I am attempting to load an array based upon the range of numbers 60 through
69.
The array will have 40 items.
This code produces 9 items just fine.
The rest of the array is empty.
What am I missing?

This:
$ayr[$x]=$yr[$x];
isn't gonna work once $x gets above 9, now is it? Your array $yr only
contains 10 items.

This line:
$ayr[$x]=$yr[$x];
What is the "value" of $yr[$x] when x is greater than 9?

This may be helpful -- specifically the % operator.

You're missing a richardian fuck up in the array indexing!
You also seem to be ignoring a message something like:
"PHP Notice: Undefined offset: 38 in /richardian_array_fuckup.php on
line 13"
Try:
$x=1;
while ($x<40){
$yr=range(60,69);
shuffle($yr);
$n = count($yr);
echo "\$x is {$x}, size of \$yr is {$n} elements, \$yr[\$x] is '{$yr
[$x]}'<br>\n";
$ayr[$x]=$yr[$x];
echo $ayr[$x]."<br>\n";
$x++;
}
and see if that helps you work it out.
By the way, the following code might be useful:
$a=40;
$b=array();
$c=range(60,69);
while(--$a)$b[$a]=$c[array_rand($c)];
assuming that what you actually want is an array of 39 elements indexed
1..39 with random values from 60 to 69.
I doubt that's exactly what you do want, but that's my best guess at what
your code is intended to create.

$x=1;
while ($x<40){
$yr=rand(1,10);
$yr=$yr+59;
$num=rand(1,100);
if ($num<100){$num="0".$num;}
if ($num<10){$num="0".$num;}
$song[$x]="http://mroldies.net/audio/19$yr/".$yr."-".$num.".mp3";
$x++;
}
At this point though, I don't have it worked out to check for duplicats.

What is the point if this second "if"? You've already covered that with

That serves to add padding to three characters. The last three lines
could be replaced with the following:
str_pad(rand(1, 100), 3, '0', STR_PAD_LEFT);

$num = str_pad(rand(1, 100), 3, '0', STR_PAD_LEFT);
as str_pad() does not modify strings (because they are immutable).
Or simply
$num = sprintf('%03d', rand(1, 100));
:)

I do it this way because I've been doing the same method in BASIC for
years. It works fine.
It also helps for sorting purposes.
by having all the strings the same length helps to guarantee that sorting
will not screw it up.
When the number equals 1,
the first "if" adds a zero.
The second "if" adds another zero because it is less than 10.
numbers between 10 and 100 only get one zero added.

No, he hasn't. The point is to pad $num on the left with zeros to a consistent length of 3
characters. Values less than 100 are padded with a zero; values less than 10 are padded
again -- so anything between 1 and 9 inclusive gets two padding characters, and values
from 10 to 99 get only one.

I think what he means to do is:
$x=40;
$song=array();
while(--$x)$song[$x]=sprintf("http://mroldies.net/audio/19%2d/%2d-%
03d.mp3",$yr=rand(60,69),$yr,rand(1,100));

Why not this instead?
$yr = rand(60, 69);

Why would you shuffle a single item?

[4] => 64
[5] => 65
[6] => 66
[7] => 67
[8] => 68
[9] => 69
)
)
... after Shuffle:
php > shuffle(&$ayr[1]);
php > print_r($ayr[1]);

Sorry, I was in a hurry and wasn't paying as much attention.
But then why have 40 different arrays of 10 items each, anyway?
