Returns an associative array that corresponds to the fetched row,
|
|
or &false; if there are no more rows.</para>
|
|
<para>
|
|
<function>mysql_fetch_assoc</function> is equivalent to calling
|
|
<function>mysql_fetch_array</function> with MYSQL_ASSOC for the
|
|
optional second parameter. It only returns an associative array.
|
|
This is the way <function>mysql_fetch_array</function> originally
|
|
worked. If you need the numeric indices as well as the
|
|
associative, use <function>mysql_fetch_array</function>.
|
|
</para>
|
|
<para>
|
|
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
|
|
<function>mysql_fetch_row</function> or add alias names.
|
|
See the example at the <function>mysql_fetch_array</function>
|
|
description about aliases.
|
|
</para>

<para>
|
|
An important thing to note is that using
|
|
<function>mysql_fetch_assoc</function> is <emphasis>not
|
|
significantly</emphasis> slower than using
|
|
<function>mysql_fetch_row</function>, while it
|
|
provides a significant added value.
