how do I randomize INI elements ?

mduran

Hello,

Here's my problem: I have an INI file like this

[sample1]
sample = sample1.wav

[sample2]
sample = sample2.wav

[sample3]
sample=sample3.wav

...

1 How can I randomize the parsing of this ini so that every time you load a page you get a link to the wav file in random order ?

2 how can I do it so that you DON'T get the same wav file TWICE and you get a 'thanks' page or so when you have visited all wav files ?

thanks for your help.

1 You can do this using random function.
2 When you have shown the resulting link of the random number store it in session and every time you have need of another random number check what's in session!

How do I do this ? can you please iluminate me with an example ???

humble thanks.

$ini_array = parse_ini_file("sample.ini", TRUE);
$random = "sample".mt_rand(1, count($ini_array));

echo $ini_array["$random"][sample];

If you know how many variables/wav exist (and they aren't too much!):

Ex:5 vaw!

<?
session_start();
if (session_is_registered(sess_arr)==false)
{
$sess_arr=array();
session_register(sess_arr);
}

$n=mt_rand (0,4);
while ($sess_arr[$n]!="1")
{
$n=mt_rand (0,4);
}

$sess_ar[$n]="1";
?>
<a href="$n.wav"><?=$n?>.wav</a>

That's to have different link knowing how many wav and filename you have........you can also impliment it after a parsing code!

I don't think I follow... I have done like jayant suggests

$ini_array = parse_ini_file("sample.ini", TRUE);
$random = "sample".mt_rand(1, count($ini_array));

echo $ini_array["$random"][sample];

this is ok, but how do I store $ini_array into a session array ? is it just

session_register($ini_array)

? I tried and it does not work...

Then I have to be able to rest every time from the session array the index I get from

$random = "sample".mt_rand(1, count($ini_array));

isn't it ?. How do I do this ?

Thanks, m.

As the above code this is what you need to put in the session the array $sess_arr

<? 
//Start the session
session_start(); 

//Check if the array sess_arr is in session
if (session_is_registered(sess_arr)==false) 
{
$ini_array = parse_ini_file("sample.ini", TRUE); 

//put it in session
$sess_arr=array();
session_register(sess_arr);
session_register(ini_array);
}

//$random = "sample".mt_rand(1, count($ini_array));

$n=mt_rand (1,count($ini_array));
while ($sess_arr[$n]!="1") 
{ 
$n=mt_rand (1,count($ini_array));
} 

$sess_ar[$n]="1"; 
?>
<a href="sample<?=$n?>">sample<?=$n?></a>
