List MySQL table fields mysql_list_dbs mysql_list_processes MySQL Functions PHP Manual mysql_list_fields (PHP 4, PHP 5, PECL mysql:1.0)mysql_list_fields — List MySQL table fields Description resource mysql_list_fields ( string $database_name , string $table_name [, resource $link_identifier ] ) Retrieves information about the given table name. This function is deprecated. It is preferable to use mysql_query() to issue a SQL SHOW COLUMNS FROM table [LIKE 'name'] statement instead. Parameters database_name The name of the database that's being queried. table_name The name of the table that's being queried. link_identifier The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level error is generated. Return Values A result pointer resource on success, or FALSE on failure. The returned result can be used with mysql_field_flags(), mysql_field_len(), mysql_field_name() and mysql_field_type(). Examples Example #1 Alternate to deprecated mysql_list_fields() <?php$result = mysql_query("SHOW COLUMNS FROM sometable");if (!$result) { echo 'Could not run query: ' . mysql_error(); exit;}if (mysql_num_rows($result) > 0) { while ($row = mysql_fetch_assoc($result)) { print_r($row); }}?> The above example will output something similar to: Array ( [Field] => id [Type] => int(7) [Null] => [Key] => PRI [Default] => [Extra] => auto_increment ) Array ( [Field] => email [Type] => varchar(100) [Null] => [Key] => [Default] => [Extra] => ) Notes Note: For backward compatibility, the following deprecated alias may be used: mysql_listfields() See Also mysql_field_flags() mysql_info() mysql_list_dbs mysql_list_processes MySQL Functions PHP Manual
