Question

Im using a select sql statement PDO fetchData,

$user = 'admin';
sql = 'SELECT AccessPage FROM accessrights where UserName = '$user'';

in database the result would look like this:

-----------
Access Page
-----------
 - index

 + create

 - update

And I will store it inside a variable $result

How can I make the $result format to an array just like this?

$result = array('index','create','update');

Another question,

I used the codes in my function: but when I var_dump, it retun a array(0) { } value.

Here is my function:

    $user = CHtml::encode(Yii::app()->user->name);

    $connectionString[0] = Yii::app()->params['dbhandler2'];
    $dbhandler3 = new DBHandler($connectionString[0]);
    $dbhandler3->open();

    $dbhandler3->prepare("SELECT AccessPage FROM accessrights where UserName ='$user'");
    $dbhandler3->execute();
    $this->result2 = $dbhandler3->fetchAllData();
    $dbhandler3->close();

    $yourarrayname = array();
    while ($row = $dbhandler3->fetchAllData()) {
        $yourarrayname[] = $row['AccessPage'];
    }

    $this->access = $yourarrayname;

Answer 1

use the below code

 $user = 'admin';
 $sql = "SELECT AccessPage FROM accessrights where UserName = '$user'";
 $sth = $dbh->prepare($sql);
 $sth->execute();

 /* Fetch all of the values of the first column */
 $result = $sth->fetchAll(PDO::FETCH_COLUMN, 0);
 print_r($result); // the $result will be array  array('index','create','update');
