I'm trying to learn json in php. Here's my json result from a ElasticSearch query.
{
"took" : 1,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : null,
"hits" : [ {
"_index" : "xenforo",
"_type" : "post",
"_id" : "1816069",
"_score" : null,
"sort" : [ 1365037907 ]
} ]
}
}
I assume that my php code will look something like this:
$myData = json_decode($result);
foreach($myData->hits as $var) {
$post_id[] = $var->_id;
}
Been looking for the answer for hours, I sure do appreciate any help. Thank you.
Edit: Here is the answer:
foreach($myData->hits->hits as $var) {
$post_id[] = $var->_id;
}
You're one ->hits short if you look at your JSON structure...
{
"hits" : {
"hits" : [ {
"_id" : "1816069",
$myData = json_decode($result);
foreach($myData->hits->hits as $hit) {
$post_id[] = $hit->_id;
}

I need to pass on a variety of variables from mysql queries to create a json file and post every block whenever $sku changes. I can retrieve the data just fine, but when I try to use json_decode, it either says syntax error or returns null, or worse, treats everything as text.
$updatedData = '{
"items" : [
{
"barcode" : $barkod,
"title" : $title,
"productMainId" : $sku,
"brandId" : $marka,
"categoryId" : 387,
"stockCode" : $sku,
"dimensionalWeight" : 0,
"description" : $desc,
"vatRate" : 0,
"images" : [
{
"url" : $image0link
}
],
"attributes" : [
{
"attributeId" : 343,
"attributeValueId" : $gender
},
{
"attributeId" : $mekanizma1,
"attributeValueId" : $mekanizma2
},
{
"attributeId" : $kasasekli1,
"attributeValueId" : $kasasekli2
},
{
"attributeId" : $camcinsi1,
"attributeValueId" : $camcinsi2
},
{
"attributeId" : $camsekli1,
"attributeValueId" : $camsekli2
},
{
"attributeId" : $kordonmlz1,
"attributeValueId" : $kordonmlz2
},
{
"attributeId" : $kordonrengi1,
"attributeValueId" : $kordonrengi2
},
{
"attributeId" : $kasacap1,
"attributeValueId" : $kasacap2
},
{
"attributeId" : $kasarengi1,
"attributeValueId" : $kasarengi2
},
{
"attributeId" : $sugecirmezlik1,
"attributeValueId" : $sugecirmezlik2
},
{
"attributeId" : $kasamlz1,
"attributeValueId" : $kasamlz2
},
{
"attributeId" : 47,
"customAttributeValue" : $kadranrengi
}
],
"cargoCompanyId" : 1
"shipmentAddressId" : 409558
"returningAddressId" : 409558
}
]
}';
{$json = json_decode($updatedData, true);
if (is_null($json)) {
die("Json decoding failed with error: ". json_last_error());
}
var_dump($updatedData);}
I'd appreciate any help. Thanks in advance.
Ok, I'm hoping this is not the same as other questions and I have looked for similar but can't find the answer... so here goes.
I get a JSON file and need to read the contents into a database. No sweat.
However I am having issue with reading the lowest levels as there can be a duplicate array.
I have all the data down to "comp".
Sample JSON file:
{
"code" : 0,
"format" : 2,
"s_data" :
{
"name" : "Lance",
"club" : "Southern"
},
"d_data" :
{
"errorcode" : 3,
"errormsg" : ""
},
"timing" :
{
"elapsed_time" : "08:29",
"elapsed_time_secs" : 509,
"comp" :
[
{
"no" :
[
{
"sno" : 0,
"xpos" : 230.9,
"ypos" : 97.2
},
{
"sno" : 1,
"xpos" : 132.4,
"ypos" : 258.3
},
{
"sno" : 2,
"xpos" : 135.5,
"ypos" : 176.7
},
]
},
{
"no" :
[
{
"sno" : 0,
"xpos" : 250.9,
"ypos" : 92.2
},
{
"sno" : 1,
"xpos" : 182.4,
"ypos" : 158.3
},
{
"sno" : 2,
"xpos" : 145.5,
"ypos" : 192.7
}
]
}
]
}
}
So I want to now read the "no" data, but just the first instance of "no"... that is: sno, xpos, ypos foreach "sno" entry..
