Hello everyone, i am working on a php script and found out that the glob function is not working properly on the apache2 sapi, is working just fine on the cli version, i try with php 5.2.3, 5.2.5 y 5.2.6RC5. also try the cli version with the www-data user (the one is running the apache) and it get the same result, any one can give me a hint about this problem.
