[SOLVED] print_r / foreach

[Aureole]

I know I can use print_r($_SESSION); or something similiar but that outputs something like...

 

Array (

[ 0 ] => Something

[ 1 ] => Something else

)

 

I thought I might be able to use something like...:

 

<?php
$a = $_SESSION[];
foreach($a as $b) {
    echo $b;
}
?>

 

But I get:

 

Fatal error: Cannot use [] for reading in /home/veraci7y/public_html/rev/index.swr3 on line 18

Don't put in the "[]".

 

This should work fine:

<?php
$a = $_SESSION;
foreach($a as $b) {
    echo $b;
}
?>

Ah yes it does, but still it's not showing how I want it to...

 

Ok here's the thing... if I use print_r I get something like this:

Array ( [mem_lname] => 32 char md5 here [mem_dname] => Aureole [mem_pass] => 32 char md5 here [mem_email] => My Email Address [mem_id] => 12 [logged_in] => 1 [mem_group] => 1 [is_admin] => 1 [is_supermod] => 1 )

 

If I use foreach($a as $b) { echo $b; } I get something like this...

 

32 char md5 Aureole 32 char md5 here My Email Address 12 1 1 1 1

 

But without the spaces of course...

 

Now how I'd like for it to show is...

 

mem_lname: 32 char md5 here

mem_dname: Aureole

mem_pass: 32 char md5 here

mem_email: My Email Address

mem_id: 12

logged_in: 1

mem_group: 1

is_admin: 1

is_supermod: 1

 

Is there anyway to do this without actually echoing each of the session variables one by one as there's quite a few more than I posted here...

 

<?php
echo('mem_lname: '.$_SESSION['mem_lname'].'');
echo('mem_dname: '.$_SESSION['mem_dname'].'');
?>

 

I DON'T want to do it like that... I want it to do it dynamically so if (well when) I add new session variables I won't have to change it.

 

Thanks a lot.

You want to do something like:

<?php
foreach($_SESSION as $key => $val)
    echo $key . ' : ' . htmlentities($val,ENT_QUOTES) . "<br>\n";
?>

 

You want to use the htmlentities() function so that if you have any HTML in the values, it will be displayed, not interpreted.

That works a charm and I think I understand it... thanks a lot.

Is it possible to do something similiar with all user defined constants... like I have a bunch of constants I defined and I'd like to do something similar with them...

 

They're in a file called config.swr3 and each is on it's own line so maybe there's a way to go through each line and do it...
