php - 带有解析错误的 php 函数：语法错误，意外 '('，需要 T_STRING 或 T_VARIABLE 或 '$'

Question

下面的 PHP 函数产生了这个错误： Parse error: syntax error, unexpected '(', expecting T_STRING or T_VARIABLE or '$', on this line that content this code:$obj = new ( );

有谁知道出了什么问题？

function createContextAwareObjectOfClass($className) {
    $className;
    $obj = new (  );
    IApplicationContextAware;

    if (!( $obj instanceof null )) {
        Exception;
        throw new ( '' . 'Non-context aware class "' . $className . '" passed to createContextAwareObjectOfClass' );
    }

    $obj->setAppContext( $this );
    return $obj;
}

Answer 1

我认为

$obj = new (  );
IApplicationContextAware;

应该

$obj = new IApplicationContextAware();
