I'm not sure what you are asking about, Beau.

In the ajax-dashboard.php it has

Code: Select all

    if(file_exists("get-USNO-sunmoon.php")) { 
      include_once("get-USNO-sunmoon.php");
	  $USNOdata = getUSNOsunmoon();
   }
   if(isset($USNOdata['sunrise']))                 {$sunrise =     $USNOdata['sunrise']; }  
   if(isset($USNOdata['sunrisedate']))             {$sunrisedate = $USNOdata['sunrisedate']; }  
   if(isset($USNOdata['sunset']))                  {$sunset =      $USNOdata['sunset']; }  
   if(isset($USNOdata['sunsetdate']))              {$sunsetdate =  $USNOdata['sunsetdate']; }  
   if(isset($USNOdata['moonrise']))                {$moonrise =    $USNOdata['moonrise']; }  
   if(isset($USNOdata['moonrisedate']))            {$moonrisedate= $USNOdata['moonrisedate']; }  
   if(isset($USNOdata['moonset']))                 {$moonset =     $USNOdata['moonset']; }  
   if(isset($USNOdata['moonsetdate']))             {$moonsetdate = $USNOdata['moonsetdate']; }  
   if(isset($USNOdata['moonphase']))               {$moonphasename = $USNOdata['moonphase']; }  
   if(isset($USNOdata['illumination']))            {$moonphase = $USNOdata['illumination']; }  
   if(isset($USNOdata['hoursofpossibledaylight'])) {$hoursofpossibledaylight = $USNOdata['hoursofpossibledaylight'];}

which shows how the get-USNO-sunmoon.php is called and data returned is assigned to $variables corresponding to the Weather-Display tag names used throughout the dashboard.

$moonphase will contain the percentage illumination (0 at new moon, 100 at full moon)
$moonphasename will contain the text of the current moon phase name

Puzzled,
Ken

Hi Ken,
My Question Was my [ill] => 1 but when I printed $moonphase i get 2
but it should have been 1

I think you just didn't see in the code that there are two methods for doing the moon calcs .. one built-in (with approximations and not quite exact for data) and the second method using get-USNO-sunmoon.php which overrides the approximate calculations if available.

The get-USNO-sunmoon.php results are exact for the latitude/longitude and are the preferred displays .. that's why they override the built-in approximations.

Since you have get-USNO-sunmoon.php available and functional, it is the latter results that are shown and used in the page.

Ken,
use the example for above were [ill] => 1 if i wanted to display that what wood I print in php?
thanks Beau

I am not understanding why you would want to display the approximated value (from [ill]) instead of the accurate value (from the USNO), but I suppose you have your reasons.

To display it, you just have go look at the code in ajax-dashboard where these are done

Code: Select all

	$mooninfo = cGetMoonInfo();  /* Note:  getMoonInfo() is located in common.php */
/* returns $mooninfo of:
    [age] => 9 days, 11 hours, 57 minutes
    [ill] => 65
    [pic] => 8
    [phase] => Waxing Gibbous
    [NM] => 1294131882
    [NMGMT] => Tue, 04-Jan-2011 09:04 GMT
    [NMWD] => 09:04 GMT 04 January 2011
    [Q1] => 1294831983
    [Q1GMT] => Wed, 12-Jan-2011 11:33 GMT
    [Q1WD] => 11:33 GMT 12 January 2011
    [FM] => 1295472210
    [FMGMT] => Wed, 19-Jan-2011 21:23 GMT
    [FMWD] => 21:23 GMT 19 January 2011
    [Q3] => 1298590089
    [Q3GMT] => Thu, 24-Feb-2011 23:28 GMT
    [Q3WD] => 23:28 GMT 24 February 2011
    [Q4] => 1296700310
    [Q4GMT] => Thu, 03-Feb-2011 02:31 GMT
    [Q4WD] => 02:31 GMT 03 February 2011
    [FM2] => 1298018189
    [FM2GMT] => Fri, 18-Feb-2011 08:36 GMT
    [FM2WD] => 08:36 GMT 18 February 2011
*/
	print "<!-- cGetMoonInfo returns\n".print_r($mooninfo,true)." -->\n";
	if(!isset($moonphase)) {$moonphase = $mooninfo->ill.'%'; }

So if you really want to just print the [ill] return, then

Code: Select all

<?php print $mooninfo->ill; ?>

would do that directly.

