If you are like me you've got a command line script that has to process through thousands of things and you like know how far along it is and how much longer it is going to take. Today I crated this general function to help me monitor the status of where I am with my process and I though making some type of timer would be cool too. Have fun with it.

So to use this function you just need to pass it

$i: Current number you are processing (in my case an array so 0 really is 1
$c: Total number of items to do
$m: any type of message or item number that is being processed
$noTiming: which turns off the timing functionality if you really don't care to see how long or how much furter you have to go.

list($usec, $sec) = explode(' ', microtime());
$script_start = (float) $sec + (float) $usec;

function outputStatus( $i, $c, $m, $noTiming = false )
{
	global $script_start;
	/**	Current Number	**/
	$i++;
	$i = str_pad( $i, strlen($c), ' ', STR_PAD_LEFT );
	
	/**	Percent Done	**/
	$p = str_pad( number_format( round( $i/$c*100, 2 ), 2 ), 5, ' ', STR_PAD_LEFT );
	
	/**	Show Timing Status	**/
	if( !$noTiming )
	{
		/**	Elapsed Time	**/
		list($usec, $sec) = explode(' ', microtime());
		$script_end = (float) $sec + (float) $usec;
		$elapsed_time = round( $script_end - $script_start, 0);
		$elapsed_min = floor( $elapsed_time/60 );
		$elapsed_sec = str_pad( $elapsed_time - ( $elapsed_min * 60 ), 2, '0', STR_PAD_LEFT );
		
		/**	Time Left	**/
		$left_time = $elapsed_time / $i * $c - $elapsed_time;
		$left_min = floor( $left_time/60 );
		$left_sec = str_pad( round( $left_time - ( $left_min * 60 ),0), 2, '0', STR_PAD_LEFT );
		$left_min = str_pad( $left_min, 2, ' ', STR_PAD_LEFT );
		$timing = "Time: ($elapsed_min:$elapsed_sec) - Left: ($left_min:$left_sec) ";
	}
	print "$i of $c ($p%) $timing'$m'\n";
	
}
