以编程方式查找PHP错误日志文件

Question

I know that the PHP log file is located at /var/log/nginx/error.log for my personal box, but I am interested in pragmatically finding out where the error log file is.

I have tried:

 ini_get('error_log');

But my php ini doesn't specify error_log, so it's blank. And since apache/ngnix each store different places, is there a way to find out where errors are being written to? I don't mind to use exec() to run a command to get it, but

php -i | grep error_log

Returns

error_log => no value => no value

For my set up

You need phpinfo()

unfortunately it outputs rather than returning the information you need - but on that page quite a few folk have given examples of cathing the output
