Where can I find error log files?

Question

Where can I find error log files? I need to check them for solving an internal server error shown after installing suPHP.

Answer 1

For unix cli users:

Most probably the error_log ini entry isn't set. To verify:

php -i | grep error_log
// error_log => no value => no value

You can either set it in your php.ini cli file, or just simply quickly pipe all STDERR yourself to a file:

./myprog 2> myerror.log

Then quickly:

tail -f myerror.log