I'm thinking:
$mydata = json_decode(sample.json, true);
foreach($mydata->comp[0]->no as $values)
{
echo $values->sno . "\n";
}
I get nothing back.
Any kind assistance appreciated.
If you decode it in an associative array, you have to use it according, try this code:
foreach($mydata['timing']['comp'][0]['no'] as $values)
{
echo $values['sno'] . "\n";
}
where all accesses to $mydata are using array style notation.
You have also to consider that the one posted is not a valid JSON string.
EDIT 20160122:
JSON string is now valid.
I am having some issues parsing a json file from Jenkins using PHP
{
"actions" : [

I have tried doing the following
//Read in JSON object
$json_file2 = file_get_contents('url.com/json');
//Decode JSON file
$test = json_decode($json_file2); //object
//print_r($json_file2);
echo $test->causes;
I am also trying to access the different sections in "buildsByBranchName". I have tried many different variations of the code above, but I keep getting "Undefined property: stdClass" errors.
You are not accessing that value properly. causes resides under actions which is an array. Your code also won't work because causes is an array.
// This is an array so you can't use echo here.
$causes = $test->actions[0]->causes;
// echo out the shortDescription
echo $causes[0]->shortDescription;
or
echo $test->actions[0]->causes[0]->shortDescription;
I got this kind of document:
{
"_id" : ObjectId("54ad5c3b9a703a3c088b4567"),
"hard" : 750,
"coordinates" : {
"x" : 0.2388169910939489,
"y" : 0.7996551291084174
},
"indicator" : 500,
"networkIdList" : {
"networkIdData" : [
{
"networkId" : "abc123",
"type" : "SomeNetwork"
},
{
"networkId" : "123asdf",
"type" : "AnotherNetWork"
},
{
"networkId" : "abc123",
"type" : "OneMoreNetwork"
}
]
}
}
And I need to perform a query to find the document that have "networkId" = "abc123" AND "type" = "SomeNetwork".
I have tried With this instruction:
$this->documentManager->createQueryBuilder('Mydocument') ->field('networkIdList.networkIdData.$.networkGamingId')->equals('abc123') ->field('networkIdList.networkIdData.$.type')->equals('')
->getQuery()
->execute());
But the cursor return no data.
I also try with
->where("function() {return this.networkIdList.networkIdData.$.networkGamingId == 'abc123'}")
but in this case i got an error that says the Object $ has no propierties.
And I need to perform a query to find the document that have "networkId" = "abc123" AND "type" = "SomeNetwork"
$qb = $dm->createQueryBuilder('Foo')
->field('networkIdList.networkIdData.networkId')->equals('abc123')
->field('networkIdList.networkIdData.type')->equals('SomeNetwork');
I understand how to parse json with PHP, however I don't understand how to read it with the eye. Can someone please help me understanad this?
Here is my code
<?php
$json = file_get_contents('json.txt');
$json_output = json_decode($json);
foreach ( $json_output->query as $stf )
{
echo "{$stf->response->domains->name}\n";
}
?>
Here is a sample of the json result
{ "query" : { "host" : "test.com",
"tool" : "pro"
},
"response" : { "domain_count" : "13",
"domains" : [ { "last_resolved" : "2012-01-11",
"name" : "test1.com"
},
{ "last_resolved" : "2012-01-11",
"name" : "test2.com"
},
As you can see I tried query->response->domains->name and it didn't work.
How would I tried name?
Thank you in advance
query->response->domains is an indexed array, so you need to get an index, say [0], and then get the ->name from that.
echo $stf->response->domains[0]->name."\n";
foreach ( $json_output->query->response->domains as $domain )
{
echo $domain->name;
}
Study this http://json.org/
If you're trying to read it by eye, it might help to reformat:
{
"query" : {
"host" : "test.com",
"tool" : "pro"
},
"response" : {
"domain_count" : "13",
"domains" : [{
"last_resolved" : "2012-01-11",
"name" : "test1.com"
},{
"last_resolved" : "2012-01-11",
"name" : "test2.com"
}]
}
}
