im trying to do this json decoding my professor suggested i try, but i cant seem to pass the address part. Any ideas?
{"fname": "Nick", "mname": "F.", "lname": "Delos Reyes", "birthday": "1995-04-01", "address": { "Country": "America", "state": "New York" }}
Expected output:
Name : Nick F. Delos Reyes
Birthday : 1995-04-01
Address :Caramoran, New York
There are many ways to it. Following is an example to parse the name.
$array = json_decode('{"fname": "Nick", "mname": "F.", "lname": "Delos Reyes", "birthday": "1995-04-01", "address": { "Country": "America", "state": "New York" }}', true);
$name = [$array['fname'], $array['mname'], $array['lname']];
$outputName = 'Name:' . implode(' ', $name);
It uses json_decode() to convert the JSON to an associative array. It then put the name parts in an array. It uses implode() to join the name parts into a string.
For example. I want to get coordinates of all node buildings in bbox.
PHP
$queryBuildings="[out:json];node['building']({$y1},{$x1},{$y2},{$x2});out;";
$data = file_get_contents("http://overpass-api.de/api/interpreter?data={$queryBuildings}")
One element from result:
{
"type": "node",
"id": 29537155,
"lat": 54.6744568,
"lon": -2.1421066,
"tags": {
"building": "house",
"description": "Abandoned (2007). Associate with lead mine workings above it?",
"name": "Flushiemere House"
}
}
I want to get only lon and lat fields it's possible?
You can use skeleton print mode (out skel) which omits all tags, thus being slightly shorter. So your request should become: [out:json];node['building']({$y1},{$x1},{$y2},{$x2});out skel;
Currently csv output mode ([out:csv]) is the only mode where you can select the fields to be shown.
<?php
$data = '{
"type": "node",
"id": 29537155,
"lat": 54.6744568,
"lon": -2.1421066,
"tags": {
"building": "house",
"description": "Abandoned (2007). Associate with lead mine workings above it?",
"name": "Flushiemere House"
}
}';
$test = json_decode($data);
var_dump($test->lon);
First use json_decode to parse the response body:
$parsed_data = json_decode($data);
Then you can access the various fields like so:
$lat = $parsed_data->lat;
$lon = $parsed_data->lon;
{
"name": "2Pac",
"album": "All Eyez on Me",
"track": "All Eyez on Me",
"duration": "5:08",
"trackNo": ""
},
{
"name": "2Pac",
"album": "2Pac Greatest Hits",
"track": "Keep Ya Head Up",
"duration": "4:24",
"trackNo": "1"
},
{
"name": "2Pac",
"album": "2Pac Greatest Hits",
"track": "2 Of Amerikaz Most Wanted",
"duration": "4:07",
"trackNo": "2"
},
{
"name": "50 Cent",
"album": "Get Rich Or Die Tryin%27",
"track": "P.I.M.P.",
"duration": "4:10",
"trackNo": "11"
},
{
"name": "50 Cent",
"album": "Get Rich Or Die Tryin%27",
"track": "Like My Style",
"duration": "3:13",
"trackNo": "12"
},
I have lots of json data formatted this way and was looking for a way to manipulate the data so that it only has one artist name and then the albums for that artist then songs within each album. PHP would be fine so I can convert things, Any help would be appreciated.
Use these:
json_decode
array_map, array_filter, for loops, what you like
json_encode
Basically it boils down to:
parse
mangle
format
I'll leave the exercise to you, but browsing these functions and similar questions here should get you started. If you have anything to show then, you may ask for more specific help.
I'm trying to match a form supplied UTC time and form supplied event name string with an array read in from a file. The problem is that it seems to always match even when it shouldn't. The format of the file will always be constant, so I know I'll be looking for a value within double quotes, so after failing to get results with strpos(), I tried preg_match...and now match everything. Code and example output follow ($utc and $event_name)are already set and correct when we get here):
$match1 = "/\"{$utc}\"/";
$match2 = "/\"{$event_name}\"/";
print "Match Values: $match1, $match2<p>";
foreach($line_array as $key => $value) {
print "Value = $value<p>";
if ((preg_match($match1,$value) == 1) and (preg_match($match2,$value) == 1))
{
print "Case 1 - False<p>";
} else {
print "Contains targets: $value<p>";
//code to act on hit will go here
}
}
And here's what comes back:
Match Values: /"1371033000000"/, /"Another test - MkII "/
Value = { "date": "1357999200000", "type": "meeting", "title": "Plant and Animal Genome Conference, San Diego, CA", "description": "NCGAS to present at Plant and Animal Genome Conference, San Diego, CA", "url": "http://www.event1.com/" }
Contains targets: { "date": "1357999200000", "type": "meeting", "title": "Plant and Animal Genome Conference, San Diego, CA", "description": "NCGAS to present at Plant and Animal Genome Conference, San Diego, CA", "url": "http://www.event1.com/" }
Value = { "date": "1357693200000", "type": "meeting", "title": "Testing Addition", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
Contains targets: { "date": "1357693200000", "type": "meeting", "title": "Testing Addition", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
Value = { "date": "1371033000000", "type": "meeting", "title": "Another test - MkII", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
Contains targets: { "date": "1371033000000", "type": "meeting", "title": "Another test - MkII", "description": "This is a fake event.", "url": "http://pti.iu.edu" }
I should only be matching the last one, but they all match. I've been playing with the regex and can't seem to find the right magic.
