Question

please help me. i have a problem with my code.
This is code input.php :
<form method="POST" action="simpan.php">
NIM : <input type="text" required placeholder="input NIM" name="nim"/><br/>
Name : <input type="text" required placeholder="input name" name="nama"/><br/>
score : <input type="number" required placeholder="input score between 0-100" name="score"/><br/><input type="submit" value="OK"/>
This is code simpan.php :
<?php
session_start();
$_SESSION['nim'][] = $_POST['nim'];
$_SESSION['nama'][] = $_POST['nama'];
$_SESSION['nilai'][] = $_POST['score'];
header("location:index.php")
?>
and This is code show.php :
<?php
session_start();
foreach($_SESSION as $key)
{
foreach($key as $data => $value)
{
echo "NIM : ",$value." ", "Name : ",$value." ", "Score : ",$value." ";
}
}
?>

And the problem is I want to show the input with format
Nim:
Name:
score:
example = nim:01 name: john score:90
What should I change in show.php in order to appear according to the above format?

Answer 1

#Arif Maulana just change your show.php to like below hope this is what you want:
<?php
session_start();
$echoString = "";
foreach($_SESSION as $key => $sessionArr){
if($key == "nama"){
$echoString .= "name : ";
}
else if($key == "nilai"){
$echoString .= "score : ";
}
else{
$echoString .= $key." : ";
}
foreach($sessionArr as $value)
{
$echoString .= $value." ";
}
}
echo $echoString;
?>

Please check the below example i did https://3v4l.org/CcOOK
<?php
$_POST['nim'] = 'Hrllo';
$_POST['nama'] = 'Data';
$_POST['score'] = '33';
$_SESSION['nim'][] = $_POST['nim'];
$_SESSION['nama'][] = $_POST['nama'];
$_SESSION['score'][] = $_POST['score'];
$string = '';
foreach($_SESSION as $main_key => $key)
{
foreach($key as $data => $value)
{
$string .= $main_key . ":" . $value . ' ';
}
}
$string = rtrim($string, ' ');
echo $string;
