Function to separate array created by mysql fetch array

Hi all,

I create an array using the $row = mysql_fetch_array($result,MYSQL_BOTH)function.

It's great because i can reference an element value using either the numeric or associative key. However, I need to pass only the numeric keyed portion of the array as a json string back to the client side.

Is there a PHP function that will separate numeric array from the associative array?

I checked the php site but could not find any so i thought i'd check with you all.

MYSQL_BOTH is actually the default, as if no 2nd argument is passed. Can you not simply pass MYSQL_NUM in order to return an array with only numeric indices, or do you need the column names elsewhere in your script?

I use the associative indices to easily assign values to the elements without having to count or remember which numeric index it is. However, when i construct the json object before encoding it and sending it to the client side, i want to use the numeric key array.

This will do what you want:

while ($row = mysql_fetch_array($result)) {
ksort($row, SORT_STRING); //will order $row so all numeric indices are first
$tmp = array_slice($row, 0, count($row) / 2); //all the numeric indices from $row
//do something with $tmp
