Symfony 2：如何在PHPExcel中读取excel文件内容

I am using PHPExcel with Symfony 2 and showing the content of an excel file like this:

    $users = array();
    foreach($excel as $i=>$row) {
    if($i !== 1) {          
        array_push($users,array(
            'row'=>$i,
            'name'=>$row['A'],
            'lastname'=>$row['B']
//...and so on

        ));         
    }

}

Question:
How can I show the content using the row name instead of $row['A']..ect?
As $row['name']... I mean the name of the excel row.
Example:
A = name B = email...and so on... I would like to show the content like this:

    $users = array();
    foreach($excel as $i=>$row) {
    if($i !== 1) {          
        array_push($users,array(
            'row'=>$i,
            'name'=>$row['name'],
            'lastname'=>$row['surname']
//...and so on

        ));         
    }

}

I'm pretty sure that I answered this question barely a week ago.... assuming that row #1 contains your headers:

if($i == 1) {
    $headers = $row;
} else {
    $row = array_combine($headers, $row);
    array_push($users,array(
        'row'=>$i,
        'name'=>$row['name'],
        'lastname'=>$row['surname']
        //...and so on

    ));         
}
