/*
 * loadSimpleFileToArray
 *
 * what the function does
 *
 * @param (String) path to the source file
 * @return (Array)
 */
function loadSimpleFileToArray($fileName)
{
        if (!file_exists($fileName))
        {
             return array();  
        }
        $f = fopen($fileName,'r');
	$records = [];
	while(!feof($f))
		$records[] = fgets($f);
	return $records
}
