Tip: error_log and arrays
Output buffering can be used to capture different types of output. For example, lets say your script needs to log an array, we could achieve this like:
PHP Code:
ob_start();
print_r($szArray);
$szLog = ob_get_clean();
error_log($szLog);
What this essentially does is output the array, but becuase we have output buffering on we can catch the output and store it in a varialbe ($szLog) which we can then log to a file (or other source) via the error_log function.
Hope this tip helps someone, it can be very useful for cron type scripts.
