Ajax调用PHP

Question

I'm working in a project which I have to use several inputs which have to be completed by the client inserting a number. If the number is equal or more than 6, 'aprobada' should appear in the input text, else 'reprobada'. Is it possible to pass variables from php to jquery?

All comments and feedback are welcome :)

Thank you!

CODE JQUERY ,HTML


<script src="jquery-2.1.0.js" type="text/javascript"></script>   
<script>
function submitForm() {
$.ajax({type:'POST', url: 'formtronco.php', data:$('#troncocomun').serialize(),
success:    function(response) {


$('#troncocomun').find('#aqui').html(response);  /*here would be this variable  
'$acreditacion[0]' from php to respond in '#aqui'*/   
$('#troncocomun').find('#alla').html(response); /*here would be this variable    
'$acreditacion[1]' from php to respond in '#alla'*/ 
}});


return false;
}

</script>

CODE PHP:

$acreditacion=array($_POST['1'],$_POST['2']);
if ($acreditacion[0] >=6 ) {
echo "Aprobada";}
else{
echo "Reprobada";
}

if ($acreditacion[1] >=6 ) {
echo "Aprobada";}
else{
echo "Reprobada";
}


} 
?>

Not the tidiest thing, really. But this answer your question:

<script>
var someVariable = <?php echo $phpVar; ?>;
</script>

Assuming $phpVar = 1, this'd output:

<script>
var someVariable = 1;
</script>

Make sure you include this BEFORE other javascript that references this variable.

You shouldn't be doing this though, since it's very untidy - you should't actually be needing to "pass variables" like that.
