Bug #18481: Upgrade from 4.0.6 to 4.2.2 Breaks sort() and/or opendir()
From: van@armor-e.net
Operating system: Linux 2.2.20 on Alpha
PHP version: 4.2.1
PHP Bug Type: Directory function related
Bug description: Upgrade from 4.0.6 to 4.2.2 Breaks sort() and/or opendir()
The script below lists files in the current directory, which are mrtg html
and image output files. The directory listing is parsed for the host name
and a row for each host is rendered with traffic, cpu, and uptime html and
image files on the corresponding row.
Prior to upgrading from 4.0.6 to 4.2.2 the following script produced
correct output. After upgrading, multiple rows for each host are output
in no specific order. Here's the broken application:
http://tempe.dedserius.com/mrtg/
I took the application to an i386 server configured identically and tested
it and it worked fine:
http://winslow.dedserius.com/mrtg/
