我想过滤将在数组内的值。为此,我使用以下语法:阵列中出现意外的'if'。 Laravel
$selected = array(
if ($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,
}
);
但它是抛出语法错误。
syntax error, unexpected 'if' (T_IF), expecting ')'
这里有什么问题?谁能帮我?
