I am very new to JSON and i really need help. So I have been given this $oldAuctions object and after using PHP's json_decode function (json_decode($oldAuctions, TRUE);) it returned me something like this that has 11 objects with 9 set of name/value pairs in each...
{
"recent_results": [
{
"closing_yield": "0.800",
"auction_id": "106",
"use_buy_it": "0",
"issuer": "National Bank",
"term": "1 Year",
"is_charity": "1",
"end_date": "12-26-2012",
"closing_price": "100.000000",
"issue_type": "FDICs"
},
{
"closing_yield": "1.090",
"auction_id": "339",
"use_buy_it": "0",
"issuer": "National Bank",
"term": "1 Year",
"is_charity": "1",
"end_date": "12-12-2012",
"closing_price": "100.000000",
"issue_type": "FDICs"
},
{
"closing_yield": "2.000",
"auction_id": "041",
"use_buy_it": "0",
"issuer": "National Bank",
"term": "5 Year",
"is_charity": "1",
"end_date": "09-11-2012",
"closing_price": "100.000000",
"issue_type": "FDICs"
}
]
}
Now I need to grab each pair and save their values in an array. For example, I want to grab the auction_id and save it's values in an array.....how can I do that?
Also, just for simple testing purpose I tried to print out the values first...but that didn't work either...
foreach($oldAuctions as $IDs)
{
echo 'Ids: '.$IDs->auction_id;
}
I would really appreciate your help. Thank you!
After invoking json_encode your array $oldAuctions has become a JSON string. You can not iterate through it as array or object as its a string.
As $oldAuctions is already an array you can simply use forach
foreach($oldAuctions['recent_results'] as $result){
echo 'Ids: '.$result['auction_id']. "\n";
}

I have a json array within {} braces and which are retrieved from $response5.
$json ='[
{
"Collectioncentre_Name": "Kattupakkam - Collection Centre 001",

}
]';
$data=json_decode($json,true);
$your_string="";
foreach($data as $key=>$v){
$your_string.=$data[$key]['Collectioncentre_Name'].",".$data[$key]
['Session_ID'].",".$data[$key]['Date'].",".$data[$key]
['MilkSession'].",".$data[$key]['Farmer_ID'].",".$data[$key]

$csvdata= trim($your_string, ",");
//$csvdata = $your_string;
echo $csvdata."\r\n";
Actually these json arrays are the output from $response5. And if I put the code like $json ='[$response5;] instead of adding whole arrays, am not getting the actual result which I got when I added array values. Did I miss anything or did I need to add more code?
To put the various comments together, when trying to put the whole JSON together from the original data, instead of...
$json ='[$response5;]
to make it a valid JSON array you need to use...
$json ="[$response5]";
Then to output each row of data plus headings (using implode rather than long winded adding each field together), you can use...
$data=json_decode($json,true);
$your_string=implode(",",array_keys($data[0])).PHP_EOL;
foreach($data as $key=>$v){
$your_string.=implode(",",$v).PHP_EOL;
}
echo $your_string."\r\n";
for example, i have json result like this
[
{
"title": "x1",
"url": "domain.com"
},
{
"title": "x2",
"url": "example.com/"
},
{
"title": "x3",
"url": "site.com/cam"
},
]
The result of json will be randomly, i want to scrape ['x']['url'] path from that json, but the value of ['url'] must be "site.com/cam", and as you know, the results from json will change randomly, so I do not know which json path with value is "site.com/cam".
is there any suggestion? Thank you
Try this
$index = array_search('site.com/cam',array_column(json_decode($json),'url'));

Output
$index = 2
Oh and there is a typo in your JSON
}, <-- remove comma here.

