I am developing an application having more than thousands of values. I am trying to make a dynamic array in JavaScript. I'm using AJAX to get my values. So I have to create a string from PHP ,it should able to convert from string to array in JavaScript.

How can I make a string in PHP that can be converted to array in JavaScript?

  • you should make json string in PHP and then json to JS object for javascript logic. json.org/js.html Commented Mar 12, 2012 at 10:30

    This isn't hard to do (json_encode is your friend), but "more than thousands of values" suggests you might want to rethink your application architecture... Commented Mar 12, 2012 at 10:30

You are looking for JSON and json_encode():

$string = json_encode($array);

The content of the string will be the array written in valid javascript.

Thanks for instant comment. Actually i want to know how i can make this string from PHP if values generate by a loop. ?
Fas K K Fasil: json_encode accepts an array, so you need to create an array in PHP first, like $array = array(1, 2, 3). Can't give you exact code, because I don't know how your application works.

Use JSON notation to create a string of values and then read it from JS. The simplest way to do this is something like that:

<script type="text/javascript">
var myPHPData = <?php echo json_encode($myData); ?>;
alert myPHPData; // now you have access to it in JS
</script>

json_encode is not useful if string generated by ajax. There i used spli();

if you dont intend to use json , you can do something of this kind..

you can create a string of this kind in php (separate it by any delimiter)

 $arr = "1;2;3;4;5;6;7" ;

in javascript you can convert this to array using split function

 //make an ajax call and get this string (say str)
 arr = str.split(";");

split() returns an array 

 arr[0] is 1 
 arr[1] is 2
 and so on !!
