Php printing data from database [duplicate]-CodePudding

I am trying to get the data from the database, but there is a problem printing it out

function getData($connection)
    {
        $query = "SELECT Email FROM SUBSCRIPTIONS";
        $result = $connection->query($query);
        return $result->fetch_all();
    }

$rows = $databaseOperations->getData($connection);
var_dump($rows);
foreach($rows as $row){
    echo('Data: ' . $row . "<br>");
}

And I am getting:

array(2) { [0]=> array(1) { [0]=> string(12) "sfddsffdsfsd" } [1]=> array(1) { [0]=> string(13) "fdsdffsdsfddf" } }
Warning: Array to string conversion in C:\Users\Raitis\Documents\\admin.php on line 47
Data: Array

Warning: Array to string conversion in C:\Users\Raitis\Documents\\admin.php on line 47
Data: Array

So, data is in the $rows, but as result, I get an array? String is essentially array of chars, but PHP shouldn't treat string as an array of chars, because printing it out would be hell.

CodePudding user response：

As the data is output as such:

[
    [[string]]
    [[string]]
]

You could try the following:

foreach($rows as $row){
    echo('Data: ' . $row[0] . "<br>");
}

CodePudding user response：

You cannot echo an Array! each $row inside $rows might or still represent an array

you can:

foreach($rows as $row){
    echo "\nData: \n";
    print_r($row);
    echo "<br>";
}

or:

foreach($rows as $row){
    echo('Data: ' . $row[0] . "<br>");
}

depending on the arrays built and response.
