oik_batch_cd_drill_down() – Drill down to locate the lowest file

You appear to be a bot. Output may be restricted

Description

Drill down to locate the lowest file

In Windows, when you're using symlinks and PHP's chdir() the resulting directory reported by getcwd() reflects the real directory. This might not be the one you first thought of. It makes finding files a little tricky, hence the need for this function.

Usage

$string|null = oik_batch_cd_drill_down( $path, $locate_file );

Parameters

$path

( string ) required – the ending directory

$locate_file

( string ) optional default: wp-config.php – the file we're looking for

Returns

string|null the lowest directory or null
