Php pass array to Javascript

Question

I want an array in Javascript, structure like this

 $(function()
 {
 // prepare the data
 for (var i=0; i<50000; i++) {
 var d = (data[i] = {});
 d["id"] = "id_" + i;
 d["num"] = i;
 d["title"] = "Task " + i;
 d["duration"] = "5 days";
 }

I want this array to be created through php. I already have the array there created by for loop

EDITED:

Is the above data in Javascript a multidimensional array, a simple array or a var?

is the structure saved in "d" or in data[i][id],data[i][title],... ?

• Jonah: And please mark the best answer to your question here.
• Email: sorry now i will. i did not know so far, thx 4the hint

Answer 1

ie, $data = array('item' => 'description', 'item2' => 'description2');

json_encode($data);

All you need

• user229044: Dumping an array of 50,000 elements onto the page is hardly ideal, but without more info I don't see a better solution.
• Jonah: I don't think putting 50,000 of anything onto one page using any method is ideal.

Answer 2

Use json_encode() to encode the array.

Access PHP variable in JavaScript That example works with arrays, too.

• rhino: Sorry, I don't get you. What do you mean by saying "it's quicker"?
• Jonah: Linking to your answer, instead of writing it again. :) </offtopic>
• Email: could you give an example in php how the structure of the array has to look to fit into the Javascript. The javascript part as i understood your answer is simply echoing var d=<?php echo json_encode($data); ?>
• Jonah: Any array, string, or integer can be passed through. Json_encode takes care of the rest.
