Limit amount of 000000 for microtime

[jjmusicpro]

is there a way to limit the 000000 or the percision on microtime()? right now it will say 1.254112111 is there a way i can make it display only say 1.253?

 

foreach($URLarray as $K => $URL)
{
$mtime = microtime(); 
$mtime = explode(' ', $mtime); 
$mtime = $mtime[1] + $mtime[0]; 
$starttime = $mtime; 
if( url_exists($URL) )
{
	$data = file_get_contents($URL);
	unset($data);//dump	the data
	$mtime = microtime(); 
	$mtime = explode(" ", $mtime); 
	$mtime = $mtime[1] + $mtime[0]; 
	$endtime = $mtime; 
	$totaltime = ($endtime - $starttime); 
	$UrlResults[$URL] = array("Access" => true, "Time"=>$totaltime); 
	echo "			<script language='javascript'>display('$K', '$totaltime seconds');</script>"; 
}else{
	$UrlResults[$URL] = array("Access" => false); 
	echo "			<script language='javascript'>display('$K', 'Failed');</script>"; 
}
ob_flush();
flush();
}

I know my snippet code isn't using microtime.  But the concept is there.  All you need to use is the function number_format();

 

<?php
$number = 3.14159265;
$formattedNumber = number_format($number, 2);

echo "Number: ".$number;
echo "<br/>";
echo "Formatted: ".$formattedNumber;
?>

or you can use round

 

<?php
$number = 3.14159265;
$formattedNumber = round($number, 2);

echo "Number: ".$number;
echo "<br/>";
echo "Formatted: ".$formattedNumber;
?>
