Dynamic variable name array with an id by PHP

Question

I've to do a variable array with variable name based on ID set by PHP echo.

    <script>
  var dat<?php echo $id; ?>;
  dat<?php echo $id; ?> = ["ecc..","ecc.."];
  </script>

jQuery("#name").html(dat[0]+id); // doesn't work

id is already set by a function, the question is: can i write the VAR correctly including also the PHP ID? Thanks.

Thanks

What does this have to do with Java programming? I don't see any Java in the code above. — Hovercraft Full Of Eels, Sep 04 '16 at 20:47
OK, I've changed your [tag:java] tag to a [tag:javascript] tag. Please understand that these are two completely different programming languages, about as closely related as ham is to hamburger, that if you mis-tag your question you will not get the right experts in to review it, and that this may hurt your chances of getting decent help. — Hovercraft Full Of Eels, Sep 04 '16 at 20:50

Try:

<script>
var dat<?php echo $id; ?>;
dat<?php echo $id; ?> = ["ecc..","ecc.."];

console.log(dat<?php echo $id; ?>[1]);
jQuery("#name").html(dat<?php echo $id; ?>[0]);
</script>

The reason it wasnt working is because dat is dat# where # is an id.

You must access an array element on dat#, not dat[pos]#.
