How to work with jQuery AJAX and PHP array return

In your PHP code encode the array as JSON object echo json_encode($array); Then you need to convert the JSON object into a Javascript/jQuery-compatible object. Afterwards you can convert back to an array $.ajax({ success: function(result) { jq_json_obj = $.parseJSON(result); //Convert the JSON object to jQuery-compatible if(typeof jq_json_obj == 'object'){ //Test if variable is a [JSON] object jq_obj = eval (jq_json_obj); //Convert back to an array jq_array = []; for(elem in jq_obj){ jq_array.push(jq_obj[elem]); } console.log(jq_array); }else{ console.log("Error occurred!"); } } });
