Execute php script inside a javascript script -

i've got problem using javascript (as i'm pretty new language)

my problem : i've got javascript script adds form fields when click on button, , change name incrementing it. data stored array. when i've saved filled fields, need them , show them <input type="text" value="<?php $myvalue[] ?>"/>. problem is, need javascript file, , don't know how can interpret stuff inside php script.

here's i've tried :

var counter = 1; var limit = 10; var new_div = '<?php echo json_encode($arrayspecialite['+ counter +']); ?>'; function addinput(divname){ if (counter == limit)  {       alert('you cannot add more than' + counter + ' fields');  }  else {       var newdiv = document.createelement('div');       newdiv.innerhtml = 'specialité ' + (counter + 1) + ' <br><input type="text" name="specialite[]" id="specialite[]"" value="'+ new_div +'">';       document.getelementbyid(divname).appendchild(newdiv);       counter++;  } } 

thank's in advance.

you can differents things:

in php return initial view, return response contains javascript hold data.

eg:

<script>     var new_div = '<?php echo json_encode(array(1,2,3)); ?>' </script> 

so if javascript run in same scope, or in inner scope have access variable.

or

make ajax request , read response server

xmlhttp.onreadystatechange=function() {     if (xmlhttp.readystate==4 && xmlhttp.status==200) {         console.log(xmlhttp.responsetext);     } } xmlhttp.open("post","myscript.php",true); xmlhttp.setrequestheader("content-type","application/x-www-form-urlencoded"); xmlhttp.send("name=shikaka&lastname=ventura"); 

when myscript.php receive request work (make sure escape values) , return response

<?php      echo json_encode(array(1,2,3));
