mkozlow Posted February 27, 2012 Share Posted February 27, 2012 So im trying to use a script to fetch the weather forecast from weatherunderground and im using their weather API functionality. Basically im trying to get the output to be something like (Continuing down in a list) (Day of week): (Current conditions) (High temp)-(Low temp) this is what I have: #!/usr/bin/php <?php $json_string = file_get_contents("http://api.wunderground.com/api/MY_APIKEY/forecast/q/19104.json"); $parsed_json = json_decode($json_string); $day = $parsed_json->{'forecast'}->{'simpleforecast'}->{'forecastday'}->{'date'}->{'weekday_short'}; $high = $parsed_json->{'forecast'}->{'simpleforecast'}->{'forecastday'}->{'high'}->{'fahrenheit'}; $low = $parsed_json->{'forecast'}->{'simpleforecast'}->{'forecastday'}->{'low'}->{'fahrenheit'}; $conditions = $parsed_json->{'forecast'}->{'simpleforecast'}->{'forecastday'}->{'conditions'}; echo "Forecast:\n"; echo "${day}: ${conditions} ${high}-${low}\n"; ?> the output of the get_file_contents is: "response": { "version": "0.1", "termsofService": "http://www.wunderground.com/weather/api/d/terms.html", "features": { "forecast": 1 } }, "forecast": { "txt_forecast": {}, "simpleforecast": { "forecastday": [ { "date": { "epoch": "1330398000", "pretty": "10:00 PM EST on February 27, 2012", "day": 27, "month": 2, "year": 2012, "yday": 57, "hour": 22, "min": "00", "sec": 0, "isdst": "0", "monthname": "February", "weekday_short": "Mon", "weekday": "Monday", "ampm": "PM", "tz_short": "EST", "tz_long": "America/New_York" }, "period": 1, "high": { "fahrenheit": "59", "celsius": "15" }, "low": { "fahrenheit": "36", "celsius": "2" }, "conditions": "Partly Cloudy", "icon": "partlycloudy", "icon_url": "http://icons-ak.wxug.com/i/c/k/partlycloudy.gif", "skyicon": "mostlysunny", "pop": 0, "qpf_allday": { "in": 0, "mm": 0 }, "qpf_day": { "in": 0, "mm": 0 }, "qpf_night": { "in": 0, "mm": 0 }, "snow_allday": { "in": 0, "cm": 0 }, "snow_day": { "in": 0, "cm": 0 }, "snow_night": { "in": 0, "cm": 0 }, "maxwind": { "mph": 9, "kph": 14, "dir": "South", "degrees": 180 }, "avewind": { "mph": 6, "kph": 10, "dir": "South", "degrees": 171 }, "avehumidity": 65, "maxhumidity": 78, "minhumidity": 48 }, { "date": { "epoch": "1330484400", "pretty": "10:00 PM EST on February 28, 2012", "day": 28, "month": 2, "year": 2012, "yday": 58, "hour": 22, "min": "00", "sec": 0, "isdst": "0", "monthname": "February", "weekday_short": "Tue", "weekday": "Tuesday", "ampm": "PM", "tz_short": "EST", "tz_long": "America/New_York" }, "period": 2, "high": { "fahrenheit": "50", "celsius": "10" }, "low": { "fahrenheit": "37", "celsius": "3" }, "conditions": "Clear", "icon": "clear", "icon_url": "http://icons-ak.wxug.com/i/c/k/clear.gif", "skyicon": "mostlysunny", "pop": 0, "qpf_allday": { "in": 0, "mm": 0 }, "qpf_day": { "in": 0, "mm": 0 }, "qpf_night": { "in": 0, "mm": 0 }, "snow_allday": { "in": 0, "cm": 0 }, "snow_day": { "in": 0, "cm": 0 }, "snow_night": { "in": 0, "cm": 0 }, "maxwind": { "mph": 8, "kph": 13, "dir": "NW", "degrees": 318 }, "avewind": { "mph": 5, "kph": 8, "dir": "ESE", "degrees": 123 }, "avehumidity": 53, "maxhumidity": 69, "minhumidity": 39 }, { "date": { "epoch": "1330570800", "pretty": "10:00 PM EST on February 29, 2012", "day": 29, "month": 2, "year": 2012, "yday": 59, "hour": 22, "min": "00", "sec": 0, "isdst": "0", "monthname": "February", "weekday_short": "Wed", "weekday": "Wednesday", "ampm": "PM", "tz_short": "EST", "tz_long": "America/New_York" }, "period": 3, "high": { "fahrenheit": "43", "celsius": "6" }, "low": { "fahrenheit": "41", "celsius": "5" }, "conditions": "Rain", "icon": "rain", "icon_url": "http://icons-ak.wxug.com/i/c/k/rain.gif", "skyicon": "cloudy", "pop": 80, "qpf_allday": { "in": 0.71, "mm": 18 }, "qpf_day": { "in": 0.5, "mm": 12.7 }, "qpf_night": { "in": 0.21, "mm": 5.3 }, "snow_allday": { "in": 0, "cm": 0 }, "snow_day": { "in": 0, "cm": 0 }, "snow_night": { "in": 0, "cm": 0 }, "maxwind": { "mph": 16, "kph": 26, "dir": "ESE", "degrees": 106 }, "avewind": { "mph": 9, "kph": 14, "dir": "ESE", "degrees": 115 }, "avehumidity": 91, "maxhumidity": 95, "minhumidity": 64 }, { "date": { "epoch": "1330657200", "pretty": "10:00 PM EST on March 01, 2012", "day": 1, "month": 3, "year": 2012, "yday": 60, "hour": 22, "min": "00", "sec": 0, "isdst": "0", "monthname": "March", "weekday_short": "Thu", "weekday": "Thursday", "ampm": "PM", "tz_short": "EST", "tz_long": "America/New_York" }, "period": 4, "high": { "fahrenheit": "54", "celsius": "12" }, "low": { "fahrenheit": "32", "celsius": "0" }, "conditions": "Overcast", "icon": "cloudy", "icon_url": "http://icons-ak.wxug.com/i/c/k/cloudy.gif", "skyicon": "cloudy", "pop": 0, "qpf_allday": { "in": 0, "mm": 0 }, "qpf_day": { "in": 0, "mm": 0 }, "qpf_night": { "in": 0, "mm": 0 }, "snow_allday": { "in": 0, "cm": 0 }, "snow_day": { "in": 0, "cm": 0 }, "snow_night": { "in": 0, "cm": 0 }, "maxwind": { "mph": 10, "kph": 16, "dir": "WSW", "degrees": 253 }, "avewind": { "mph": 4, "kph": 6, "dir": "West", "degrees": 280 }, "avehumidity": 95, "maxhumidity": 100, "minhumidity": 87 } ] } } } I feel like i need to define different variables for each day like dayx, highx, lowx, conditionsx, etc where x=period and it increases the period every time you run through. I remember learning this in my intro to java class but in all honesty i forgot, even if i did know if i was on the right path. Any help? I'd appreciate it.

requinix Posted February 27, 2012 Share Posted February 27, 2012 forecastday is actually an array of objects. You can (and should) foreach over it.

mkozlow Posted February 27, 2012 Author Share Posted February 27, 2012 forecastday is actually an array of objects. You can (and should) foreach over it. ok so like i said im a beginner and really dont know wtf im doing. would i incorporate a foreach while parsing the output? or instead of? would it be appropriate to do something like this (i feel like im missing some syntax (meaning brackets and ; and stuff if you notice shout out please. i should probably be using a script editor instead of notepad but meh): foreach (forecastday as &$key) { if ($key = $date) { foreach (date as &$d) { if $d = $weekday_short { $day = $d;} else{} }} else if ($key = $high) { foreach (high as &$h) { if $h = $fahrenheit { $hi = $h;} else{} }} else if ($key = $low) { foreach (low as &$l) { if $l = $fahrenheit { $lo = $l;} else{} }} else if ($key = $conditions) { $cond = $key;} } Link to comment https://forums.phpfreaks.com/topic/257888-beginner-needing-help-with-json-script/#findComment-1321849 Share on other sites More sharing options...
mkozlow Posted February 28, 2012 Author Share Posted February 28, 2012 am i like really far off, or is it just not worth the time to figure out? just looking for a point in the right direction i dont mind doing my own research to learn. I just need a starting point Link to comment https://forums.phpfreaks.com/topic/257888-beginner-needing-help-with-json-script/#findComment-1321967 Share on other sites More sharing options...
codebyren Posted February 28, 2012 Share Posted February 28, 2012 You're heading in the right direction but are traversing the data incorrectly. <?php $json = file_get_contents('weather.json'); $json = json_decode($json); // You can learn a lot about how PHP interpreted the data by un-commenting these lines: // print_r($json); // exit; // Now it's just a case of following the nested structure to the "forecastday" array. // (which is an array of objects as requinix mentioned) foreach ($json->forecast->simpleforecast->forecastday as $day) { echo "{$day->date->weekday}: {$day->conditions} <br>"; echo "{$day->low->fahrenheit} - {$day->high->fahrenheit} °F <br>"; echo '<br>'; } exit; ?> Hope that helps clear it up.
