Question

有人使用了我的代码，并说对他们有用，但是由于某些原因，在我的Mac上，每当我使用表单时，它都不会追加到我目录中的CSV文件中。这是一个名为data.csv的空文件。这是我的代码：

<?php
$error = '';
$name = '';
$email = '';
$subjects = '';

function clean_text($string)
{
 $string = trim($string);
 $string = stripslashes($string);
 $string = htmlspecialchars($string);
 return $string;
}

if(isset($_POST["submit"])) {
    $name = clean_text($_POST["user_name"]);
        if(!preg_match("/^[a-zA-Z ]*$/",$name)) {
            $error .= '<p><label class="text-danger">Only letters and white space allowed</label></p>';
        }
    if(empty($_POST["user_mail"])) {
        $error .= '<p><label class="text-danger">Please Enter your Email</label></p>';
    } else {
        $email = clean_text($_POST["user_mail"]);
        if(!filter_var($email, FILTER_VALIDATE_EMAIL)) {
            $error .= '<p><label class="text-danger">Invalid email format</label></p>';
        }
    }
    $subjects = clean_text($_POST["user_subjects"]);
    
    if($error == ''){
        $file_open = fopen("data.csv", 'a');
        $num_rows = count(file("data.csv"));
        $form_data = array(
            0 => $name,
            1 => $email,
            2 => $subjects
        );
        fputcsv($file_open, $form_data);
        $error = '<label class="text-success">Thank you for contacting us</label>';
        $name = '';
        $email = '';
        $subjects = '';
    }
}
