Get data array from PHP to JavaScript

Question

I want to get data array from php to Javascript. (Actually I am doing plotting using javascript library and the data is in the database: I get the data using php script and want to use that data for plotting). I have tried to use a JSON for this. My code looks follows but it is not working. Please give me a help on this

 <script type="text/javascript">

<?php

 $php_arr=array('abc','def'); // I want to transport this array to javascript

  echo "display_diagram(" . json_encode($php_arr) . ")";
?>

    function display_diagram(data) {


       obj = JSON.parse(data); // this is not working for me 

Answer 1

Try use data variable in display_diagram function without JSON.parse. You now give data attribute in json format and this not require additional json parsing.

Check this:

<script>
<?php

 $php_arr=array('abc','def'); // I want to transport this array to javascript

  echo "display_diagram(" . json_encode($php_arr) . ")";
?>

function display_diagram(data){

    obj = data;
    alert(obj);
}
</script>
