php3.ini:
magic_quotes_gpc        =       Off    
track_vars                      =       On           
upload_max_filesize = 260000000 ; max of 260mb files

DEC UNIX 4.0C?

Basically what is happening is, I call is_dir, after having run chmod, and when I look at the perms on the file I chmod'ed, the privs have been changed immediately after calling is_dir

this script doesn't actually show this behavior (I can't isolate it out of my large script), but if you notice the output, it appears to be wrong...

bug.php3 --

#!/homea/file/bin/php
<?php
$dir = "/homea/jan";
$webdir = $dir . "/public_html";
$file = $dir . "/myfile";
 
echo fileperms($file) . "\n";
chmod($file, 0700);
echo fileperms($file) . "\n";
if(!is_dir($webdir)) {
   mkdir($webdir);
}
echo "just did is_dir conditional.\n";   
echo fileperms($file) . "\n";
chmod($file, 0700);
echo fileperms($file) . "\n";        

output --
