I need to pass a php variable to a jquery function. the php variable is an array of unknown size. is there a way to pass each member of the array to be processed individually by the function?

I Guess you should use JSON to pass the php variable to jquery. its the easiest way to do that.

You can use JSON to print the array and parse that to receive a JS object.
I assume you use AJAX (directly printing into the javascript source is possible but ill-advised).
Your php script needs to print output directly:
print_r(json_encode($data_array));
And on the receiving end use $.parseJSON:
var data_array = $.parseJSON(ajax_result);

echo instead of print_r for passing it to a JS var/Ajax response btw.

@FabrícioMatté There is little difference in this case. print_r does not format the data in any way unless it is an object or an array. Also, you can rig print_r to return the value and use it in expressions, which is impossible for echo.
