how to pass javascript variable into php session

Hello Experts,

I can not pass javascript variable into php session.
My code:

function keepID(myform)
{
i = 0, inputs = document.myform.getElementsByTagName('input');
for(i=0;i<<?php echo $_SESSION['row'] ?>;i++)
{
if(document.myform.chkID.checked==true)
{
x=document.myform.chkID.value;

}

}
}
My checkboxes are moving in a loop:
<input type="checkbox" name="chkID[]" id="chkID" value="<?=$rowSubjects['ID']?>" onClick="return keepID(this);">
Please help...

 

Can you click "View Souce" in web browser and look the JavaScript code that was generated after <?php echo $_SESSION['row'] ?> was done ? Does this php code was runned and any integer was passed into javascript code ?

 

I have clicked "View Souce" in web browser and look the JavaScript code that was generated after <?php echo $_SESSION['row'] ?>.This php code was runned and integer was passed into javascript code .
Php variables are passing to javascript but dont know how to do vice versa.

Thanks for your interest in it. Waiting for reply.
Thank you.

 

So, if php expression was successfully replaced by integer - which problem do you have ?

 

Thanks for the reply.

function keepID(myform)

for(i=0;i<<?php echo $_SESSION['row'] ?>;i++)
{
if(document.myform.chkID.checked==true)
{
x=document.myform.chkID.value;
<?php $_SESSION['checkboxID'][$i] ?>=x;//My this line is not working
}

}
}
Please help..
