A guestion about arrays

Anon

I have just started with PHP4, i have 2 books on it that i have read and i have a question. I am still waiting for my hosting account so i cannot test my theory. my question is can i do this echo
$char[$loop];

then if $loop = 4 lets say then that will display $char[4] right, as in what ever is in that array on the fifht place? i might be totally wrong but i have about 2 more days left before my host become active, and i have been writing some News update scrips. thanks for your time

You are correct 🙂

Now, if $char is a string like "stuff" then I think the syntax might be changing to use round braces like

$char="stuff";
$loop=4;
$char($loop);

to distinguish strings from arrays.

If you are really pressed you could install PHP on your local machine (Win or *nix) for testing. There are some great tutorials and howto's to do that for local development.

hey Tim thanks for responding so fast. Now i don't totally understand what $char($loop); will contain if i use your example. let me try to explain a little more. what i am trying to do is load little of up to 50 bytes long into an array so that i can display them in a row. Again i am new and i know that there is probebly an easier way, but i just have not figured it out yet. 🙂

Go to hotscripts.com and search for PHPTriad. You can install that and have a PHP/MySQL/Apache test environment set up on your windows machine in 10 minutes...

If you want to store something in an array then you would do

$myarray[0] = "50 bytes of stuff";
$myarray[1] = "50 more bytes";
etc..

Then you get at it like you wanted to with

$loop=1;
$myarray[$loop];

if you just did

$myarray = "50 bytes of stuff";

then $myarray[$loop]; (same as $myarray($loop) for now)

would get you the second character which would be a 0 rather than the sentence "50 more bytes"

Hope that explains it a bit more

If you want to retrieve data out of an array this is what you can do.

Let's say that your array has values:

$stuff[0]="word1";
$stuff[1]="word2";

etc...

you write a loop

for($i=0; $i<count($stuff); $i++)
{
echo "$stuff[$i]<br>";
}

And it will display all the elements of your array without you needing to know how many elements are in there.
