I have been trying to get php to put its errors into a separate log file: "php_log". In php.ini I set:
error_log = /var/log/httpd/php_log
The php errors continue to show up in httpd's "error_log". I've reset apache many times since I changed the setting (I've tried other file names as well), and phpinfo() confirms all settings are the way I want them.
Here are some other settings you may or may not find relevant:
error_reporting = E_ALL
display_errors = Off # On on the test server (same results of coarse)
log_errors = On
log_errors_max_len = 1024
ignore_repeated_source = Off
report_memleaks = On
track_errors = Off
Thanks for the help!
