List MySQL table fields


mysql_list_fields

(PHP 4, PHP 5)

mysql_list_fieldsList MySQL table fields

Description

resource mysql_list_fields ( string $database_name , string $table_name [, resource $link_identifier = NULL ] )

Retrieves information about the given table name.

This function is deprecated. It is preferable to use mysql_query() to issue an 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 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()
