Make WP_DEBUG_LOG to match a path

[juliobox]

Hello,

i propose to make the possibility for WP_DEBUG_LOG to be a path to a log file like ERRORLOGFILE already is.

False = no log,
True = actuel default path wp-content/debug.log
/home/logs/wp.log = this file!

The patch includes 2 files, code and docs.

Thank you

This sounds like a good idea, but needs a bit more accurate logic. Looks like null, 0 or 1 would be treated as a path now.

Something like this might work:

if ( WP_DEBUG_LOG ) {
	ini_set( 'log_errors', 1 );
	if ( is_string( WP_DEBUG_LOG ) ) {
		ini_set( 'error_log', WP_DEBUG_LOG );
	} else {
		ini_set( 'error_log', WP_CONTENT_DIR . '/debug.log' );
	}
}