I have a file that sends a request through curl, when I hit the url which is formatted as http://www.example.com/api/something?id=24 I get a series of arrays back in JSON form. It looks like:
24: {
pe: {
id: "24",
name: "Blah",
engine_src: "blah",
each_lender: "1",
soap_request: "0",
lenders: {
0: "3",
1: "1",
2: "6",
3: "12"
}
},
lenders: {
0: {
id: "1",
platform_id: "2",
lender_id: "3",
engine_id: "24",
status: "1",
engine_lender_id: "3",
engine_lender_name: "choice #1"
},
}
There are several other numbers and arrays in the list that look similar. I need to return the array that is associated with the id in the url and only that array.
I have set a new variable which looks like
$selected = (int)$_REQUEST['pe'];
How do I unset all other values except what is in my $selected variable?
Ok, then, assuming your response is in the variable $jsonresponse...
$selected = json_decode($jsonresponse,$assoc=TRUE);
$selected = $selected[$id];
Thank you for your help Charlene. This is how I ended up solving the problem. It is the same concept that Charlene posted just a slightly different format.
$selected = (int)$_REQUEST['pe'];
$save_me = $data[$selected];
unset($data);
$data = $save_me;
print_r($data);
From MySQL row, I have this json formatted data:
$row['details'] =
{
"previous_employer":[
{"employer":"string1","address":"address1"},
{"employer":"string2","address":"address2"},
{"employer":"string3","address":"address3"}],
"profile":[
"firstname":"John",
"lastname":"Adams",
"gender":"male",
"age":"35",
"contact":"123456789"]
}
I want to extract employer and address on the previous_employer array of objects,
but when I do this:
$json = json_decode($row['details'],true); //decode into array
foreach($json['previous_employer'] as $d){
echo "employer:".$d['employer']."<br>address:". $d['address']."<br>";
}
it gives me an error of
Warning: Invalid argument supplied for foreach()
How can I fix this? Pls advise.. thanks!
You JSON is invalid, "profile" must be
An Object:
"profile": {
"firstname": "John",
"lastname": "Adams",
"gender": "male",
"age": "35",
"contact": "123456789"
}
or an Array of Object (here his length == 1)
"profile": [{
"John",
"Adams",
"male",
"35",
"123456789"
}]
or a Simple Array (not associative array/map)
"profile": [
"John",
"Adams",
"male",
"35",
"123456789"
]
Now, your posted code will work as a charm without any modifications ... :)
json_decode() does not necessarily succeed (just imagine you feed it with complete garbage, why should it return something?). You need to do the following error checking:
Verify its return value:
Returns the value encoded in json in appropriate PHP type. Values
true, false and null are returned as TRUE, FALSE and NULL
respectively. NULL is returned if the json cannot be decoded or if the
encoded data is deeper than the recursion limit.
If valid data can be expected to return null some times, call json_last_error() and check whether it's JSON_ERROR_NONE.
Last but not least, you can explore any variable with var_dump(). You don't need to make assumptions about its content.
Im writing a website in php that gets a JSONstring from another php-api Ive created.
The string looks like this:
{
"result": "true",
"results": {
"20": {
"id": "20",
"desc": "a b ct tr",
"active": "1",
"startdate": "2013-04-03",
"starttimehour": "18",
"starttimemin": "0",
"enddate": "2013-04-03",
"endtimehour": "22",
"endtimemin": "0",
"creator": "a"
},
"21": {
"id": "21",
"desc": "test",
"active": "0",
"startdate": "2013-04-04",
"starttimehour": "18",
"starttimemin": "0",
"enddate": "2013-04-04",
"endtimehour": "22",
"endtimemin": "0",
"creator": "a"
}
}
}
Ive found lots of answers on how to get information from a JSONarray but Im not using an array here.
So the question is: how can I get the objects that are labeled 20, 21 and so forth(These numbers are generated by the server so I dont know which ones will be returned).
Or should I rewrite how my api returns the JSON as an array instead. Something like this:
{"result"="true", "results":[{...},{...},{...}]}
$json = json_decode($json_string, True);
foreach($json['results'] as $key => $value) {
// access the number with $key and the associated object with $value
echo 'Number: '.$key;
echo 'Startdate: '.$value['startdate'];
}
I suppose that you are getting the json by POST without any parameter, like
curl http://someapi.somedomain/someresource/ -X POST -d #data.json
so basically
$data = file_get_contents('php://input');
$object = json_decode($data);
print_r($object);
should solve your problem. and $object will be your json object that you post.
You do get the JSON response as a string. That's just the way JSON works. To "convert" the data to a format and structure that is easily accessible, you can use a PHP function called json_decode().
You have two choices when using the function -
To convert the data into an array. json_decode($jsonString,true)
If you use this method, you would access the data like you would for an associative array. $jsonArray['results']['21']
To convert the data into an object. json_decode($jsonString)
With this method, you would use object notation to traverse the data -
$num = 21;
$jsonObj->results->$num
First you decode the string($string) then you can loop through it and get all the properties of the objects. Remember that accessing properties is with ->prop instead of ['prop']. This way you do not have to deal with it in an array manner.
$jsoned = json_decode($string);
foreach($jsoned->results as $o) {
foreach($o as $key => $value) {
echo "The key is: ".$key." and the value is: ".$value."<br>";
}
}
Working example what will print out:
Key is: id and value is: 20
Key is: desc and value is: a b ct tr
Key is: active and value is: 1
etc...
