urgent help needed: passing php variables to javascript

[eon]

I'm trying to loop through a php array in javascript to run them into a function but the $counter variable does not want to get incremented no matter what I do.

**inside of javascript
	var jsize = <? echo $size; ?>;	
	for(var i = 0; i < jsize; i++)
	{
	  var y = <? echo $la[$counter]; ?>;
	  var x = <? echo $lo[$counter]; ?>;
	  var latlng = new GLatLng(y, x);
	  <? $counter = $counter + 1; ?>
          map.addOverlay(createMarker(latlng, i));
	}
**/end of javascript

So you want your JS to increment a PHP variable? Dear God, please tell me you're joking.

well its incremented in php
if you know a better way (already tried like 5 different methods) please let me know

why not just use the value of $i instead of $counter?

also, stick an alert inside the for loop to make sure you actually landing in there

Sure man, I'm going to read your mind and figure out what you want to do. Give me a second... No wait, I forgot I lost my telepathic abilities last week.

You are not able to modify a PHP variable using Javascript. Unless the java script is part of a larger PHP script:

for($counter=0;$counter < $some_value; $counter++)
{

**inside of javascript
var jsize = <? echo $size; ?>;
for(var i = 0; i < jsize; i++)
{
var y = <? echo $la[$counter]; ?>;
var x = <? echo $lo[$counter]; ?>;
var latlng = new GLatLng(y, x);
<? $counter = $counter + 1; ?>
map.addOverlay(createMarker(latlng, i));
}
**/end of javascript

}

Or you make AJAX calls to update a $_SESSION variable.

Though, I am not sure what you want to do. Could you give some more detail?

You realized that as well. Kudos to you.
