<function>mysql_list_fields</function> retrieves information
|
|
about the given table name. Arguments are the database and
|
|
the table name. A result pointer is returned which can be used
|
|
with <function>mysql_field_flags</function>,
|
|
<function>mysql_field_len</function>,
|
|
<function>mysql_field_name</function>, and
|
|
<function>mysql_field_type</function>.

<?php

The above example would produce the following output:
|
|
<screen>
|
|
<![CDATA[
|
|
field1
|
|
field2
|
|
field3
|
|
...
|

]]>
|
|
</screen>
|
|
</para>
|
|
</example>
|
|
</para>
|
|
<para>
|
|
For downward compatibility <function>mysql_listfields</function>
|
|
can also be used. This is deprecated however.
|
|
</para>
|
|
<!-- TODO: this is equiv. with 'select * from $table where &false;,'
|
|
which implies you can better use the field-research functions
|
|
on a real query, that saves you one mysql-query.
