oik_yourehavingmeon() – Log missing files

Description

Log missing files

In my symlinked environment in Windows I often get reports that a file does not exist when it pretty certainly does, albeit a symlinked file. This code, which used to be in the oik_boot shared library attempts to report what's wrong. But it created serious problems for REST APIs which only expect to see JSON responses. I changed it to check for WP_DEBUG before echoing anything. Then I realised that I needed better information for problem determination so I chose to log the output to the PHP error log using the error_log() function. The 'you're having me on' function is now a builtin callback function that may eventually be deprecated once the problem determination is complete. In most cases, where oik_require() has been invoked correctly we do expect the file to exist. The second test checks that the file really doesn't exist.

Usage

$string = oik_yourehavingmeon( $file );

Parameters

$file

( string ) required – the fully qualified file name

Returns

string some additional information that may help debugging.
