Returns an array that corresponds to the fetched row or <strong><code>NULL</code></strong> if there are no more rows for the
resultset represented by the <em><code class="parameter">result</code></em> parameter.
</p>
<p class="para">
<span class="function"><strong>maxdb_fetch_array()</strong></span> is an extended version of the
<span class="function"><a href="function.maxdb-fetch-row.html" class="function">maxdb_fetch_row()</a></span> function. In addition to storing the data in the
numeric indices of the result array, the <span class="function"><strong>maxdb_fetch_array()</strong></span> function can
also store the data in associative indices, using the field names of the result set as keys.
</p>
<blockquote class="note"><p><strong class="note">Note</strong>: <span class="simpara">Field names returned by this function
are <em class="emphasis">case-sensitive</em>.</span></p></blockquote>
<blockquote class="note"><p><strong class="note">Note</strong>: <span class="simpara">This function sets NULL fields to
the PHP <strong><code>NULL</code></strong> value.</span></p></blockquote>
<p class="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.
</p>
<p class="para">
The optional second argument <em><code class="parameter">resulttype</code></em> 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 MAXDB_ASSOC, MAXDB_ASSOC_UPPER, MAXDB_ASSOC_LOWER, MAXDB_NUM, or MAXDB_BOTH.
By default the
<span class="function"><strong>maxdb_fetch_array()</strong></span> function will assume MAXDB_BOTH, which is a combination of
MAXDB_NUM and MAXDB_ASSOC for this parameter.
</p>
<p class="para">
By using the MAXDB_ASSOC constant this function will behave identically to the
<span class="function"><a href="function.maxdb-fetch-assoc.html" class="function">maxdb_fetch_assoc()</a></span>, while MAXDB_NUM will behave identically to the
<span class="function"><a href="function.maxdb-fetch-row.html" class="function">maxdb_fetch_row()</a></span> function. The final option MAXDB_BOTH will create a single
array with the attributes of both.
</p>
<p class="para">
By using the MAXDB_ASSOC_UPPER constant, the behaviour of this function is identical to the use
of MAXDB_ASSOC except the array index of a column is the fieldname in upper case.
</p>
<p class="para">
By using the MAXDB_ASSOC_LOWER constant, the behaviour of this function is identical to the use
of MAXDB_ASSOC except the array index of a column is the fieldname in lower case.
