Example 1. mysql_list_fields() example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$fields = mysql_list_fields("database1", "table1", $link);

for ($i = 0; $i < $columns; $i++) {
echo mysql_field_name($fields, $i) . "\n";

For downward compatibility mysql_listfields()
can also be used. This is deprecated however.
Note:
The function mysql_list_fields() is deprecated. It
is preferable to use mysql_query() to issue a
SQL SHOW COLUMNS FROM table [LIKE 'name'] Statement instead.
