Arrays and in_array();

[intenz]

How can I search an array like this...

Array ( [0] => Array ( [username] => tannkrem [password] => sfddsggds ) [1] => Array ( [username] => jonas [password] => sdfgsdgds ) [2] => Array ( [username] => leifur [password] => sadsdafds ) [3] => Array ( [username] => jon [password] => adskdsahj ) [4] => Array ( [username] => prump [password] => jkæljækjk ) )

The in_array(); function doesn't seem to work too well. :/

When I enter e.g. the username 'tannkrem' and the password 'sfddsggds' it displays 'Unauthorized.'.

Can you help me? :/

The whole code...

<?
$skra = file('users.txt');
for($i = 0; $i < count($skra); $i++)
{
        $temp = explode("\t",$skra[$i]);
        $users[$i]['username'] = $temp[0];
        $users[$i]['password'] = $temp[1];
}
print_r($users);
echo '<br><br>';
#die();
?>
<form action="" method="post">
Username:<br>
<input type="text" name="username"><br>
Password:<br>
<input type="password" name="password"><br><br>
<input type="submit" name="submit">
</form>
<?
if($_POST['submit'])
{
        if($_POST['username'] && $_POST['password'])
        {
                for($i = 0; $i < count($users); $i++)
                {
                        if(in_array($_POST['username'],$users)) $user_login = TRUE;
                        if(in_array($_POST['password'],$users)) $pass_login = TRUE;
                }
                if(!$user_login || !$pass_login)
                {
                        die('<b>Unauthorized.</b>');
                }
                else
                {
                        echo 'Private stuff here';
                }
        }
}
?>

I forgot to paste the content of users.txt ...

tannkrem<TAB>sfddsggds
jonas<TAB>sdfgsdgds
leifur<TAB>sadsdafds
jon<TAB>adskdsahj
prump<TAB>jkæljækjk

Hey,

As your using an assoc. array in_array won't work as you expect. You can use this function to do what you need:

function in_multi_array( $needle,$haystack )
{
    $in_multi_array = false;
    if( in_array($needle,$haystack) )
    {
        $in_multi_array = true;
    }
    else
    { 
        for( $i=0; $i<sizeof($haystack); $i++ )
        {
            if( is_array($haystack[$i]) )
            {
                if( in_multi_array($needle, $haystack[$i]) )
                {
                    $in_multi_array = true;
                    break;
                }
            }
        }
    }
    return $in_multi_array;
}

It will return true if it finds a correct match, or false if there is not a match...

Hey,

I had a spare few minutes so i wrote this up. It's the same in principal only i did not read data from a file:

<?php

$users[0]["username"] = "elfyn";
$users[0]["password"] = "pass";

$users[1]["username"] = "meme";
$users[1]["password"] = "poopoo";

?>

<?php

function in_multi_array( $needle,$haystack )
{
    $in_multi_array = 0;
    if( in_array($needle,$haystack) )
    {
        $in_multi_array = 1;
    }
    else
    {
        for( $i=0; $i<sizeof($haystack); $i++ )
        {
            if( is_array($haystack[$i]) )
            {
                if( in_multi_array($needle, $haystack[$i]) )
                {
                    $in_multi_array = 1;
                    break;
                }
            }
        }
    }
    return $in_multi_array;
}

?>

<form action="" method="post">
Username:<br>
<input type="text" name="username"><br>
Password:<br>
<input type="password" name="password"><br><br>
<input type="submit" name="submit" value="Login">
</form>

<?php

if($_POST["submit"])
{
    if($_POST["username"] && $_POST["password"])
    {
        if( in_multi_array($_POST["username"],$users) )
        {
            $user_login = 1;
        }
        else
        {
            $user_login = 0;
        }
        if( in_multi_array($_POST["password"],$users) )
        {
            $pass_login = 1;
        }
        else
        {
            $pass_login = 0;
        }
        if(! $user_login && ! $pass_login)
        {
            echo "<b>Unauthorized.</b>\n";
        }
        else
        {
            echo "Private stuff here\n";
        }
    }
}

?>

Hope this helps...
