I am trying to get the index value of two dimensional array and campare it to a user login and password. if the password and username matche, i print out welcome. I know i need a database for this, but I am trying to store the user password and username in two dimensional array then compare the value in the array. Something like this, but is not working. I am new to php and I've been try to get my feet wet.
<?php
$user_name = $_POST['username'];
$user_password = $_POST['userPassword'];
$user_info = array("John"=>"css", "David'=>"html', "Solo"=>"Js");
foreach($user_info as $value=> $user_value) {
}

echo "Welcome ";
}
else {

You also had a ' instead " after html.
/// <?php
$user_name = $_POST['username'];
$user_password = $_POST['userPassword'];
$user_info = array(
"John"=>"css",
"David'=>"html",
"Solo"=>"Js"
);
foreach($user_info as $value=> $user_value) {
if($value === $user_name && $user_value === $user_password) {
echo "Welcome ";
} else {
echo "invalid info";
} //end if
} //end foreach
?> ///
Hopefully this should work for you.

8,378 PointsThank you very much, but can you please explain this part to me
<?php
if($value === $user_name && $user_value === $user_password)// why use $value and user_value
// compare to mine
if(user_info[$value] === $user_name && user_info[$value] === $user_password)
?>
I am guessing the $value is for user name and the $user_password for password?

19,024 PointsWhen you're inside the foreach and you are looping through the $user_info array as $value (key / "name") and $user_value (value / "password") you should use these to run your checks with.
If you use it outside you'll get an error as $value is not anywhere apart from inside the foreach.
