I'm having difficulty extracting JSON values (obtained by using a URL) into email variables. The following code works (I have removed identifiable and usable data).
$addr = "https://98905:Twmdf56sn0cb#geoip.maxmind.com/geoip/v2.1/insights/".$ipaddr;
// fetching geoip data in JSON format
$json = (file_get_contents($addr));
//parsing JSON format to object format
$obj = json_decode($json);
// assigning values to separate variables for email message
$var_country = $obj->country->names->en;
$var_city = $obj->city->names->en;
$var_city_confidence = $obj->city->confidence->en;
$var_city_geoname_id = $obj->city->geoname_id->en;
$var_location = $obj->location->accuracy_radius->en;enter code here
However one set of data is an array that looks like this (identifiable and usable data scrubbed):
"subdivisions":[{"geoname_id":5166838,"iso_code":"NY","confidence":24,"names":{"ja":"ニューヨーク州","fr":"New York","ru":"Нью-Йорк","en":"New York","zh-CN":"纽约州","de":"New York","pt-BR":"Nova Iorque","es":"Nueva York"}}]
My difficulty lies in extracting the "names" "en" part from the subdivisions multi-array. All the previous arrays are single units, this multi and I'm having difficulty drilling down to the "names" "en" part from subdivisions and getting that value into an array using the same process as above.
If you are just looking to get the en key, you can do something like this:
$objects->subdivisions[0]->names->en;
If you are wanting retrieve each set of data, loop through them like so:
foreach($objects->subdivisions[0]->names as $key => $value) {
echo $key . ' --- ' . $value . '<br />';
}
and modify to your needs.
Try with
$p=json_decode('{"subdivisions":[{"geoname_id":5166838,"iso_code":"NY","confidence":24,"names":{"ja":"ニューヨーク州","fr":"New York","ru":"Нью-Йорк","en":"New York","zh-CN":"纽约州","de":"New York","pt-BR":"Nova Iorque","es":"Nueva York"}}]}');
$enNames = array();
foreach($p->subdivisions as $subdivision){
$enNames[]=$subdivision->names->en;
}
print_r($enNames);

I am looking to make a multi line graph from this example.
Instead of using data from a CSV file I'm building an array of values from the database:
$token_prices = sw::shared()->prices->getForTokenID($token_id);
$token_prices_array = array();
foreach ($token_prices as $token_price) {
$token_prices_array[] = [
"date" => $token_price['date'],
"close" => $token_price['close']
];
}
$second_token_prices = sw::shared()->prices->getForTokenID(3);
$second_token_prices_array = array();
foreach ($second_token_prices as $second_token_price) {
$second_token_prices_array[] = [
"date" => $second_token_price['date'],
"close" => $second_token_price['close']
];
}
$all = array_merge($second_token_prices_array, $token_prices_array);
foreach ($all as $datapoint) {
$result[$datapoint['date']] []= $datapoint['close'];
}
Data output:
{"15-Jun-18":["8.4","0.14559"],"16-Jun-18":["8.36","0.147207"],"17-Jun-18":["8.42","0.13422"],"18-Jun-18":["8.71","0.146177"],"19-Jun-18":["8.62","0.138188"],"20-Jun-18":["8.45","0.128201"],
My issue is with plugging the data from the database in:
var tokendata = <?php echo json_encode($result) ?>;
data = tokendata;
data.forEach(function(d) {
d.date = parseTime(d.date);
d.close = +d.close;
d.open = +d.open;
});
I get an issue here "data.forEach is not a function"...
How can I fix this to use the data from the database?
Here is the Fiddle
It looks like you are embedding the results of the query php page as a JSON string -- if you want to iterate over that data as an array, you will have to parse it back into a Javascript object first.
I'm assuming that the first code snippet is running on a different server, and so the $result array is not directly available to your javascript code -- is this why you are trying to set a variable to the encoded return value? If so, it's not the best way to pull data into your page's script, but this may work for you:
var data = JSON.parse('<?php echo json_encode($result)?>');
or even:
var data = eval(<?php echo json_encode($result)?>);
Both methods assume that your result is returned as a valid json string, since there is no error checking or try/catch logic. I honestly don't know what the output of the json_encode() method looks like, so if you still can't get it working, please update your post with an example of the returned string.
I have input file that looks something like this:
{"name": "foo"}{"name": "bar"}
How to parse that?
If you're sure, that the individual JSONs are valid, you can try to transform it into an array of JSON objects, like this:
$data = '{"name": "foo"}{"name": "bar"}';
$data = str_replace('}{', '},{', $data);
$data = '[' . $data . ']';
// Now it's valid
// [{"name": "foo"},{"name": "bar"}]
Since }{ is always invalid in JSON, it's safe to say, that it won't affect your data.
there are several way to parse json objects such as this .. but you must know the exact structure of that object ..
one way is to iterate each child ..
foreach($jsonObj as $obj)
{
// access my name using
$obj->name;
$obj->someotherfield
// or iterate again .. assuming each object has many more attribute
foreach($obj as $key => $val)
{
//access my key using
$key
// access my value using
$val
}
}
there are tons of other ways to do that so .. and also , a valid json is like [{"name": "foo"},{"name": "bar"}]
I am trying to convert this JSON string into a PHP array. The JSON string is stored in my database and I have already retrieved it.
