php and nested json: how can i access this element? -

-

here's json text:

{ "data": {     "current_condition": [{         "cloudcover": "75",         "humidity": "63",         "observation_time": "03:41 pm",         "precipmm": "0.0",         "pressure": "1020",         "temp_c": "15",         "temp_f": "59",         "visibility": "16",         "weathercode": "116",         "weatherdesc": [{             "value": "partly cloudy"         }],         "weathericonurl": [{             "value": "http:\/\/cdn.worldweatheronline.net\/images\/wsymbols01_png_64\/wsymbol_0002_sunny_intervals.png"         }],         "winddir16point": "sse",         "winddirdegree": "160",         "windspeedkmph": "7",         "windspeedmiles": "4"     }],     "request": [{         "query": "northville, united states of america",         "type": "city"     }],     "weather": [{         "date": "2013-09-24",         "precipmm": "0.0",         "tempmaxc": "20",         "tempmaxf": "67",         "tempminc": "8",         "tempminf": "47",         "weathercode": "113",         "weatherdesc": [{             "value": "sunny"         }],         "weathericonurl": [{             "value": "http:\/\/cdn.worldweatheronline.net\/images\/wsymbols01_png_64\/wsymbol_0001_sunny.png"         }],         "winddir16point": "ese",         "winddirdegree": "111",         "winddirection": "ese",         "windspeedkmph": "10",         "windspeedmiles": "6"     }] }

}

i'm trying echo 'temp_f' , not working. can't figure out i'm doing wrong. far:

$url = file_get_contents("http://blahblahblahblah"); $arr = json_decode($url,true);

and that's fails. i've done var_dump's know data there. every 'echo' attempt i've tried results in 'array' being displayed screen. i've tried many variations of following:

echo $arr->{'data'}->{'current_condition[0]'}->{'temp_f'};

can tell me i'm doing wrong? thanks!

json_decode() true second parameter gives associative array. you're trying access object.

try following:

echo $arr['data']['current_condition'][0]['temp_f'];

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
