我一直在学习PHP,看到人们如何命名的东西有很多变化.我渴望至少与自己保持一致.

我应该在哪里使用Camel Case以及我应该在哪里使用下划线？

思考:

• 变量/属性:$userid或$user_id或$userID

• 课程:MyCustomClass或myCustomClass

• 功能/方法:my_custom_function()或my_Custom_Function()

任何想法都赞赏.

我正在PHP中创建一个函数,我想在下面传递三个参数:

function lnz_wc_emails_memberreceipients($headers, $object, $order) {

$company = $order->billing_company;

$emailreturn = array (
    'Robin' => "weiltest@weiltest.com",
    'Other' => "beistest@beistest.com, beistest2@beistest.com"
);

$headers = array();
$headers[] = 'Bcc: your name '.$emailreturn[$company];
$headers[] = 'Content-Type: text/html';
return $headers;

}
add_filter( 'woocommerce_email_headers', 'lnz_wc_emails_memberreceipients', 10, 2);

但是,当我尝试这样做时,我得到一个错误,表明我的函数要求3个参数,但只传递了两个.
