fbsql_field_name

Get the name of the specified field in a result (PHP 4 >= 4.0.6, PHP 5)
string fbsql_field_name ( resource result [, int field_index] )

说明

fbsql_field_name() returns the name of the specified field index. result must be a valid result identifier and field_index is the numerical offset of the field.

注意:

field_index starts at 0.

e.g. The index of the third field would actually be 2, the index of the fourth field would be 3 and so on.
