LEARN ABOUT PHP
mysql_list_fields
MYSQL_LIST_FIELDS(3) 1 MYSQL_LIST_FIELDS(3)
mysql_list_fields - List MySQL table fields
SYNOPSIS
Warning
This function was deprecated in PHP 5.4.0, and will be removed in the future, along with the entirety of the original MySQL exten-
sion. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more
information. Alternatives to this function include:
oSQL Query:
SHOW COLUMNS FROM sometable
resource mysql_list_fields (string $database_name, string $table_name, [resource $link_identifier = NULL])
DESCRIPTION
Retrieves information about the given table name.
This function is deprecated. It is preferable to use mysql_query(3) to issue an SQL SHOW COLUMNS FROM table [LIKE 'name'] statement
instead.
o $database_name
- The name of the database that's being queried.
o $table_name
- The name of the table that's being queried.
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
A result pointer resource on success, or FALSE on failure.
The returned result can be used with mysql_field_flags(3), mysql_field_len(3), mysql_field_name(3) and mysql_field_type(3).
Example #1
Alternate to deprecated mysql_list_fields(3)
<?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] =>
)
Note
For backward compatibility, the following deprecated alias may be used: mysql_listfields(3)
mysql_field_flags(3), mysql_info(3).
