 * 
 * PHP SERVER PERFORMANCE MEASURING.
 * STRING, ARRAY, OUTPUT (BUFFERED) AND MATH OPERATION BASED MEASURING.
 * ONLY INTERNAL PERFORMANCE IS EVALUATED, DOES NOT MEASURE DISK OR
 * NETWORK PERFORMANCE, RETURNS ONLY SERVER LOAD DEPENDENT SAMPLES, 
 * SO PLEASE AVERAGE YOUR SERVERS RUNTIME(S) FOR COMPARISION.
 * 
 * USAGE:
 * 
 * STANDARD ITERATION OF ALL OPERATIONS IS 10.000 (TEN THOUSAND). 
 * YOU CAN START THE SCRIPT WITH A CUSTOM, LOWER ITERATION AMOUNT IF NECESSARY.
 * 
 * FOR EXAMPLE IF YOUR PHP EXECUTION TIME LIMIT IS TO LOW AND YOUR SERVER 
 * IS NOT ABLE TO PROCESS THIS PERFORMANCE METERING SCRIPT IN THAT TIME. (OLD SERVERS)
 * IN THAT CASE WHEN THE SCRIPT RETURNS NOTHING, CURRUPT DATA, ONLY A NUMBER, OR AN ERROR 
 * YOU MUST REDUCE THE ITERATIONS.
 * 
 * e.g. RUN:  .../php_perfmon.php?iterations=5000
 * 
 * WHEN MANUALLY REDUCING THE ITERATIONS THE SCRIPT -AUTOMATICALLY- DETECTS THAT 
 * AND EXTRAPOLATES YOUR RUNTIME TO GIVE YOU A COMPARABLE RESULT! 
 * 
 * IMPORTANT: DECREASE ITERATIONS AS LITTLE AS POSSIBLE!
 * 
 * PLEASE FEEL FREE TO SEND SERVER(s) PERFORMANCE RESULTS EVALUATED TO:
 * 
 * php_perfmon@mindcatch.com 
 * 
 * I WILL ADD THEM TO THE PUBLIC COMPARISON DATA FILE FOR THE COMMUNITY. THANKS!
