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 <b>maxdb_fetch_array()</b> 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 <a href="function.maxdb-fetch-assoc.html" class="function">maxdb_fetch_assoc()</a>, while MAXDB_NUM will behave identically to the <a href="function.maxdb-fetch-row.html" class="function">maxdb_fetch_row()</a> function. The final option MAXDB_BOTH will create a single array with the attributes of both. </p>⌨️ 快捷键说明
