I have the ff code which stores values inputted in form's textfield to a session array which I named "numbers". I need to display the value of the array but everytime I try echo $value; I get an error Array to string conversion in
I used echo var_dump($value); and verified that all the inputted values are stored to the session array.
My goal is to store the user input to an array everytime the user hits the submit button.
How do I correct this?
<?php
session_start();
?>
<html>
<head>
<title></title>
</head>
<body>
<form method="POST" action="index.php">
<label>Enter a number</label>
<input type="text" name="num" required />
<button type="submit">Submit</button>
</form>
</body>
</html>
<?php
if (isset($_POST["num"]) && !empty($_POST["num"])){
$_SESSION['numbers'][] = $_POST["num"];
foreach($_SESSION as $key => $value){
echo ($value);
}
}
?>
Thank you.
