[[SOLVED] how to add a randomizer]

hi all,

 

I am working on a project that must use only php (no database unfortunatly).

It has to generate a selected number of random quotes but they must not repeat themselves.

 

the quotes I have put into an array like so:

 

<ul>
     1.<?php
	echo ($quote[0]);
	?>
</ul>
<hr />
<ul>
	2.<?php
		echo ($quote[1]);
	?>
        </ul>
<hr />
<ul>
        3.<?php
	echo ($quote[2]);
	?>
</ul>
<hr />
<ul>
	4.<?php
	echo ($quote[3]);
	?>
</ul>
<hr />
and so on

 

I know i need need to replace the numbers within the  [] with a random number and I have a way to generate random numbers that do not repeat. Like so.

 

<?php
function rand_group($num) {
   $ary = range(1,50);
   shuffle($ary);
   return array_slice($ary, 0, $num);
}

echo implode(', ',rand_group(5));
?>

 

I just dont understand how i can get the numbers generated from this code into the [] to make sure i get no repeating quotes.

 

I'm still very new at php but sometimes seems like i'm getting there just for hiccups like this to stump me totally.

 

Any help would be greatly appreciated.

 

Thanks

[[SOLVED] Random numbers within a certain range that do not repeat.]

Hi I am a bit new to php and have run into a problem, I need to generate a random number list on request from a user.

 

eg, user selects 20 so I would need to have 20 unique random numbers from a range of 1-500.

 

I tried to work things out and eventually after much trial and error, searching and deleting I found this here which is using random range and shuffle.

Unfortunately this gives me 500 unique random numbers instead of 20 as I had hoped.

 

<?php
function rand_group() {
   $ary = range(1,500);
   shuffle($ary);
   return($ary);
}

echo implode(', ',rand_group(20));
?>

 

Any help would be great, this seems so close to what I need so I am thinking I am missing something really simple.

[Center vertically and horizontally]

if its just an image and you want centered and you are going to be declaring the height you could make the image into a background and then use the following css.

 

background: url(image_name.jpg) center no-repeat #color;

 

Hope this helps

[[SOLVED] replacing special characters]

thanks a ton I followed the link you gave and found a better way to get the job done than I had thought of.

 

I was thinking I would have to do a lot of if else type coding for each character that wasn't displaying properly, on the link you gave me I found:

 

// Provides: You should eat pizza, beer, and ice cream every day
$phrase  = "You should eat fruits, vegetables, and fiber every day.";
$healthy = array("fruits", "vegetables", "fiber");
$yummy   = array("pizza", "beer", "ice cream");

$newphrase = str_replace($healthy, $yummy, $phrase);

 

which with a small amount of editing has saved me a ton of coding.

 

now I just have to find out how to mark this thread as solved:)

 

Thanks again

[[SOLVED] replacing special characters]

hi I kind of know what I need to achieve here just not sure how to accomplish it. Basically I have a text box and when users type into it it doesnt seem to understand characters like pound signs and things, so to fix this problem i am thinking some code that basically does something like:

 

If £ found

replace £ with £

 

and then repeat that for several character types but im just not sure how to go about it.

 

Any help would be greatly appreciated, thanks.

[Perfect quiz not working]

hello all,

 

I will start by saying I am a php newb, been book learning a little while but struggling. I have been asked by my work to produce a kind of training website so I decided since I had started learning php I would use it. After a few attempts and not being able to get my head around certain problems I went looking for a 3rd party program, after much searching I found a linkware script that does everything I need for my project, used their demo and it was great (I got it from http://www.multiwebvista.com/testzone/download.php), so I downloaded it but cant seem to add questions to the mysql database using the admin that it comes with.I did manage to add subjects but couldnt add questions but to get that far I had altered a lot of the code and I am really not sure what I was doing so have reverted back to the original code to start again. I know any kind of walkthrough on getting this working is a is a massive ask but I am getting desperate, I tried emailing the original maker but it appears the contact details on his site are no longer valid.

 

Any help you guys can give me would be much appreciated.

 

Thanks
