+strlen($search)));
        $sttable=$keywords1+$s2;
        return $strw;
    }
    else
        return "";

}

?>
</form>
</body>
</html>

 

 

 

Now this has worked perfectly so far, since site would only show one image a day, and server would go there, and pick up that one image from that one folder.

 

Now, We have made some changes to the daily image feature on the web, where the user can go back a few days or months etc, BUT on the site it self it shows 5 pictures from the last five days now. SO now the server is confused as far as which ONE image it should grab. causeing the script to now stall.

 

So basically what we did I talked with the admin to the page and he said what he can do is name each image with a date, so today image would be: 08-07-09.jpg.

 

what I want to do, is maybe a addition to that script above so it can get the date from the server, and match it with the image and THEN transfer it.

 

any ideas? Please remember I am a newbie to PHP and still learning, so please keep that in mind.

 

Thanks.

You can get the filename of the image by exploding on the period (or you can so a substr since the date in the filename is a fixed length) and compare the first chunk against today's date, which would be date("m-d-Y") in your case. If they match then display. www.php.net is a good resource, look up "explode" and "date".
