I have filled a mongodb-collection with the following values (identifer = myvar):
array (size=10)
0 => string 'B00LHILHS8' (length=10)
1 => string 'B00WSCCMV8' (length=10)
2 => string 'B00MA15OK8' (length=10)
However - findBy(['myvar' => 'B00LHILHS8']) returns the document as wanted. But findBy(['myvar' => ['B00LHILHS8', 'B00WSCCMV8']]) returns an empty result.
I am not sure, if this is right. As the Doctrine Manual - Working with objects - By Simple Conditions mentions, that it should be possible to pass an array for the findBy() method.
Should i use the query-builder instead?
use doctrine-mongodb-odm with Conditional Operators [link]
try:
$qb = $dm->createQueryBuilder('Entity')
->field('myvar')->in(array('B00LHILHS8', 'B00WSCCMV8'));

I have a php codeigniter web app that has a mongo db backend.
i'm stuck for now using the mongoclient library for php.
I often have to run commands like this:
$result = $collection->find(
array("didnum" => $didnum)
);
$result = iterator_to_array($result);
Assuming that $result looks like this:
array (size=1)
'5824b9376b6347a422aae017' =>
array (size=10)
'_id' =>
object(MongoId)[22]
public '$id' => string '5824b9376b6347a422aae017' (length=24)
'users' =>
array (size=1)
0 =>
array (size=2)
...
'rules' =>
array (size=1)
0 =>
array (size=5)
...
'id' => string '5824b9376b6347a422aae017' (length=24)
'last_assigned' => string 'missing' (length=7)
'widgetnum' => string '+18455100023' (length=12)
'location' => string 'missing' (length=7)
What is the easiest way to access the location field?
In other words, in cases where I know there will only be one result, I'm still finding that i have to loop through $result because the array is an associative one, and i won't know what the ID is.
Just wondering if there's an easier way to do this?
Thanks.
I'm not very much into PHP, but findOne method seems to exist for PHP binding as well as other languages' bindings
You can use $collection->findOne instead of $collection->find
I'm using a sphinx bundle (timewasted SphinxSearchBundle) in a symfony 2 app (https://github.com/timewasted/Search-SphinxsearchBundle) (based on the PHP API)
it works great as long as I don't try to use the SPH_MATCH_EXTENDED.
Here's a code sample
$sphinxSearch = $this->get('search.sphinxsearch.search');
$sphinxSearch->setMatchMode(SPH_MATCH_EXTENDED);
$searchResults = $sphinxSearch->search("#typemesure_id 2", $index);
But the result is always empty, and it seems that my field (#typemesure_id) is considered as a word :
'words' =>
array
'typemesure_id' =>
array
'docs' => string '0' (length=1)
'hits' => string '0' (length=1)
2 =>
array
'docs' => string '4169' (length=4)
'hits' => string '5714' (length=4)
Does anyone konws whats wrong in my request ?
Can anyone post an exemple of working extended query working with this bundle?
My goal is to get a condition like "#(user1,user2,user3) 15"
Thanks for your help
Notes:
the SPH_MATCH_ALL & SPH_MATCH_ANY are working fine.
The setFilter() method is also working
Looking at the function defition...
public function search($query, array $indexes, array $options = array(), $escapeQuery = true)
It will automaticlly escape the query, so the # will be getting escaped. Need to pass false as fourth param
I'm looking for a way to access this JSON file data. What I'm interested in is to extract the property named documentjsonblob, as below.
