PHP未写入错误日志

Question

File structure setup like so,

mainDirectory
-app
--logs
---errors.log
-file.php

Inside of file.php I have,

ini_set("log_errors", 1);
ini_set("error_log", "logs/errors.log");

I then try to output results like this later,

error_log( print_r($response, TRUE) );

However it just dumps to console. I then tried various checks like

if( file_exists( "logs/errors.log" ) ) {
    echo 'yup';
}
else {
    echo 'nope';
}

And each time is "nope"

Am I missing something obvious here?

Thank you.

My guess is that you're running into a permissions problem. I'm running Apache on OSX Sierra and my log files are stored in /var/log. If I try to the line below, I get a permission denied error.

file_put_contents('/var/log/apache2/errors2.log', 'Hello world');

You might consider choosing a location for your error_log that you are certain Apache has permission to write to like /tmp .

ini_set("error_log", "/tmp/errors.log");

Try using file_put_contents to test the permissions of the directory before using ini_set which can be a bit terse.
