Using Multidimensional Array

[daveasc]

Ok, new to PHP ... trying to figure out how to use a multidimensional array,the one shown below. The print_r works fine. But how do I use the array to show the values in another page, e.g. on the new page I want to display the "4" from the "Par" array and the "410" from the "BackYardage" array.  Probably very simple but can't figure it out.  Thanks.

 

$teeboxes = array

  (

 

   "Par" => array

       ("4","5","3","4","3","4","4","5","4","4","5","3","4","3","4","4","5","4"),

 

    "BackYardage" => array

       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),

  

    "MiddleYardage" => array

       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),

 

    "FrontYardage" => array

       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),   

  

  

    "ForwardYardage" => array

       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),

 

    "SeniorYardage" => array

       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),

 

  ); 

 

 echo "<p> Dump of Tee Box array <p>";

 print_r($teeboxes);

Like this

$teeboxes = array
  (
   "Par" => array
       ("4","5","3","4","3","4","4","5","4","4","5","3","4","3","4","4","5","4"),
    "BackYardage" => array
       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),
    "MiddleYardage" => array
       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),
    "FrontYardage" => array
       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),    
    "ForwardYardage" => array
       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),
    "SeniorYardage" => array
       ("410","525","173","394","133","410","425","590","410","410","525","173","394","133","410","425","590","410"),
 
  ); 

/*********************************************
* Display the data
**********************************************/
for ($tee=1; $tee<=18; $tee++) {
    echo "<strong>Tee : $tee</strong><ul>";
    foreach ($teeboxes as $desc => $data) {
        echo "$desc : {$data[$tee-1]}<br>";
    }
    echo "</ul><br>"; 
} 

/* RESULTS
Tee : 1

    Par : 4
    BackYardage : 410

But why not just pull it from your database on the page where you want to display the data?

Thanks, Barand.  It does as you say.  But two things:

 

1. Can you explain what is going on?  I am totally new to PHP, at least working with arrays. What is "$desc"? How does echo $desc : {$data[$tee-1]}  work? Or where can I read up of this?

 

2. What I really want is to be able to take the "Par" and one of the teeboxes, e.g. "BackYardage" and put them into variables that I can display on a  page.  Then I could display any of the teeboxes.

 

Hope this make sense to you.  It seems like I should be able to do something like this:

 

$hole1par = the 1st par, $hole2par = 2nd par, etc..

$hole1yardage = the 1st yardage for BackYardage, $hole2yardage = 2nd BackYardage, etc. 

 

I just don't know how to access any part of the array.

 

Thanks )

There is no point in putting the values from the array into 108 separate variable (6x18)

 

When using

 foreach ($array as $key => $value)

it loops through the array putting the key into $key (in this case the description ($desc) such as par, frontyardage etc) and the value into $value. In this case the value is an array of the 18 hole values. The  indexes of these arrays is numeric from 0 to 17 (ie hole - 1). I used $tee for the hole number.

 

So, if you want the par value for the 12th hole it would be in the variable $teeboxes['Par'][11]

The FrontYardage for for 6th hole would be in $teeboxes['FrontYardage'][5]

Thanks once again ... starting to come through little by little ... I had a general idea how it should work but it takes a long time to figure things out by "trial & error" ... mostly error   I am sure I will be back again for further education ...

Is it possible to "include" the array, $teeboxes, in a page on my site and use it just as if it was there all along?  I mean, suppose I have that code in another php file named, "andersonyardages.php".  I would like to be able to use the $teeboxes so I could use the data in the array without actually coding the data in a current file.
