<para>
|
|
Returns an array that corresponds to the fetched row or &false; if there are no more rows for the
|
|
database connection represented by the <parameter>link</parameter> parameter.

<para>
|
|
<function>mysqli_fetch_array</function> is an extended version of the
|
|
<function>mysqli_fetch_row</function> function. In addition to storing the data in the
|
|
numeric indices of the result array, the <function>mysqli_fetch_array</function> function can
|
|
also store the data in associative indices, using the field names of the result set as keys.
|
|
</para>
|
|
<para>
|
|
If two or more columns of the result have the same field names, the last column will take
|
|
precedence and overwrite the earlier data. In order to access multiple columns with the same
|
|
name, the numerically indexed version of the row must be used.
|
|
</para>
|
|
<para>
|
|
The optional second argument <parameter>result_type</parameter> is a constant indicating what
|
|
type of array should be produced from the current row data. The possible values for this parameter
|
|
are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH. By default the
|
|
<function>mysqli_fetch_array</function> function will assume MYSQLI_BOTH for this parameter.
|
|
</para>
|
|
<para>
|
|
By using the MYSQLI_ASSOC constant this function will behave identically to the
|
|
<function>mysqli_fetch_assoc</function>, while MYSQLI_NUM will behave identically to the
|
|
<function>mysqli_fetch_row</function> function. The final option MYSQLI_BOTH will create a single
|
|
array with the attributes of both.
