Description
int mysql_list_fields
(string database_name, string table_name [, int link_identifier])
mysql_list_fields() retrieves information about the given tablename. Arguments are the database name 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().
A result identifier is a positive integer. The function returns -1 if a error occurs. A string describing the error will be placed in $phperrmsg, and unless the function was called as @mysql() then this error string will also be printed out.
Example 1. mysql_list_fields() example
$link = mysql_connect('localhost', 'myname', 'secret'); $fields = mysql_list_fields("database1", "table1", $link); $columns = mysql_num_fields($fields); for ($i = 0; $i < $columns; $i++) { echo mysql_field_name($fields, $i) . "\n";; } |

The above example would produce the following output:
For downward compatibility mysql_listfields() can also be used.