object(Quadrem\Model\Order)[201]
protected '_dateCreated' => null
protected '_buyerCode' => null
array (size=2)
2415 =>
array (size=23)
'#storeid' => string '813' (length=3)
'#active' => string '1' (length=1)
'#created' => string '2013-11-25 12:28:21' (length=19)
'documentjsonblob' => string '{"HEAD":{"ORDERSEQUENCE":"0","TOTAL_TAX":7.9,"TOTAL_AMOUNT":86.9,"NUMBER":"AKMon3","TYPE":"NB","TYPE_NAME":"Standard PO","SUPPLIER":"0000002122","CREATED":"2013-04-29T12:00:00Z","CONTRACT_NUMBER":"","EXTERNAL_REFERENCE":"","CONTACT_PERSON":"Caroline Howlett","COMMENT":[""],"CURRENCY":"AUD","DELIVERY_TERMS":"DeliveryCondition|","PAYMENT_TERMS":[{"TEXT1":"21st day of next month after receipt"}],"NET_VALUE":79.0,"DELIVERY_ADDRESS":{"NAME_1":"KGTP FACILITY","NAME_2":"GAS TREATMENT PLANT","NAME_3":"KGPF","POSTAL_CODE":"6714","CITY":"Karratha","STREET":"Withnell Bay","REGION":"AUWA","REGION_NAME":"AUWA","COUNTRY":"AU"}]}' (length=3029)
'documenttype' => string 'PO' (length=2)
1890 =>
array (size=23)
'#storeid' => null
'#active' => null
I'm not quite sure which kind of an encoded JSON file this is by the way it looks. Would appreciate it if somebody could help.
Thanks.
Since in the comment you have mentioned it is the out put of var_dump and you want to get documentjsonblob, let's follow this:
On first line you have object(Quadrem\Model\Order)[201], that means you var_dumped an object, say $my_obj
On line four array (size=2) says you have an array, and what you need is located in the first element of the array, so $my_obj[0]
$my_obj[0] holds an associative array, and the desired index is documentjsonblob, so we can get the String representation as:
$my_arr = $my_obj[0];
$json_str = $my_arr['documentjsonblob'];
Now $json_str holds the String representation, to convert it to an PHP object:
$json_obj = json_decode($json_str);
So now $json_obj holds the object you want.
Currently I'm looping through a quite large data set. This multidimensional array needs to be grouped by specific array values of its sub arrays. As this is a holiday project, I want to do deepen my knowledge and make more use of PHPs Iterators. Point is, that I don't know how to transform a numeric multi-dimensional Array into a multi-dimensional array with associative keys.
Shortened example (GeoJSON to Array)
array (size=4)
'type' => string 'FeatureCollection' (length=17)
'features' => // THIS is the actual array
array (size=207)
0 => // Sub-Arrays like this one are repeating
array (size=5)
'type' => string 'Feature' (length=7)
'geometry' =>
array (size=2)
'type' => string 'LineString' (length=10)
'coordinates' =>
array (size=410)
0 =>
array (size=2)
0 => float 16.359980888872
1 => float 48.208437070943
// etc.
'geometry_name' => string 'SHAPE' (length=5)
'properties' =>
array (size=5)
'OBJECTID' => int 273
// This/"LBEZEICHNUNG" is the part I want to order/summon
// all further "geometry"-parts by
'LBEZEICHNUNG' => string '13A, 2, 86, U3' (length=1)
'LTYP' => string '1' (length=1)
'LTYPTXT' => string 'Tramway' (length=12)
'SE_ANNO_CAD_DATA' => null
'id' => int 1
The features array is what holds the actually looped datasets. And LBEZEICHNUNG are the values (single or comma separated) I want to sort/order by.
To make an example:
// Original values:
'LBEZEICHNUNG' => string '13A, 2, 86, U3'
// Now split them and push the features into new keys that have those values:
'13A' => array(
0 => // Sub-Arrays like this one are repeating
array (size=5)
'type' => string 'Feature' (length=7)
'geometry' =>
array (size=2)
'type' => string 'LineString' (length=10)
'coordinates' =>
array (size=410)
0 =>
array (size=2)
0 => float 16.359980888872
1 => float 48.208437070943
// etc.
'geometry_name' => string 'SHAPE' (length=5)
'properties' =>
array (size=5)
// "OBJECTID" now is obsolete
// "LBEZEICHNUNG" is now obsolete
'LTYP' => string '1' (length=1)
'LTYPTXT' => string 'Tramway' (length=12)
'SE_ANNO_CAD_DATA' => null
// "id" now is obsolete as well
),
"2" => // gets the same values as "13A"
// same goes for "86" and "U3"
Now every sub array that would have either 13A, 2, 86 or U3 in ["properties"]["LBEZEICHNUNG"], would push its geometry to the end of the already existing subarray/sub-Iterator.
So far I only got a basic recursive Iterator set up, that runs through all leaves.
