mysql_list_fields

List MySQL table fields (PHP 4, PHP 5, PECL mysql:1.0)
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 warning 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 1449. 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 downward compatibility, the following deprecated alias may be used: mysql_listfields()
