Returns an associative array that corresponds to the fetched row or FALSE if there are no

|
more rows.

<para>
|
|
The <function>mysqli_fetch_assoc</function> function is used to return an associative array
|
|
representing the next row in the result set for the result represented by the
|
|
<parameter>result</parameter> parameter, where each key in the array represents the name
|
|
of one of the result set's columns.
|
|
</para>
|
|
<para>
|
|
If two or more columns in the result set have the same column name, the associative array
|
|
returned by the <function>mysqli_fetch_assoc</function> function will contain the value of
|
|
the last column of that name. If you must work with result sets with this properity, the
|
|
<function>mysqli_fetch_row</function> should be used which returns an numerically-indexed
|
|
array instead.
