Issue with my foreach loop - php

Question

So i am trying to validate a form for php.
my contact form is your typical form
<form method="post" action="contact.php">
<table class="contact">
<tr>
<th>
<label for="name">Name</label>
</th>
<td>
<input type="text" name="name" id="name">
</td>
</tr>
<tr>
<th>
<label for="email">Email</label>
</th>
<td>
<input type="text" name="email" id="email">
</td>
</tr>
<tr>
<th>
<label for="message">Message</label>
</th>
<td>
<textarea name="message" id="message"></textarea>
</td>
</tr>
</table>
<input type="submit" value="Send">
now i want to add the php validation to this so i created the following:
if (empty($_POST) === false) {
$errors = array();
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
if(empty($name) === true || empty($email) === true || empty($message) === true) {
$errors[] = 'Please fill out all the required forms!';
} else {
if (filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
$errors[] = 'Sorry please enter a valid email address';
}
if (ctype_alpha($name) === false) {
$errors[] = 'Sorry, name must contain only letters!';
}
}
print_r ($errors);
Now i try to print this out and the array shows the data being imputed into fields, and all the validations work properly. The issue i have is the next step where i add the php to echo out the array in a list.
The code i added above the form was a foreach loop that was suppose to list the error that was shown for any failure of validation:
<?php
if (empty($errors) === false) {
echo '<ul>';
foreach($errors as $error) {
echo '<li>' , $error ,'</li>';
}
echo '</ul>';
}
?>
But now the issue is this: Everytime now i fill out the form the errors don't produce a list they just produce the original array is if the foreach is not being seen.
Any suggestions or help would be great !
thanks guys,

Answer 1

if (count($errors)) echo '<ul><li>'.implode('</li><li>', $errors).'</li></ul>';
else echo 'No errors';
With this are you seeing "No errors"?
Aside, there is no need to do this
if(empty($name) === true)
empty($name) is either true or false. No need to then compare it to true.
if(empty($name))
is perfectly fine, otherwise it's like asking
if ((count(12)>0)==true)!=false)
which would be ridiculous. And actually
if(empty($name.$email.$message))
is far fewer characters, giving the same result as
if(empty($name) === true || empty($email) === true || empty($message) === true)
