Parsing javascript arrays in PHP

Question

I can\'t seem to figure out how to get a JS array into PHP.

What I have to work with looks like this:

var arrLow = [
{
\"e\": \"495864\",
\"rank\": \         


        

Answer 1

2 options:

1. Just remove the var arrLow = at the front (might need a regex if its variable), and parse as json.
2. Go for full on javascript parsing

Answer 2

You can use json_decode() for this. The trick is to leave away the var arrLow = part (so that only the array itself is left). You can assign the value to the php variable $arrLowlike this:

$js = '[ {"e" : "495864", ...';
$arrLow = json_decode($js);

A quick'n'dirty hack to remove the beginning would be to use the strstr() function.

$js = strstr('var arrLow = [ {..', '[');

Answer 3

//define javascript array 
>var mainArray = {};    
>       // inner loops
mainArraySub['XXX'] = [];    

             mainArray = JSON.stringify(mainArray);
      passing javascript array content in jquery ajax request as 
      $.ajax({
       type: "POST",
     data:{paramval:mainArray},
     dataType: "json",
    url: url,
   success: function(msg){

          }
      });    


in POST request you will get as below

{"row1":{"0":{"nnnn":"aaaa"},"1":{"Movie":"aaaa"},...}        

// in a.php file call as below

$Info = $_REQUEST['rowdata'];
$tre = json_decode(stripslashes($Info),true);
var_dump($tre);        

Answer 4

According to the JSONLint validator this is valid JSON (without the var arrLow =). So any good json_decode() implementation should do the trick. Maybe the implementation you are using has certain limitations? The JSON.org website has a neat list of links to implementations of json_decode in PHP (and lots of other languages too). You can be sure to find one that does work.
