Re: [PHP] Re: getimagesize() MySQL Image Storage (Running functions on contents of variables)
So you're saying there's no way to do what I want to do. Anybody got any other ideas? It seems so stupid to be unable to run functions that accept files on variables, with so many people using databases and whatnot these days. -Galen On Dec 7, 2003, at 1:46 AM, Justin Patrin wrote: Galen wrote: I'm using a MySQL database to store images as BLOBs.

Can anyone reproduce this problem?
I am involved in running a large forum, and ever since our upgrade to PHP
4.3.1, there have been fairly random issues with getimagesize(). It
happens only on certain images it seems. However, it wasn't happening
with 4.2. When using the following code:
?
$retval=getimagesize('http://armanii.c.crosslink.net/arcticsilver/dtmsig4
.j pg');
echo $retval[0] $retval[1] $retval[3] \n\n\n;
?
I get echo'd back. It does go an fetch the image according to a tcpdump,
but something fails after that. That is an example of one of the images
that is failing.
I am running PHP 4.3.1 w/ Apache 1.3.27 on FreeBSD 4.7. Is there
something I'm missing? Is this a bug as I think it is?
Thanks in advance!

[PHP] Re: getimagesize() with ftp-url?
Well, it is remote in the case of http-url's. Try this code: ?php $size = getimagesize(http://www.php.net/gifs/php_logo.gif;); echo 'pre'; print_r($size); echo '/pre'; ? And you will see this result: Array ( [0] = 120 [1] = 64 [2] = 1 [3] = width=120 height=64 [bits] = 8 [channels] = 3 [mime] = image/gif ) My point is that it would be nice if the same could be done with an ftp-url. I don't know if there are any issues that would make this hard to implement, but if it is possible i think this should be added to complement the http-url support. /OnionMan [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... getimagesize isn't remote. -- Nicos - CHAILLAN Nicolas [EMAIL PROTECTED] www.WorldAKT.com - Hébergement de sites Internet Stefan Wessman [EMAIL PROTECTED] a écrit dans le message de news: [EMAIL PROTECTED] Hi!

Hi, There is no way to get the filesize of a file using a remote file. You should download it to a tmp directory then check. If it is get with an http server, you should code something with sockets to ask to the http server the filesize using a request. -- Merci de nous avoir choisi. - Thanks you for your choice.

[PHP] Re: GetImageSize
Here is the function, but there is nothing wrong with the function I don't
think.
Here is the function:
function GetURLImageSize($urlpic) {
return GetImageSize($urlpic);
}
Here is how we call it:
GetURLImageSize
(http://www.domainname.com/admin/showimg.php?s=17type=categoryimage=70;);
We did write the function like that for a reason... before PHP 4.0.x we used
GetURLImageSize because GetImageSize didn't exist yet. blah blah blah... you
know what I mean.

do not load.
Example of the code perhaps? I've never had a problem with that function.
