Question

if i have a function like that:

function ($form, $db) {  
     $v = count($a);
}

function ($form, $db);

and this code in the same file

<script type="text/javascript">
$(document).ready(function() {
    for ($i=0; $i< <?php echo $v-1; ?>; $i++) {//here
}

how can i access the variable $v ? i already know that global variables are generally a bad practice, so what is the alternative?

thanks

Use return $v:

function ($form, $db) {  
     $v = count($a);
     return $v;
}

<script type="text/javascript">
$(document).ready(function() {
    for ($i=0; $i< <?php echo function( $form , $db )-1; ?>; $i++) {//here
}
