Question

I have this code that executes a for loop in javascript with a php array inside of it. Is there anyway I can use the variable for the loop inside of the php variable for example. This is all inside of php.

echo '<script>
for (var i =0; i<4;i++){

alert("hey"'.$phparr[i].');



}</script>';

I know this will not work because the $phparr is a php variable while the i is a javascript variable is there anyway I can do this?

Answer 1

Try:

<script>    
    var phparr = <?php echo json_encode($phparr); ?>;

    for (i in phparr){

        alert("hey" + phparr[i]);

    }
</script>

PHP is a server side language which means it executes before it reaches the client (browser).

JavaScript is a client side language which means it is executed in the browser (client side).