$data = new \RecursiveArrayIterator( $fileContents );
foreach( new \RecursiveIteratorIterator( $data ) as $key => $value )
{
// foo. bar. dragons.
}
Point is that I can't really figure out how to assign new keys from values in the Iterator. I already tried using a RecursiveFilterIterator and failed gracefully as its simply not intended to do this. Quite frankly: I'm lost as I either can't find the right Iterator to use or I simply ain't know enough about Iterators yet.
I got a working solution with nested foreach-es pushing into another Array. As this is my holiday project I want to learn, hence the Iterator solution, which I hope is more maintainable in the long turn.
Edit: Link to the original Geo-JSON data set CC-BY-SA 3.0/AUT - Data provided by the City of Vienna. Other formats can be found here.
If I understood correctly, you want to sort/ or group the array based on that "LBEZEICHNUNG" key, and use PHP iterators. In order to do that, you have to traverse the entire array, and build a new one that holds the values grouped by that key. This is simple foreach logic.
Iterators shine when you want to traverse a data collection and fetch the data during traversal (or alter it).
In this case, you are fetching the data outside of the iterator (json_decode ?), so that makes iterators kind of pointless - unless you need to do more than just sorting. If you do, I'd suggest you store that data in a format that allows you to easily fetch sorted sets, like a database, then you can use iterators to their full potential.
One way to group the routes is to use basic OOP:
class Route{
protected $trams = array();
// add other route properties (type, geometry etc.)
public function assignTo(Tram $line){
if(!in_array($line, $this->trams, true))
$this->trams[] = $line;
}
public function getTrams(){
return $this->trams;
}
}
class Tram{
public $name;
protected $routes = array();
public function __construct($name){
$this->name= $name;
}
public function addRoute(Route $route){
$this->routes[] = $route;
$route->assignTo($this);
}
public function getRoutes(){
return $this->routes;
}
}
Example:
$trams = array();
foreach($data as $routeData){
$route = new Route();
$tramNames = explode(', ', $routeData['features']['properties']['LBEZEICHNUNG']);
foreach($tramNames as $name){
if(!isset($trams[$name]))
$trams[$name] = new Tram($name);
$trams[$name]->addRoute($route);
// set other route properties...
}
}
You can use usort to sort your multi-dimensional array based on sub-values:
$JSON = iconv('UTF-8', 'UTF-8//IGNORE', utf8_encode(file_get_contents("http://data.wien.gv.at/daten/geoserver/ows?service=WFS&request=GetFeature&version=1.1.0&srsName=EPSG:4326&outputFormat=json&typeName=ogdwien:OEFFLINIENOGD")));
$geoarray = json_decode($JSON, true);
$myarray = $geoarray["features"];
function cmp($a, $b) {
return $a["properties"]["LBEZEICHNUNG"] - $b["properties"]["LBEZEICHNUNG"];
}
usort($myarray, "cmp");
print_r($myarray);
I am using Code Igniter and I get following data structure after executing a query at DB
array
'application' =>
array
0 =>
object(stdClass)[19]
public 'app_id' => string '16' (length=2)
public 'app_name' => string 'dddddddd' (length=8)
public 'app_title' => string 'sdfsdf' (length=6)
public 'app_comments' => string 'sdfsdf' (length=6)
public 'active_flg' => string 'N' (length=1)
I know one way to access the values is
foreach($application as $key => $value)
$value->app_id
But I know that I will get only one record each time so I want to access the elements without using foreach.
I have tried to $application->app_id and $application['app_id'] but I keep getting error.
Can anybody please help me to understand how to access the data directly??
You are using multidimensional mixed type of array, with numeric indexing on the second level. SO, while accessing the values, you have to use them too. Like
echo $array['application'][0]->app_id;
A simple example to show you the structure of your array and how you might access it...
$objArray = array('app_id' => 7, 'app_name' => 'apps demo', 'app_title' => 'apps demo title');
$applicationArray = array('application' => array((object)$objArray));
// access the array
print $applicationArray['application'][0]->app_id;
Are you getting that result by doing the following?
$res = $this->db->query('select * from application limit 1')->result();
If so, you can put that result into an object by doing:
$app = $this->db->query('select * from application limit 1')->row();
This way you can access the properties as follows:
echo $app->app_id;
You should check out codeigniters manual on getting results.
