 Oops I forgot to also ask, what would happen if each category had a different number of elements? How would I use count then, b.c if one Array had 5 elements and another 2, then this could cause problems.

Thanks,

 i guess mine is the shortest one. i do not have a url, because im doing this on some local server, which allows me to view it without uploading it, and i do not want to take the time to.<br>main one.


<?
mt_srand (time());
require ("randomquote.php");
$rand = mt_rand (1, count ($banners));
$rand--;
print ("<img src=\"$banners[$rand]\">");


?>




<?
//im lazy
$banners = array ("ed.gif", "me.jpg", "bullet.gif", "flag.jpg");

 Ahkorahil, hey,
you should just have to enter the url, just type it out, the bulletin board automatically reads it as a url

 Woohoo, This was easy compared to the #3 advanced with the multidimensional assignment.
However, I did have to look back now and then for the proper syntax.....

Index page:


<html>
<head><title></title></head>
<body>

<? require("assignment4.php"); ?>

</body>
</html>



<?
/* BASIC Assignment #4:
Write a script to rotate banners kept inside an array
stored using a separate file and using require to bring
into the main script which does the rotation. */

// Set path to images
$image_path = 'gifs';

// Set banner array
$banner_array = array('1.gif','2.gif','3.gif','4.gif','5.gif','6.gif','7.gif');

// Set random Seed
mt_srand(time());

// Set static min & random max values, by counting the
// imags in the array, to randomly display
$random_banner =(mt_rand(1, (count($banner_array)))-1);

// Print the random banner
print("<img src=\"$image_path/$banner_array[$random_banner]\">");

?>




...and it works too!

 Ok..here we go :

require-file :

<?php
$banners=array ('bannerimage1.jpg','bannerimage2.jpg','bannerimage3.jpg','bannerimage4.jpg');
mt_srand(time());
$random= mt_rand(1, (count($banners)));
$random--;
?>



<?php
require("lesson4require.php");
print "<center><img src=$banners[$random]></center>";
?>

Going advanced now....

 I have the following script:
<HTML>
<BODY>
<?require("D:\PROGRAME INSTALATE-FUNCTIONALE\PHP Designer 2005\proiecte d'ale mele\random_quote");
?>
</BODY>
</HTML>
The random_quote file is:
<?
$pictures=array("D:\week4\poza_1.jpg","D:\week4\poza_2.jpg","D:\week4\poza_3.jpg","D:\week4\poza_4.jpg","D:\week4\poza_5.jpg");
mt_srand(time());
$random_index=mt_rand(1,count($pictures)-1);
print("<img src=\"$pictures[$random_index]\">");
?>
It gives me the following error:
Warning: main(D:\PROGRAME INSTALATE-FUNCTIONALE\PHP Designer 2005\proiecte d'ale mele andom_quote) [function.main]: failed to open stream: Invalid argument in C:\Documents and Settings\VLADUT ON LICEENI\My Documents\_debug_tmp.php on line 3

 I have solved my problem.
here is a file called random_quote.php:
HTML>
<BODY>
<? //week 4 basic:
$pictures=array("D:\week4\poza_1.jpg","D:\week4\poza_2.jpg","D:\week4\poza_3.jpg","D:\week4\poza_4.jpg","D:\week4\poza_5.jpg");
mt_srand(time());
$random_index=mt_rand(1,count($pictures)-1);
print("<img src=\"$pictures[$random_index]\">");
?>
</BODY>
</HTML>

This is the file that uses random_quote:
<?include("random_quote.php")
?>
My mistake was that I put the adress of the file in the require function,and did not put the file in the root directory.
After i had put the name of the file in the require function and the file In the root directory,the program worked.
PS:I used some photos instead of banners

 on my last post i forgot to say what the problem was. the images did not rotate. it stayed on the first one. however, when i type in 0,4 then it rotates fine, so i think its something wrong with the count function...but it looks good to me..soo, i don't know.

oh and even weirder, when i type both the (0,4) script and this script at the same time, it gives me side by side images, and they rotate exactly the same. im wondering how this is dependent on the other script with (0,4). any ideas?


<?php //ASSIGNMENT 4 BASIC
mt_srand(time());
$random_index=(mt_rand(1,(count($banners)))-1);
$banners=array('banner0.jpg','banner1.jpg','banner2.jpg','banner3.jpg','banner4.jpg');
print("<img src=\"$banners[$random_index]\">");
?>

 To see what you are talking about, try adding a loop to check the randomizations webgourdarzi like this and notice what numbers you see:



$count = count($picture);
for($i=0;$i<100;$i++){
$random_array = mt_rand(0,$count);
print "$random_array, ";
}



$count = count($picture)-1;
for($i=0;$i<100;$i++){
$random_array = mt_rand(0,$count);
print "$random_array, ";
}



Compare the results.