Simplified it and got what I was after:
foreach($line_array as $key => $value) {
print "Value = $value<p>";
if (preg_match("/$utc/",$value) and preg_match("/$event_time/",$value))
{
print "Contains targets: $value<p>";
} else {
print "Case 1 - False<p>";
//code to act on hit will go here
}
}
But answer 2 got me in the right direction. Thanks, Ian!
You don't need to do anything weird inside a double-quoted string, just drop your variable in as is...
$match1 = "/$utc/";
$match2 = "/$event_name/";
I suspect your regexes are looking for zero-length strings.
Also, this line doesn't need so many parentheses...
if (preg_match($match1,$value) == 1 and preg_match($match2,$value) == 1) {
[...]
}

Then, I have a foreach statement which adds the data to a MYSQL database:
foreach($result as $key => $value) {
if($value) {
mysql_query("INSERT INTO `games_db`.`Games` (`title`, `description`, `image`, `category`, `page`, `rating`, `width`, `height`, `tags`) VALUES ('$value->name', '$value->description', '/images/$pageid.jpg', '$category', '$pageid', '$value->rating', '$value->width', '$value->height', '$value->tags')")
}
My question is, What do I have to do to show and insert the tags from the JSON file? Currently, When I run this page, the data for the "tags" column just says "Array".
You can use json_decode() as so:
$jsonString = '[{"key_mappings": "", "screen2_thumb": "http://games.mochiads.com/c/g/siegius-arena/screen2_thumb.png", "video_url": "http://www.youtube.com/watch?v=S7MDxObgJxw", "rating": "Teen", "screen1_thumb": "http://games.mochiads.com/c/g/siegius-arena/screen1_thumb.png", "metascore": 43.63, "height": 500, "screen3_thumb": "http://games.mochiads.com/c/g/siegius-arena/screen3_thumb.jpg", "stage3d": false, "screen3_url": "http://games.mochiads.com/c/g/siegius-arena/screen3.jpg", "recommendation": 5, "coins_revshare_enabled": null, "category": "Fighting", "screen4_thumb": "http://games.mochiads.com/c/g/siegius-arena/screen4_thumb.png", "uuid": "6789c7e3-fd27-345e-85d9-e6a58165ae57", "author": "Juice-Tin", "thumbnail_large_url": "http://games.mochiads.com/c/g/siegius-arena/_thumb_200x200.png", "author_link": "https://www.mochimedia.com/community/profile/Juice-Tin", "controls": [["C", "Item"], ["V", "Spell"], ["X", "Heavy Attack"], ["Z", "Fast Attack"], ["fire", "na"], ["jump", "na"], ["movement", "arrow"]], "languages": ["en"], "swf_url": "http://games.mochiads.com/c/g/siegius-arena/Siegius%20Arena_.swf", "recommended": true, "game_tag": "e0e05c5c5fd1a61b", "achievements_enabled": false, "zip_url": "http://games.mochiads.com/c/g/siegius-arena.zip", "screen1_url": "http://games.mochiads.com/c/g/siegius-arena/screen1.png", "updated": "2012-10-25T15:47:01.953336-08:00", "description": "Fight in arena battles and upgrade your gladiator in this Action-RPG about betrayal and revenge.", "tags": ["siegius", "arena", "gladiator", "rome", "battle", "fight", "upgrade", "rpg", "fans", "en"], "swf_file_size": 10142842, "leaderboard_enabled": false, "game_url": "http://www.mochimedia.com/games/siegius-arena", "screen2_url": "http://games.mochiads.com/c/g/siegius-arena/screen2.png", "slug": "siegius-arena", "categories": ["Action", "Fighting"], "instructions": "", "name": "Siegius Arena", "created": "2012-10-25T12:47:55.080005-08:00", "control_scheme": "{\"C\": \"Item\", \"fire\": \"na\", \"jump\": \"na\", \"V\": \"Spell\", \"X\": \"Heavy Attack\", \"Z\": \"Fast Attack\", \"movement\": \"arrow\"}", "popularity": 0, "feed_approval_created": "2012-10-25T13:30:53.505710-08:00", "coins_enabled": null, "thumbnail_url": "http://games.mochiads.com/c/g/siegius-arena/_thumb_100x100.png", "screen4_url": "http://games.mochiads.com/c/g/siegius-arena/screen4.png", "alternate_url": "", "resolution": "800x500", "width": 800}]';
$jsonObject = json_decode($jsonString);
foreach ($jsonObject->tags as $tag) {
echo $tag . PHP_EOL;
//Do something
}
If you use less than PHP 5.2.0, you can use the JSON PECL Extension
I should also add that you shouldn't use the mysql functions any more - they're deprecated. See: Why shouldn't I use mysql_* functions in PHP?
use json_decode():
json_decode — Decodes a JSON string
$jsonObject = json_decode($string); // returns an object
or:
$jsonArray = json_decode($string, true); // if second argument is true, returned object will be converted to an associative array
Edit:
as suggested by #nickhar: NOTE: You need PHP 5.2.0 or above to use json_decode()
Or one of the emulations floating around – #mario
