意外的＆＃39;如果＆＃39;里面的数组。 Laravel

Question

我试图过滤将在数组内部的值。为此我使用了以下语法：

$selected = array(

        if ($request->annual!=0) {
            'annual' => $request->annual,
        }
        if ($request->registration!=0) {
            'registration' => $request->registration,
        }
        if ($request->monthly!=0) {
            'monthly' => $request->registration,
        }
        if ($request->exam!=0) {
            'exam' => $request->exam,
        }
        if ($request->laboratory!=0) {
            'laboratory' => $request->laboratory,
        }
        if ($request->computer_lab!=0) {
            'computer_lab' => $request->computer_lab,
        }  
    );

但这会引发语法错误。

syntax error, unexpected 'if' (T_IF), expecting ')'

这是什么问题？任何人都可以帮助我吗？

PHP不允许直接在Array体中使用IF。

按以下方式分配数组值：

    $selected = array();
    if ($request->annual != 0) {
        $selected['annual'] = $request->annual;
    }
    if ($request->registration != 0) {
        $selected['registration'] = $request->registration;
    }
    if ($request->monthly != 0) {
        $selected['monthly'] = $request->monthly;
    }
    if ($request->annual != 0) {
        $selected['annual'] = $request->annual;
    }
