Hi,
In the root directory, "index.php" file we have two lines of code that I am curious about:

Code Select Expand

error_reporting(E_ALL);

and

Code Select Expand

$sttime = microtime(true);

What is the purpose of these two lines and how are they used?
Thanks,
Rafael

Hi, 

first http://php.net/manual/en/function.error-reporting.php

and second starts debugging, which can be enabled at the end of the file, removing the commenting around

Code Select Expand

//Debugging 
/*
if(is_admin()) {
echo "Time Elapsed: ".(microtime(true) - $sttime)."s [br /]";
echo "Database debug";
echo '';
$db->debug();
echo '';
echo '----------------';
echo "Cache database debug";
echo '';
$cachedb->debug();
echo '';
}
*/

I see...
And where/how does the

Code Select Expand

error_reporting(E_ALL);

logs/displays these errors?

Thanks

It displays them on the page as any php script (not a good idea for live sites).
