以天，小时，分钟和秒显示刻度

Question

I'm trying to show an UpTime in Days, Hours, Minutes, Seconds. Something like 20 days, 4 hours, 9 minutes, 3 seconds

Here is my PHP Code:

// Get uptime with my SNMP class
$iTicks = $oHardwareMonitoring->fGetSystemUpTime();

// Convert Ticks to seconds
$iSecondes = $iTicks / 100;

// Convert seconds to Days, Hours, Minutes, Seconds
$sSecondes = gmdate('s', $iSecondes);
$sMinutes  = ($sSecondes > 60 ? round(($sSecondes / 60), 0) : null);
$sHeures   = ($sMinutes > 60 ? round(($sMinutes / 60), 0) : null);
$sJours    = ($sHeures > 24 ? round(($sHeures / 24), 0) : null);

// Show the result
echo '<b>'.$sInfosUptime.'</b> : '.
($sJours != null ? $sJours.' '.DAY.' ' : null).
($sHeures != null ? $sHeures.' '.HOUR.' ' : null).
($sMinutes != null ? $sMinutes.' '.MINUTE.' ' : null).
$sSecondes.' '.SECONDE;

When I execute the PHP, I get 38 Seconde(s) for 429859 ticks.

How to show the uptime correctly?

Answer 1

$sSecondes can never be greater than 60 because you use gmdate('s', $iSecondes); which returns a value between 00 and 59. Therefore the conditions that follow will never be evaluated as true.

Using the following line:

$sMinutes = ($iSecondes > 60 ? round(($iSecondes / 60), 0) : null);

returns:

1 HOUR 72 MINUTE 38 SECONDE

Better but not exactly what is expected.

We can get the proper amount of each unit by using modulo, division and floor():

$sSecondes = $iSecondes%60;
$sMinutes  = floor($iSecondes%3600/60);
$sHeures   = floor($iSecondes%86400/3600);
$sJours    = floor($iSecondes/86400);

Which returns:

1 HOUR 11 MINUTE 38 SECONDE
