mysql_fetch_assoc — Fetch a result row as an associative array


array mysql_fetch_assoc ( resource $result )

Returns an associative array that corresponds to the fetched row and moves the internal data pointer ahead. mysql_fetch_assoc() is equivalent to calling mysql_fetch_array() with MYSQL_ASSOC for the optional second parameter. It only returns an associative array.



The result resource that is being evaluated. This result comes from a call to mysql_query().

Return Values

Returns an associative array of strings that corresponds to the fetched row, or FALSE if there are no more rows.

If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you either need to access the result with numeric indices by using mysql_fetch_row() or add alias names. See the example at the mysql_fetch_array() description about aliases.


Example#1 An expanded mysql_fetch_assoc() example



if (!
$conn) {
"Unable to connect to DB: " mysql_error();
if (!
mysql_select_db("mydbname")) {
"Unable to select mydbname: " mysql_error();

$sql "SELECT id as userid, fullname, userstatus 
        FROM   sometable
        WHERE  userstatus = 1"

$result mysql_query($sql);

if (!
$result) {
"Could not successfully run query ($sql) from DB: " mysql_error();

if (
mysql_num_rows($result) == 0) {
"No rows found, nothing to print so am exiting";

// While a row of data exists, put that row in $row as an associative array
// Note: If you're expecting just one row, no need to use a loop
// Note: If you put extract($row); inside the following loop, you'll
//       then create $userid, $fullname, and $userstatus
while ($row mysql_fetch_assoc($result)) {




Note: Performance An important thing to note is that using mysql_fetch_assoc() is not significantly slower than using mysql_fetch_row(), while it provides a significant added value.

Note: Field names returned by this function are case-sensitive.

Note: This function sets NULL fields to PHP NULL value.
