Yii model to array? - arrays

Question

How can I convert the result of Trips::model()->findAll() to an array?

Answer 1

I'm going on the assumption here that you only need to retrieve just the bare arrays, and not any associated model objects.
This will do it:
$model = Trips::model();
$trips = $model->getCommandBuilder()
->createFindCommand($model->tableSchema, $model->dbCriteria)
->queryAll();
This is like the Yii::app()->db->createCommand('SELECT * FROM tbl')->queryAll(); examples, except:
It'll ask the model for the table name; you won't need to write the table name in both the model and the query.
You can call scoping functions on $model first, eg.
$model = Trips::model()->short()->destination('Austin, TX');
Doing this means you can use the model's existing query shortcuts, instead of putting them in the query directly.
In contrast, the $trips = Trips::model()->findAll(); (using foreach) is a bit wasteful, in that you're pulling the rows from the database, setting up a bunch of objects, and then throwing them all away. It'll work fine for small result sets, but I wouldn't use that if you're looking at a long list of Trips.
Caveat:
If this is just a quick prototype, though, by all means use the createCommand() or findAll()-and-loop examples.

Answer 2

This is the right way to do, it follows Yii conventions
$trips = Trips::model()->findAll();
$arr = array();
foreach($trips as $t)
{
$arr[$t->id] = $t->attributes;
}
This is used when you have complex queries, those you find difficult to create with Yii conventions.
Yii::app()->db->createCommand('SELECT * FROM tbl')->queryAll();
For example, when you need to pass all the data from the model to an array. You cannot pass it directly as it does pass some ActiveRecord data information that you don't need.

Answer 3

This is same.
$array = CHtml::listData(Trips::model()->findAll(), 'trip_id', 'trip_name');

Answer 4

Easy and simple way: I use listData() method to make array to dropdown menus, and I think this will help you.. check this example:
code:
<?php
/*you can use here any find method you think
proper to return your data from db*/
$models = Trips::model()->findAll();
// format models resulting using listData
$tripsArray = CHtml::listData($models, 'id', 'name');
print_r($tripsArray);
?>
output:
array(
'1'=>'trip1',
'2'=>'trip2',
'3'=>'trip3',
)

Answer 5

$model = Trips::model()->findAll();
$arr = CHtml::listData($model, 'trip_id', 'trip_name');
var_dump($arr);
CHtml::listData() will return an array value.

Answer 6

You can create collections CMap continue to work with her
$collections = new CMap();
foreach (YourModel::model()->findAll(['index' => 'id']) as $key => $row) {
$collections->add($key,$row->attributes);
}
var_dump($collections ->toArray());

Answer 7

I'm pretty sure you can do this:
$trips = Trips::model()->findAll();
$arr = array();
foreach($trips as $t)
{
$arr[$t->id] = $t->attributes;
}
I'm assuming you have the attribute 'id' as your model's primary key.

Answer 8

i use $array = CJSON::decode(CJSON::encode($model)); to convert $model to $array.

Answer 9

You can use this.
$Trips::model()->findAll(array('index'=>'trip_id'));
if(count($Trips)>0)
{
$TripsArrayList=array();
foreach($Tripsas as $singleTrip)
{
$TripsArrayList[]=array('trip_id'=>$singleTrip->trip_id,'name'=>$singleTrip->name);
}
}
Your output will be
Array
(
[0] => Array
(
[trip_id] => 1
[name] => Nashik
)
[1] => Array
(
[trip_id] => 2
[name] => Puna
)
[2] => Array
(
[trip_id] => 3
[name] => Mumbai
)
)

Answer 10

$cats = Category::model()->findAll();
$count_cats = count($cats);
if($count_cats > 0){
$arr_category = array();
foreach($cats as $cat)
array_push($arr_category,$cat->attributes);
}
print_r($arr_category);
-> result
Array(
[0] => Array
(
[cat_id] => 2
[title] => Đương đại
[title_full] => Đương đại
[desc] =>
[alias] => duong-dai
[p_id] => 0
[type] => 1
[status] => 1
[sort_order] => 2
[selected] => 0
)
[1] => Array
(
[cat_id] => 164
[title] => Nhiệt đới
[title_full] => Nhiệt đới
[desc] =>
[alias] => nhiet-doi
[p_id] => 0
[type] => 1
[status] => 1
[sort_order] => 0
[selected] => 0
)
[...])

Answer 11

Assuming from your question that you want all the attributes, a more compact solution to give you all attributes hashed by id, you can use CActiveRecord's 'attributes' pseudoproperty as follows:
CHtml::listData(Trips::model()->findAll(), 'id', 'attributes')

Answer 12

In yii2 you can use asArray()
$someArray = Sometable::find()->select(['id', 'name', 'role'])->asArray()->all();

Answer 13

Use DAO for arrays
$array = Yii::app()->db->createCommand('SELECT * FROM tbl')->queryAll();

Answer 14

Don't used CHtml::listData for this. It has to be used for other purposes.
There is an index property of CDbCriteria which is suitable for you requirement.
//1st option
Trips::model()->findAll(array('index'=>'trip_id'));
//2nd option
$c = new CDbCriteria();
$c->index = 'trip_id';
Trips::model()->findAll($c);

Answer 15

Use simply:
$trips = Trips::model()->findAll();
$trips_array = CJSON::decode(CJSON::encode($trips));
Note: This is not good way but returns array
