An inefficient workaround is to set realpath_cache_size=0 in your php.ini, That fixes the issue, but you take a performance hit in terms of extra lstat calls. Still working on a simple fix that doesn't break everything for this one. ------------------------------------------------------------------------ [2012-01-28 18:48:31] rasmus@php.net Never mind, I see it now. % php phptest/phpinc OK But % php /phptest/phpinc Warning: include(/phptest/phpfile): failed to open stream: No such file or directory in /phpinc on line 2 Warning: include(): Failed opening '/phptest/phpfile' for inclusion (include_path='.:/usr/local/lib/php') in /phpinc on line 2 ------------------------------------------------------------------------ [2012-01-28 18:44:05] rasmus@php.net I am unable to reproduce this with current PHP versions. Here is what I did: % cd / % ln -s / phptest % echo "OK" > /phpfile % echo '<?php include "/phptest/phpfile";' > /phpinc % /home/rasmus/php-src/branches/PHP_5_4/sapi/cli/php phpinc OK % /home/rasmus/php-src/branches/PHP_5_3/sapi/cli/php phpinc OK % php phpinc OK % cd /phptest % php phpinc OK What am I missing? This seems to be exactly the setup that thekid described. ------------------------------------------------------------------------ [2012-01-28 13:39:24] grobmeier at gmail dot com I can only agree with startup09. Please fix it. Thousands 1&1 (among others) customers are using old PHP because of this one. It is going to have birthday soon. I cannot upgrade my Open Source projects because 5.2 ist sill used on so many hosts. You need to get this done if you really have an interest your users migrate to 5.3. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
