fbsql_list_fields

List FrontBase result fields (PHP 4 >= 4.0.6, PHP 5)
resource fbsql_list_fields ( string database_name, string table_name [, resource link_identifier ] )

说明

fbsql_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 fbsql_field_flags(), fbsql_field_len(), fbsql_field_name(), and fbsql_field_type().

A result identifier is a positive integer. The function returns FALSE if an error occurs. A string describing the error will be placed in $phperrmsg, and unless the function was called as @fbsql() then this error string will also be printed out.

for (
$i = 0; $i < $columns; $i++) {
   echo
fbsql_field_name($fields, $i) . "\n";;
