#8569 — returning values from a 2d array

I have been searching the web for an answer but can't really find what I
want to know.

How do I retrieve the values from an array once the random number has been
generated?
In BASIC, one would simply say: show$=top$(1960,1).
In PHP though, it seems you have to go through a miriad of loops just to
find out if the value exists.

So how is this done properly?


<?php 

anum=rand(1,40);   
$num=anum
$number="0" . $num;
if ($num<10) {$number="0" . $number;}
if (Snum>=100) {$number=$num;}

$top[1960][0]= array("top 100 1960");
$top[1960][1]= array("Theme From A Summer Place "," Go-Go-Po-Go "," Percy
Faith "," Columbia 41490 "," Composer: Max Steiner"," Arranger: ","
Producer: "," Composer: Percy Faith "," Arranger: "," Producer: ");
$top[1960][2]= array("He'll Have To Go "," In A Mansion Stands My Love ","
Jim Reeves "," RCA Victor 7643 "," Composer: J. Allison, A. Allison ","
Arranger: "," Producer: Chet Atkins "," Composer: Johnny Russell ","
Arranger: "," Producer: Chet Atkins ");
$top[1960][3]= array("Cathy's Clown "," Always It's You "," Everly Brothers
"," Warner Bros. 5151 "," Composer: Don Everly, Phil Everly "," Arranger:
"," Producer: "," Composer: B. Bryant, F. Bryant "," Arranger: ","
Producer: ");
$top[1960][4]= array("Running Bear "," My Heart Knows "," Johnny Preston
"," Merucry 71474 "," Composer: J. P. Richardson "," Arranger: ","
Producer: "," Composer: J. P. Richardson, J. Preston "," Arranger: ","
Producer: ");
$top[1960][5]= array("Teen Angel "," Bye Now Baby "," Mark Dinning "," MGM
12845 "," Composer: J. Surrey, R. Surrey "," Arranger: "," Producer: ","
Composer: Bryant "," Arranger: "," Producer: ");

$top is a three dimensional array and would be indexed as
$top[$x][$y][$z].  For instance, "Theme From a Summer Place" would be 
$top[1960][1][0] and "Composer: J. P. Richardson" would be
$top[1960][4][4].

I think you're going about this the wrong way, but hey - it's your code.

Not according to the PHP manual.
I have seen the format I'm using online and have tested it.
I tried using $a=$top[1960][anum] and the output was "Array".

What is anum supposed to be? It is not an index. Turn on all error reporting options.

/Str.

Listen to what people are telling you, or stop asking. Of course $top[1960][$anum] is
an array, you assigned it yourself:

$top[1960][2]= array("He'll H....

You have 3 index levels.

Your code does not match what's in the manual.  That's why you get 
"Array" as the output.

What are you trying to do? Pick one song randomly?

Then look at your array:

echo $top[1960][1][0] would give "Theme From A Summer Place"

Just put rand(0,9) as index of the third level, and the rest ... don't know what you
want.

And it is quite near to PHP array abuse, there must be a better representation.

the randomizing feature works quite well.
www.mroldies.net/playertest.php
which randomly selects one of 40 songs each time the page is reloaded.

what I am wanting to do is, print the information for the song below the
player.

Check your typing for '$' designating variables. This is
also important when writing BASIC code.    anum  -> $anum

Check your typing for semi-colons. This is
also important when writing BASIC code.    $num=anum  -> $num=$anum;

Check 'type'-ing to see that you are not asking to concatenate numeric
variables onto character strings. Leading zero suppression is leading
zero suppression, regardless how many zeroes you put in front.
