How to access php error log from url?

Soylolo

For convenience, i'm used to read/empty error log from an url in my browser

domain.com/wp-content/custom/read-error-log.php
`$logfile = dirname( DIR, 3 ) . '/logs/error.log';
$log = file_get_contents( $logfile );

echo '<h1>PHP 8.2 Error Log</h1>';
echo '<pre>';
print_r( $log );
echo '</pre>';`

But since log file is in /var/www/nginx/ i can't access and get this error:

"PHP message: PHP Warning: file_get_contents(): open_basedir restriction in effect. File(/var/www/domain.com/logs/error.log) is not within the allowed path(s): (/var/www/:/usr/share/php/:/tmp/:/var/run/nginx-cache/:/dev/urandom:/dev/shm:/var/lib/php/sessions/) in /var/www/domain.com/htdocs/wp-content/custom/ver-errorlog.php on line 13;"

Is there a way to access error.log like this without compromising security by messing with open_basedir

You could maybe try creating a symlink to the log file in a permitted path (i.e. inside /var/www/yourdomain.com/)

I've tried with symlink but error still persist:

"PHP Warning: file_exists(): open_basedir restriction in effect. File(/var/www/domain.com/htdocs/wp-content/simlinked.log) is not within the allowed path(s): (/var/www/:/usr/share/php/:/tmp/:/var/run/nginx-cache/:/dev/urandom:/dev/shm:/var/lib/php/sessions/) in /var/www/domain.com/htdocs/wp-content/custom/varias/ver-errorlog.php on line 5"

I wondered why i couldn't open the symlink already in /var/www/domain.com/logs/error.log, since "/var/www/:" is in allowed path

I guess open_basedir is smart enough to point to the actual file, right?

Ah yeah, that would make sense.
Adding the log path to open_basedir is probably the easiest then.

Or you could maybe do something with an alias, along the lines of:

location /view-log {
    alias /var/www/yourdomain.com/logs/error.log;
    allow YOUR.IP.ADDR.HERE;
    deny all;
    default_type text/plain;
}

That worked as a charm. Thank you!
