Greetings,
I have a php web app I 'inherited' and am working on tweaking/cleaning. Below is from a common function script, called common.php. The only include or require is shown below.
The scenario:
When I execute a script to generate some graphics, I receive the following error:
PHP Fatal error: Cannot redeclare get_client_ip() (previously declared in /home/dshield/php/common.php:14) in /home/dshield/php/common.php on line 13
The common.php file is included in a required file, db_report.php, from the graphics gen script.
I have grepped and searched through all included/required files, and can find no signs of a problem. The inclusion of common.php in db_report.php is not in a loop structure. It seems to be localized to the common.php module. If I run any other script that either directly or indirectly calls common.php, I receive an error.
The entire function is included.
Thanks for any help,
monger