{
"users": "user1, user2"
}
I need to convert the above JSON string into an array like the following but dynamically.
$myArray = array("user1", "user2")
This is my code:
$row = mysqli_fetch_array($result);
$json = $row['json'];
$decode = json_decode($json);
$list = $decode->users;
$myArray = explode(',', $list);
This code doesn't work in my program but when I print the array with print_r it looks identical to if I print $myArray from the nondynamic string. This is a concern because the nondynamic string works.
The separator between the usernames is comma+space, you're just using comma when you explode, so the second and following usernames are getting a space at the beginning. Try:
$myArray = explode(', ', $list);
I recommend that you change the JSON structure so you store an actual array, rather than a comma-separated list.
{
"users": ["user1", "user2"]
}
Even better would be to change your database structure so the users are in a real table, rather than being wrapped in JSON. This would allow you to perform queries that search for users easily and efficiently.
I have some issue with a decoded Json object sended to a php file. I have tried some different format like this
{"2":"{Costo=13, ID=9, Durata_m=25, Descrizione=Servizio 9}","1":"{Costo=7, ID=8, Durata_m=20, Descrizione=Servizio 8}"}
or this.
[{"Costo":"7.5","ID":"3","Durata_m":"30","Descrizione":"Barba Rasoio"},{"Costo":"4.5","ID":"4","Durata_m":"20","Descrizione":"Barba Macchinetta"}]
In order the first, any suggestions helps me, then i have converted previous string using GSON, however php doesn't decode.
This is my php:
//Receive JSON
$JSON_Android = $_POST["JSON"];
//Decode Json
$data = json_decode($JSON_Android, true);
foreach ($data['servizi'] as $key => $value)
{ echo "Key: $key; Value: $value<br />\n";
}
How can I access single elements of array? What I'm doing wrong? Thanks in advance
I think you should check the content in this way
//Receive JSON
$JSON_Android = $_POST["JSON"];
//Decode Json
$data = json_decode($JSON_Android, true);
foreach ($data as $key => $value) {
echo "FROM PHP: " . $value;
echo "Test : " .$value['ID'];
}
your elements of {Costo=7, ID=8, Durata_m=20, Descrizione=Servizio 8}
are not properly formated as an array element. That is a pure string and not an array value.
This is a json object with 1 element of array:
{
"1": {
"Costo": 7,
"ID": 8,
"Durata_m": 20
}
}
The Inside are json objects. Therefore your json string was not properly formated to operate with that logic. What you had was an element of a string. That is the reason why it was a valid json (passing jsonlint) but was not the correct one that you wanted to use.
UPDATE
Because this format is fix, I have a non-elegant way:
//Receive JSON
$JSON_Android = $_POST["JSON"];
//Decode Json
$data = json_decode($JSON_Android, true);
foreach ($data as $key => $value) {
//to separate each element
$newArray = explode(',',$value);
$newItem = explode('=', $newArray[1]);
echo "ID". $newItem[1];
}
That would be the dirty way to do it ONLY IF THE PLACEMENT OF DATA IS FIX. (ie the second element of the first explode is always ID.
I will leave it to someone else to make the suggested code better. I would recommend more to ensure that the json you are receive is proper because as I explained, it is incorrectly formated and as an api developer, you want an adaptive way for any given client to use the data efficiently.
Confusing title, the basics are that I'm saving a fully sorted and ordered multidimensional array from a script and into MySQL. I then, on another page, pull it from the database and unserialize it, and then proceed to print it out with this,
$s = "SELECT * FROM gator_historical_data WHERE channelid = '{$chanid}'";
$r = $link->query($s);
$comboarray = array();
while ($row = mysqli_fetch_assoc($r)) {
$comboarray[] = unserialize($row['dataarray']);
}
foreach ($comboarray as $item) {
$desc = $item['content']['description'];
$title = $item['content']['title'];
$datetime = $item['datetime'];
// ... ^^^ problems getting array data
}
The problem is that it doesn't take the full array from MySQL, only the first entry and thus only prints the first 'array'. So where the returned value from dataarray looks like this (var_dump): http://pastebin.com/raw.php?i=Z0jy55sM the data stored into the unserialized $comboarray only looks like this (var_dump): http://pastebin.com/raw.php?i=Ycwwa924
TL;DR: Pulling a serialized multidimensional array from a database, unserializing and it loses all arrays after the first one.
Any ideas what to do?
The string you've got is a serialized string plus something more at the end that is also a serialized string again and again:
a:3:{s:6:"source";s:25:"World news | The Guardian";s:8:"datetime ...
... story01.htm";}}a:3:{s:6:"source";s:16:"BBC News - World";
^^^
This format is not supported by PHP unserialize, it will only unserialize the first chunk and drop everything at the end.
Instead create one array, serialize it and store that result into the database.
Alternatively you can try to recover for the moment by un-chunking the string, however in case the paste was done right, there are more issues. But on the other hand the paste obvious isn't the done fully correct.
