php associative array to JS?

[ginerjm]

After much research and some great tips, I have managed to move a php generated query/array to a js array.  My code works great and all but what I need to do now is to make the js array an "associated" one.

 

Ex.

my php query produces a result of

1 Tiger

4 Phil

3 Nick

 

I can make an assoc array in php that would look like:

$ar["1"] = "Tiger"

$ar["4"] = "Phil"

 

instead of

$ar[0] = "Tiger"

$ar[1] = "Phil"

 

How can I get the assoc php array format into a js array so that I can do a look up on a value of "4" and come up with "Phil" instead of undefined?  Does JS even have associative arrays?

When you generate $ar, give a key. For example,

$ar[$row["id"]] = $row["name"];

Then use json_encode.

 

JavaScript has objects, which can be treated as associative arrays. So yes, it does.

ok - I have an assoc php array that works just like I want it to.  The indices of it are not 0.....n but instead the assigned numbers I have in my sql table.

 

I use this to build my js array

var jsgolfers = ["<?php echo implode("\",\"",$golfers); ?>"];

 

which builds just a normal enumerated array, even tho the indices of $golfers are not enumerated.

 

So - while php tells me that $ar["4"] (which is actually the 2nd element) is "Tiger", JS says it is a couple more cells down the line and shows "Phil".

 

Any way of managing this in JS?

Use json_encode() instead of your own creation.

var jsgolfers = ;

you da man!  That was the simplest fix I've ever been given in all my years on many different forums for many different subjects.

 

Thank you very much.
