I am running SQL queries in php, and can return the data in JSON format by a pre-built function in the newer releases of php. What I need to do is do the actual JSON encoding in perl. This is what the php code echos, and was hoping to get the result with the JSON module.

{"myData":[{"id":"08-10-2007.00","col2":"2007-08-10","col3":"I","col4"
+:"0","col5":"3951","col6":"8028","col7":"0","col8":"2007-08-10 00:59:
+58"},{"id":"08-10-2007.00","col2":"2007-08-10","col3":"S","col4":"1",
+"col5":"10","col6":"19","col7":"1430","col8":"2007-08-10 00:48:41"}]}

How would I do this in perl using that JSON module? After getting the 8 column results, from the DBI query. How would I loop thru the output so it returns the correctly formatted response like above (can be anywhere from 500 to 100,000 rows)? I just can't seem to figure out how to do it even though it's probably super easy. Here's the simple while loop that grabs each row. How would I push all these variables into an array/hash and encode it to JSON to give the correct response to the browser?

        $sth->execute();
        while (($col_val1,$col_val2,$col_val3,$cdr_day,$call_status,$i
+sdn_code,$cdr_count,$hold_time,$duration,$lastcall)
                = $sth->fetchrow_array)
        {

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
