如何在mysql的php循环中对项进行求和

Question

<?php
    $query2 = QModel::query("SELECT * FROM transaction");
    while($get2 = QModel::g($query2)) {
        $totalprice = $get2['price'];
        echo array_sum($totalprice);
    }
?>

I get php error:

Message: array_sum() expects parameter 1 to be array, string given

please help thanks

Answer 1

you can use like this :

$totalprice += $get1['price'];
