mt_rand()...

ichimac · May 6, 2009

I using this function to generate a random number it work awesome however I will like know if there is a way to find out what was the previous number that function created. I will most grateful I could get some help whit this

$min = 1;

$max = 238;

$disallowed = array(4,5,6,8,9,10,12,13,18,19,20,23);

function mt_rand_n($min="1",$max,$disallowed) {

if (!is_array($disallowed)) return false;

$numbers = array_values(array_diff(range($min,$max),$disallowed));

if (count($numbers) < 1) return false;

return $numbers[mt_rand(0,count($numbers) - 1)];

}

$id_rand = mt_rand_n($min, $max, $disallowed);

because what I'm trying to do is this:

the function will created a random number i add that random number in a mysql string to call a user profile and then gives you the option to post a comment, but the way it is at the moment that comment goes to next random number generated not the current one, for example if I have user_id 8, but next number coming is 23 the comment goes to user 23 not 8.

I hope it make sense

Ken2k7 · May 6, 2009

What do you mean the previous number?

premiso · May 6, 2009

Store it in a text file with fopen and fwrite or store it in a DB entry.

ichimac · May 6, 2009

for example $ramdon_id = mt_rand(1,200) ; will pull like 4,8,9,29,89,23, etc....after that first number is generated (4) for example the next one up is 8 I will like to keep that previous generated number on a variable if possible $old_id = (what ever that number was) ....

I hope it make sense

Ken2k7 · May 6, 2009

Store it in an array?

ichimac · May 6, 2009

I already try to store that number to a db for some reason it stores the new value not the old one..

Ken2k7 · May 6, 2009

Show me the code.

ichimac · May 6, 2009

<?php

require_once("includes/session.php");

$conn = dbConnect('query');

$min = 42;

$max = 118;

$disallowed = array(117);

function mt_rand_n($min="1",$max,$disallowed) {

if (!is_array($disallowed)) return false;

$numbers = array_values(array_diff(range($min,$max),$disallowed));

if (count($numbers) < 1) return false;

return $numbers[mt_rand(0,count($numbers) - 1)];

}

$id_rand = mt_rand_n($min, $max, $disallowed);

$sql = "SELECT feed_id,user_nickname,gender,image_normal,user_age,user_location,user_status FROM feed WHERE feed_id='$id_rand' ";

$result = mysql_query($sql) or die(mysql_error());

Please read Forum DOs #4 - http://www.phpfreaks.com/page/rules-and-terms-of-service#toc_forum_dos

Thanks!

ichimac · May 6, 2009

my bad let me do it again Im just sort new on learning this things

ichimac · May 6, 2009

Im sorry I started change colors by hand (ooh boy that was taking for ever) and thing time out I did a prt sc maybe this help better....thanks a lot i really meant that

premiso · May 6, 2009

You could just use the

or

tags around code to highlight it etc. That was what Kev was referring to.

Example:

// Place Code Here

Or:

// Place PHP Code Here

ichimac · May 6, 2009

ooh man I didn't you could do that ...thank you now I know how to color the code

Ken2k7 · May 6, 2009

Your effort on getting those images is most admirable. Most people would not go that far.

I'm still at a lost. Anyone else here understand what ichimac wants to do?

nrg_alpha · May 6, 2009

Preferably

...code...

as

...code...

doesn't colour code things.

<--- likes colours I think code tags are ok for a simple 1 liner example.. but going too much beyond that, I would go with php tags instead.

EDIT - When possible, try to post only the relevant segment of problematic code instead of the entire mountain of it.. can quickly turn people off seeing how this represents them needing to spend extra time trying to decipher things.

ichimac · May 6, 2009

thank you thank you.

what I'm trying to do is this:

the function will created a random number i add that random number into a mysql string to call a user profile and then gives you the option to post a comment, but the way it is at the moment that comment goes to next random number generated not the current one, for example if I have user_id 8, but next number coming is 23 the comment goes to user 23 not 8.

carry_user_id is the user thats sending the message and message for is where the message is going but is not going to the correct user

carry_user_id is the person thats sending the message

article is the message

and message for is the user thats receiving it

Ken2k7 · May 6, 2009

Wow That is funny!

Can you show me the part of the code the defines the variable $article? I'm thinking that is wrong instead of the message_for.

ichimac · May 6, 2009

sure is

// prepare an array of expected items
$expected = array('carry_user_id','feed_id','article', 'message_for');

because the other values are going to correct place is just message_for

ps: holy cow i didn't have to color anything by hand lol

 does, but only within PHP tags.

Ken2k7 · May 6, 2009

Can you either post the entire code or PM it to me? Did you change any values between lines 27 - 176?

ichimac · May 6, 2009

those other lines are just html and css but i'll post

it

 does, but only within PHP tags.
Ah, thanks for the heads up that. Didn't think about nesting those tags together. I always figured it was always either one or the other.

Daniel0 · May 6, 2009

Oh, no that wasn't what I meant.

Compare this:

hello
<?php
echo 'hello';
?>
hello

with:

hello
<?php
echo 'hello';
?>
hello
