is_dir and is_file() work on one server but not another

[ravenslay3r@gmail.com]

I'm using a script to grab images from a directory and put them to the
screen, but i want it to ignore sub-directories like CVS/ . Adding the
tag "&& !is_dir($file)" to the correct conditional statement solved it
on my test server, but not on the actual site.

How is this possible? How can I fix it?


thanks,

RavenSlay3r



Working open-test site on Dreamhost.com servers (PHP 5.0 now i think)

http://guardiansrealm.net/lcpaver/index.php?colors_classic&paving_stones&paver_colors

Broken Mainsite running on BlueGravity.com servers (PHP 4 & 5)
http://lcpaver.com/index.php?colors_...s&paver_colors



Here's the script:
<?php
$image_dir = "images/colors/classic";
$dir_ptr = opendir("$image _dir/");




# grab images and put in an array
while ($file = readdir($dir_pt r)) {
$content[] = $file;
}
closedir($dir_p tr);
sort($content);




# output list of files found to page source for testing purpose
echo ("<!-- Files in " . $image_dir . " :\n");
foreach ($content as $file) {
echo ($file . "\n");
}
echo ("-->\n");




# Create new array with images only
$cnt=0;
foreach ($content as $image) {
if ( $image != "." && $image != ".." &&
!is_dir($image) ) {
# gets size of $image
$img_info = getimagesize("$ image_dir/$image");
// $img_info = $img_info[3];
$img_info = "style=\"width: 120px;
height:80px;\"" ;
$img_name = str_replace ("_", " ", $image);
$img_name = str_replace (".jpg", "",
$img_name);
# display $image
echo ("<div class=\"onecolo r\">");
echo ("<div class=\"imgshad ow\"
style=\"float: left;\">\n");
echo ("<img src=\"$image_di r/$image\"
alt=\"$img_name \"
$img_info>\n");
echo ("</div>\n");
echo ("<p>$img_na me</p>");
echo ("</div>\n");
$cnt++;
}
}
$maxItems = $cnt-1;


# output number of files found to page source for testing
purpose echo ("<!-- " . $maxItems . " images found -->\n");


if ($maxItems = 0) {
echo ("<h1>There are no images in this library</h1>");
}
?>

Re: is_dir and is_file() work on one server but not another

Hi Raven
I just got an email from dreamhost support (I only sent it about twenty
minutes ago - great support) They didn't
actually upgrade to php 5, they upgraded to 4.3.10, the email announcment
they sent was misleading I believe. I thought they were upgrading to php5
too.

php5 from your actual site might break scripts, this does not happen on
dreamhost as php4 is still there.

My initial impression is to check the following bits:

>$image_dir = "images/colors/classic";
>$dir_ptr = opendir("$image _dir/");[/color]

OK, you're opening up a given directory, relative to the current directory.
Current working directory may not be the same between the two?

Aren't you missing "$image_dir/" as a prefix for the is_dir() call? You've
correctly got it in the getimagesize() call below.

Re: is_dir and is_file() work on one server but not another

Very intresting but good to know about Dreamhost. That means MY
web-site will still work! I was afraid to look... :-P Do you use them
also? They have been great to me!

I wouldn't expect PHP5 to be breaking on is_dir() but i'm not ruling
out the possiblilty yet.

Re: is_dir and is_file() work on one server but not another

Goodpoint. Alot of this was existing code I inherited from another
web-designer and i'm just adding to/maintaining it... <sigh>

I thought the fullpathname was included in $image, but perhaps not.
I'll give this a try!

Thanks,
Raven

Re: is_dir and is_file() work on one server but not another

Hi Yes
I use them aswell , they are great in everyway particullarly support.
However I have been told that they are overselling and thus sites with them
are slow. My site never seemed slow to me, although I have seen faster.

I'm actually only new to php, but have heard that as well as functions which
wont work in version 4 because they from 5, it is also true of the reverse.

The guy from dreamhost said that it will be a while until 5 is instailled,
he said they'd probabely wait until it is packaged with debian (which makes
sense) as it would break nearly everyone's scripts.
