Yii2 - How to call ActiveRecord method given its name - php

Question

I have a string variable that contains the model's class name, and I want to call a method on said model using that variable, is that possible??
My code:
foreach($tables as $tables)
{
$table = ArrayHelper::getValue($tables, 'table_name');
$model = \common\models\$table::findAll();
var_dump($model);
}
A simpler version:
$table = "DataAnalysis";
$model = \common\models\$table::findAll();
var_dump($model);
When I run that code, I get the following error:
Exception 'ParseError' with message 'syntax error, unexpected '$table' (T_VARIABLE), expecting identifier (T_STRING)'
Is there anything I can do to call model given the string contained in the variable?

Answer 1

You should simply do,
$model="\\common\\models\\DataAnalysis";
$model::findAll();
OR
$table="DataAnalysis";
$model="\\common\\models\\{$table}";
$model::findAll();
rather than call_user_func() thats too much code for a simple task
Edit
If you need to instantiate the class instead of static call, you can simply do
$table="DataAnalysis";
$model="\\common\\models\\{$table}";
new $model();

Answer 2

You can do it using call_user_func().
// If you have the name of the ActiveRecord class, like in you comment
$class = 'DataAnalysis';
/** #var ActiveQuery $query */
$query = call_user_func($class . '::find');
// Then use the query as you want
foreach($query->each() as $model) {
// Do something with your model
}
If you are not sure if the value in the variable will always be correct, wrap it on a try/catch.
If what you have is the table name, and not the class name, you can try to convert with the Yii inflector camelize method.
use yii\helpers\Inflector;
$tableName = 'some_snake_case_name';
$className = Inflector::camelize($tableName);
/** #var ActiveQuery $query */
$query = call_user_func($className . '::find');
// If you want to filter results
$query->where(...);
// Then use the query as you want
foreach($query->each() as $model) {
// Do something with your model
}
call_user_function docs are here.
