mysql_list_fields ( string database_name, string table_name [, resource link_identifier] )
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.
mysql_list_fields() retrieves information about the given table name. Arguments are the database and the table name. A result pointer is returned which can be used with
mysql_field_flags(), mysql_field_len(), mysql_field_name(), and mysql_field_type().
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 would produce output 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] =>
)

For downward compatibility mysql_listfields() can also be used. This is deprecated however.
See also mysql_field_flags() and mysql_info().
