Hi everyone,  let me first preface this by saying that I know very little about php and json.  What I know is that I need a webpage that can provide specific weather data for a group of coxswains using their cellphones while out on patrol.  Don't worry that you might be talking down to me, because I promise that you won't be when it comes to my codeing skills.  That said, I created an API key for weather underground.  This provides me with a json file like this:

I wrote a php script like this to parse the data that I need and display it:

<!DOCTYPE html>
<html>
<body>
<?php 
$json_string = file_get_contents("http://api.wunderground.com/api/<key removed for this post>/conditions/tide/q/PA/Marcus_hook.json"); 
$parsed_json = json_decode($json_string); 
$wlocation = $parsed_json->{'current_observation'}->{'display_location'}->{'full'}; 
$temp_f = $parsed_json->{'current_observation'}->{'temp_f'}; 
$humid = $parsed_json->{'current_observation'}->{'relative_humidity'};
$wind = $parsed_json->{'current_observation'}->{'wind_string'};
$pressure = $parsed_json->{'current_observation'}->{'pressure_mb'};
$pressuretrend = $parsed_json->{'current_observation'}->{'pressure_trend'};
$feels = $parsed_json->{'current_observation'}->{'feelslike_string'};
$wtime = $parsed_json->{'current_observation'}->{'observation_time_rfc822'};

$tlocation = $parsed_json->{'tide'}->{'tideinfo'}->{'tidesite'};

/* $temp_f = $parsed_json->{'current_observation'}->{'temp_f'}; 
$humid = $parsed_json->{'current_observation'}->{'relative_humidity'};
$wind = $parsed_json->{'current_observation'}->{'wind_string'};
$pressure = $parsed_json->{'current_observation'}->{'pressure_mb'};
$pressuretrend = $parsed_json->{'current_observation'}->{'pressure_trend'};
$feels = $parsed_json->{'current_observation'}->{'feelslike_string'};
$wtime = $parsed_json->{'current_observation'}->{'observation_time_rfc822'};*/


echo "Current temperature in ${wlocation} is: ${temp_f} F, but it feels like ${feels}<BR>"; 
echo "The current humidity is ${humid}<BR>";

echo "The winds are ${wind}<BR>";

if ($pressuretrend == "+") {
    echo "The current pressure is ${pressure} and rising <BR>";
} else {
    echo "The current pressure is ${pressure} and falling <BR>";
}
echo "This weather report last updated ${wtime} <BR>";
echo "<Hr>";
echo "<BR>";
?>


</body>
</html>

Which prints out a nice report like this:

 

Current temperature in Marcus Hook, PA is: 41.9 F, but it feels like 42 F (6 C)
The current humidity is 68%
The winds are From the South at 2.0 MPH Gusting to 2.0 MPH
The current pressure is 1014 and falling
This weather report last updated Fri, 17 Jan 2014 13:57:08 -0500

 

 

 

What I can't figure out, as in completely and hopelessly lost, is how in the world to get it to make a table of the tides.  The json file, for example, uses "pretty" over and over again.  I need it to find EACH instance of "pretty" and add it to the tide chart, not just one.

 

I hope I'm clear on what I'm trying to do.  If not, please ask questions, just keep in mind that I'm a coding infant!

First a comment: please don't use the ->{} syntax when it's not necessary. It's valid, yes, but not really something that should be used often, and definitely not when there's a "normal" version that works.

$wlocation = $parsed_json->current_observation->display_location->full;
It's a bit hard to tell from that JSON (it's formatted oddly) but I think the array you want to loop over is tide->tide_summary.

foreach ($parsed_json->tide->tide_summary as $summary) {
	print_r($summary);
}
To get a table... it depends how you want it to be outputted. What should the resultant HTML look like? Maybe with some sample data?

Requinix,

Thank you for your help.  I apologize that my syntax is goofy.  I'm reading php books and adapting examples from the book and internet to do what I need.  I'm completely open to suggestions on how to do the code simpler/cleaner.  I just personally don't have the skills for it.  This is just one of those situations were "while I suck at it, everyone else I know sucks worse, but it needs to be done" if you know what I mean!

 

The whole point of this page is a clean simple text display of mission critical data that can be pulled up and displayed quickly on a mobile phone using 3g.  For the tide data I'm simply looking for table that displays

date         time               type       height

1/17/14    6:18am          high        +4.72 feet

1/17/14    12:15pm        slack       +1.2 feet

1/17/14    5:45 pm         low          -3.5 feet

 

just very simple and low bandwidth.

 

Thanks again for any help/suggestions.

try something like

$data = json_decode($str, true);

echo "<pre><p>{$data['tide']['tideInfo'][0]['tideSite']}</p>";

$units = $data['tide']['tideInfo'][0]['units'];
foreach ($data['tide']['tideSummary'] as $tidedata){
    echo $tidedata['date']['pretty'] . ' ' ;
    if ($tidedata['data']['height']) {
        echo floatval($tidedata['data']['height']) . " $units ";
    }
    echo $tidedata['data']['type'] . '<br/>'  ;
}
echo '</pre>;

Another option:

$json = json_decode($f);



$zone = new DateTimeZone($json->tide->tideInfo[0]->tzname);
$unit = $json->tide->tideInfo[0]->units;
echo ("<table>\n");
echo ("<tr><th>Date/Time</th><th>Height</th><th>Type</th></tr>\n");

// Iterate through each tide->tideSummary object in the array
foreach($json->tide->tideSummary as $tide) {
   // Create the DateTime object
   $dt = DateTime::createFromFormat('U', $tide->utcdate->epoch);
   // Must specifically set TZ, else UTC is used
   $dt->setTimeZone($zone);

   // Echo out the table row
   echo("<tr>\n");

   // Format the DateTime as desired
   // See http://us1.php.net/manual/en/datetime.format.php
   echo("<td>{$dt->format('Y-m-d H:i:s e')}</td>\n");

   // Use printf to extract just the numeric part of the height,
   // then add the unit (which is the full spelling, rather than
   // the abbreviation provided within the height element).
   // This is a fault of the API; if it is going to provide the
   // unit as it is, it should now be adding that to it (or it
   // should be providing a raw numeric value)
   if (!empty($tide->data->height)) {
      printf("<td>%0.2f %s</td>\n", $tide->data->height, $unit);
   } else {
      // Just print an empty cell
      echo("<td> </td>\n");
   }

   echo("<td>{$tide->data->type}</td>\n");
   echo("</tr>\n");
}

echo("</table>\n");

Thank you everyone for all the help!  I've been working all night long.  With your help the page is starting to look like something!  I'm sure you guys could have done my 7-8 hours of work in 1o minutes or so, but from just having picked up the books and starting on the script last week I'm kind of proud of  myself.  I was even able to modify the examples above to parse to forecast data that I had previously given up on.

 

Thank you again.  If you're curious your help can be seen at http://patrolinfo.com/test/index3.php
