Question

我想使用数组作为函数的参数。我希望这是有效的：

function data($array){
    $pdo = Database::connect(); 
    $sql = 'SELECT  *  FROM data ORDER BY id DESC';
    foreach ($pdo->query($sql) as $row) {
       $elements = implode($array);
       echo "Start> ".$elements. "<End";
    }
 }
 $array = array("$row['id']", "$row['name']", "$row['age']", "$someothervariable");      
 data($array);

但我的结果是：Start> <End

编辑：

像这样一切运作良好：

    $pdo = Database::connect(); 
    $sql = 'SELECT  *  FROM data ORDER BY id DESC';
    foreach ($pdo->query($sql) as $row) {
       echo $row['id'];
       echo $row['name'];
       echo $row['age'];
    }

Answer 1

不清楚你要做什么。也许你想要这个：

ini_set('display_errors', 1);
error_reporting(-1);

Answer 2

function data($array){
    $pdo = Database::connect(); 
    $sql = 'SELECT  *  FROM data ORDER BY id DESC';
    foreach ($pdo->query($sql) as $row) {
       $elements = implode($array);
       echo $elements;
    } // this is end of foreach

} // you are missing this braces

 $array = array("$row['id']", "$row['name']", "$row['age']");      
 data($array);
