Assume I have an array: $elements = array('foo', 'bar', 'tar', 'dar'); Then I want to build up a DELETE IN SQL query: $SQL = "DELETE FROM elements WHERE id IN ('" . implode(',', $elements) .

You don't need to know JavaScript to be able to understand how to use jQuery, but it certainly doesn't hurt and once you begin

I have an array like: Array ( [0] => Array ( [0] => a [1] => b ) [1] => Array ( [0] => c ) [2] => Array ( [0] => d [1] => e [2] => f ) ) I want to convert my array to a string like below: $arrtostr = 'a,b,c,d,e,f'; I've used implode() function but it looks like it doesn't work on two-dimensional arrays.
