PHP: how can I add a specific title to my flash message? - php

Question

I'm working on a flash message with PHP, but I would like to have a specific title for each of my flash message. My container for the flash message is set in my header.php so I can use this system everywhere on my site:
<?php if(isset($_SESSION["flash-message"])): ?>
<?php foreach($_SESSION["flash-message"] as $type => $message): ?>
<div class="alert alert-<?= $type; ?>">
<p><?= $message; ?></p>
</div>
<?php endforeach; ?>
<?php endif; ?>
To execute it, I use this:
$_SESSION["flash-message"]["success"] = "Test";
So, I have that:
Now, I would like to have a title, you know? Something like that:
$_SESSION["flash-message"]["title" = "The title"]["success"] = "The message"
Just something like that. I want the title above the message.

Short answer: use an array or object to store your message with corresponding title.
$_SESSION["flash-message"]["success"] = array("Title", "The Message");
And your code will be like following:
<?php if(isset($_SESSION["flash-message"])): ?>
<?php foreach($_SESSION["flash-message"] as $type => $message): ?>
<div class="alert alert-<?= $type; ?>">
<h2><?= $message[0]; ?></h2>
<p><?= $message[1]; ?></p>
</div>
<?php endforeach; ?>
<?php endif; ?>
EDIT:
And what happens if you have more than one success message? Your current code doesn't support multiple "same type" messages. It should be:
$_SESSION["flash-message"]["success"][] = array("Title", "The Message");
to store multiple "same-type" messages.
EDIT-2:
You can also use object approach - more readable. Also contains multiple message ability I mentioned above.
<?php
$message = new stdClass();
$message->title = "Title";
$message->message = "The Message";
$_SESSION["flash-message"]["success"][] = $message;
?>
<?php if(isset($_SESSION["flash-message"])): ?>
<?php foreach($_SESSION["flash-message"] as $type): ?>
<?php foreach ($type as $message): ?>
<div class="alert alert-<?= $type; ?>">
<h2><?= $message->title; ?></h2>
<p><?= $message->message; ?></p>
</div>
<?php endforeach; ?>
<?php endforeach; ?>
<?php endif; ?>

$_SESSION["flash-message"] should be an array of messages, and a message should have an event_type, a title and a content.
You can model messages in many forms, with classes or associative arrays. See this example message modeled with an associative array:
$a_message = [
"event_type" => "success",
"title" => "The title"
"content" => "The message"
];
This way, you could implement your foreach loop like this:
<?php if(isset($_SESSION["flash-message"])): ?>
<?php foreach($_SESSION["flash-message"] as $message): ?>
<div class="alert alert-<?= $message["event_type"]; ?>">
<h1><?= $message["title"]; ?></p>
<p><?= $message["content"]; ?></p>
</div>
<?php endforeach; ?>
<?php endif; ?>
