you should consider using JSON strings in order to use key based arrays in JavaScript.

Use json_encode to convert your php array to json :)

A possible solution is to convert php array structures into JSON before passing the data to the client.

Have a look at php json. And also have a look at this post.

Try with Json:

json_encode($array);

This will encode the array into a json object, that is friendly with javascript (and Jquery).

If you are passing it through an ajax request just echo it in the php and return that as response.

If it's in the same script you could do:

$object = json_encode($array);
echo "var myObject = $object;";

And for accessing the information in javascript/jquery you would do:

alert(myObject[0].price_id);

you use myObject[0] to access positions as in php arrays, and myObject[0].name to access what would be associative array key in an array.

For more information visit json documentation page

Well while you ask to move from [php]array to [javascript]array, this is how to. You should ue json_encode how the previous answer said, but in you javascript you can use the following code to convert a json into an array:

function json2Array = function(json){   
    var a = [];
    for(var o in json){
      a.push(json[o]);
    }   
    return a;
}

var myArray = json2Array(youPhpJsonEncode);

and you will have your array in javascript

i am sorry, i still don't know how to do, if this is my jquery code.$('input').on('keyup', function() { var result = 0; $(' li input').each(function() { result += parseInt(this.value, 10); });

i want to make a compare between the result and the [price_qty] value which from the php array.

Ok so what you have to do is how @aleation said in php write $object = json_encode($array); echo "var myObject = $object;"; and insert the code before any javascript code then you can iterate with jQuery Each method $.each(myObject, function(_index, _item){ var objectInArray = _item; if(objectInArray.price_qty == "somevalue"){ //do something } });

i did as your told.$object = json_encode($array); echo "var myObject = $object;";<script> jQuery(document).ready(function () { jQuery.each(myObject, function(_index, _item){ var objectInArray = _item; if(objectInArray.price_qty == 2){ alert('hello'); } }); )} </script> there is no value alert.

before echo the value of the json_encode in you html if this has content then move to the javascript if not something went wrong in php... does this has content?