Ken,
this code from the dashboard
can you enplane why If you print $moonphase wha the output wood not be the value of $mooninfo->ill

Code: Select all

if(!isset($moonphase)) {$moonphase = $mooninfo->ill.'%'; }

Thanks Beau

Simple... PHP executes code in a sequential order starting at the top of the page and proceeding downward, statement by statement until all the code is executed. If an assignment to $moonphase is done further down the page, then that is the value used.

Here's an excerpt from ajax-dashboard.php where it shows this for $moonphase

if($SITE['WXsoftware'] == 'WD') {
// Sample from WD: $moonage = "Moon age: 10 days,10 hours,41 minutes,80%"; // current age of the moon (days since new moon)
// Sample from WD: $moonphase = "80%"; // Moon phase %
$moonagedays = preg_replace('|^Moon age:\s+(\d+)\s.*$|is',"\$1",$moonage);
if($moonphase == '') { // MAC version of WD is missing this value
preg_match_all('|(\d+)|is',$moonage,$matches);
$moonphase = $matches[1][3];
if(isset($matches[1][4])) {
$moonphase .= '.' . $matches[1][4]; // pick up decimal;
$moonphase = round($moonphase,0);
}
$moonphase .= '%';
}
} else { // perform non-WD moon stuff
$mooninfo = cGetMoonInfo(); /* Note: getMoonInfo() is located in common.php */
/* returns $mooninfo of:
[age] => 9 days, 11 hours, 57 minutes
[ill] => 65
[pic] => 8
[phase] => Waxing Gibbous
[NM] => 1294131882
[NMGMT] => Tue, 04-Jan-2011 09:04 GMT
[NMWD] => 09:04 GMT 04 January 2011

*/
print "\n";
if(!isset($moonphase)) {$moonphase = $mooninfo->ill.'%'; }
if(!isset($newmoon)) {$newmoon = $mooninfo->NMWD; }
if(!isset($nextnewmoon)) {$nextnewmoon = $mooninfo->Q4WD; } /*check this! */
if(!isset($firstquarter)) {$firstquarter = $mooninfo->Q1WD; }
if(!isset($lastquarter)) {$lastquarter = $mooninfo->Q3WD; }
if(!isset($fullmoon)) {$fullmoon = $mooninfo->FMWD; }
if(!isset($moonphasename)) {$moonphasename = $mooninfo->phase;}
if(!isset($moonagedays)) {$moonagedays = $mooninfo->pic; }
if(!isset($moonage)) {$moonage = 'Moon age: '.$mooninfo->age.','.$mooninfo->ill.'%'; }
if(file_exists("get-USNO-sunmoon.php")) {
include_once("get-USNO-sunmoon.php");
$USNOdata = getUSNOsunmoon();
}
if(isset($USNOdata['sunrise'])) {$sunrise = $USNOdata['sunrise']; }
if(isset($USNOdata['sunrisedate'])) {$sunrisedate = $USNOdata['sunrisedate']; }
if(isset($USNOdata['sunset'])) {$sunset = $USNOdata['sunset']; }
if(isset($USNOdata['sunsetdate'])) {$sunsetdate = $USNOdata['sunsetdate']; }
if(isset($USNOdata['moonrise'])) {$moonrise = $USNOdata['moonrise']; }
if(isset($USNOdata['moonrisedate'])) {$moonrisedate= $USNOdata['moonrisedate']; }
if(isset($USNOdata['moonset'])) {$moonset = $USNOdata['moonset']; }
if(isset($USNOdata['moonsetdate'])) {$moonsetdate = $USNOdata['moonsetdate']; }
if(isset($USNOdata['moonphase'])) {$moonphasename = $USNOdata['moonphase']; }
if(isset($USNOdata['illumination'])) {$moonphase = $USNOdata['illumination']; }
if(isset($USNOdata['hoursofpossibledaylight'])) {$hoursofpossibledaylight = $USNOdata['hoursofpossibledaylight'];}
}

Follow the logic:
1) if the weather software is Weather-Display, the native tag $moonage is parsed to extract $moonphase, otherwise
2) the built-in function cGetMoonInfo() returns an approximation of the illumination in $mooninfo->ill and that becomes $moonphase

if get-USNO-sunmoon.php is installed and successfully returns data, then the $USNOdata['illumination'] becomes $moonphase

It's always best to read the code to understand how something works.
