Calling an array with a string as it's index... $($_Post...)['email']

[eragon]

ok, the title was not proper syntax at all.

heres what i did. for every user that registers for my site their information is stored in an array. their userame is the index. the data i want is the key. one example i share is this:

[php]
<?php
$eragon['password'] = "password" ;
$eragon['f-name'] = "Eragon" ;
$eragon['l-name'] = "Eisert" ;
$eragon['email'] = "[e-mail]" ;
$eragon['notes'] = "ADMIN" ;
?>
[/php]

and to retreive the info i send in a post request with only the username (eragon) and wish it to echo the value of that part of an array. Could somebody please help? Please?

Sincerely,
Eragon

I think the magic word is... Well, I forgot the magic word, but I do remember the symbols that made it up, try :
[PHP]
$eragon = 'user007';

${eragon}['password'] = "password";[/PHP]

Does that juice you up?

[eragon]

lol. 007.

Ok, i see that, nice, very well, but... may i ask... how in entirety am i supposed to do this? where does your code go in?

heres the two parts: the array above and the form.

[___________] {Submit} and thats all thats in the form. the text field is named query, and passes its information through $_POST. i included the file containing the arrays. maybe i should have a better method of storing? and whats the purpose of the $eragon = "user007" ? i know php but im still learning. meh, could you be a tad bit more specific. please? im at a loss... for now, idk... il lhave it rite to a file and il linclude the file that will echo, but that may take a little while... i dont know, any help would be appreciated... maybe str_replace? idk

wait a minute! Can i put the string in replace of the key? and have just a integer as the key? so i can have arrays that look like this:

[php]
<?
$user['eragon'][0] = "password" ;
$user['eragon'][1] = "[e-mail]" ;
// ...
print_r($user) ; //will print ALL the information, which can come in handy.

echo($user[$_POST['query']][0]) ; //is a recipie for disaster...

//and thats how i think it might work...

?>
[/php]

ladies and genties, i have found a solution! make the index of the array a simple string, any string, whether it be yarn or thread, and the first key of the array the username. the second key of the array is the info stored in that array. or you can make the index the info and the key the username, and not need anything else: but remember, you CAN make the key's value equal to a get or post string because the key does not have the $ tag, so the value will be inserted. heres how you call it then:

[php]
<?
//method a: the array.
$user['eragon']['email'] = "[e-mail]" ;
$user['eragon']['password'] = "passer-word" ;
$user['saphira']['password'] = "sappy-fire" ;

//Method a: the calling.
echo('<form action="thispage.php" method="post"><input type="text" name="query"><input type="submit" value="Get \'Er Done!"></form>');
if(isset($_POST['submit'])) {
echo($user[$_POST['query']]['email']);
echo($user[$_POST['query']]['password']); }

//-----

//Method B: the array.
$emails['eragon'] = "e's email" ;
$passes['eragon'] = "e's pass" ;
$passes['saphira'] = "s' pass" ;

//Method B: the calling.
echo('<form action="thispage.php" method="post"><input type="text" name="query"><input type="submit" value="Get \'Er Done!"></form>');
if(isset($_POST['submit'])) {
echo($emails[$_POST['query']]);
echo($passes[$_POST['query']]); }

//and the funny php closing tag
?>
[/php]

so thas why everything, every last little thing, every little tiny microscopic little thing has goooooone... according to plan!

should i make this an article?
