Random pieces of text from an array

Anon

Hi,

I've got a problem with displaying a random piece of text. The construction of my webpage is as follows: In main.php a file called jokes_page.dat is included. jokes_page.dat looks like this:

<?php

//put the jokes into an array
$joke_array = explode ("##########", jokes.dat);

//randomize the array
shuffle ($joke_array);

$title = "Jokes Page";
$content = "Random Joke: $joke_array";

jokes.dat contains the jokes, devided by ##########. In the main page I then echo $title and $content. The problem I'm encountering is that instead of the random joke the word 'Array' is displayed ... I have no idea why this happens. Any suggestions?

Thanx Michiel

$content = "Random joke: $joke_array";

How about

$content="Randome joke: $joke_array[0]";

Array elements have to be referenced using an indice...

You can fetch value of an element of the array by using the index. You are trying to use the array directly. The result is going to be "Array"

Solution:
<?php

//put the jokes into an array
$joke_array = explode ("##########", jokes.dat);

//randomize the array
shuffle ($joke_array);

$title = "Jokes Page";
$content = "Random Joke: $joke_array[$index]"; // $index can be any value between
0-(arraylength-1)

Hi,

thanks for your reaction. But unfortunately I'm stil having some problems. When I give $index the value 0, the outcome is 'jokesdat'. When I give $index a value above 0, nothing is displayed at all. I don't understand it all. Is it possible that it has to do with the fact that jokes_page.dat is included in the mainpage? Or does it have to do with the construction of jokes.dat?

I hope you can help, thanx anyway, Michiel

haha...

Did you open the file???

$fp=fopen("jokes.dat", "r");
$jokes=fread($fp, filesize("jokes.dat"));
fclose($fp);
$jokes=explode("#####", $jokes);
shuffle($jokes);

echo "$jokes[0]";
