XXII. dBase Functions

Введение

These functions allow you to access records stored in dBase-format (dbf) databases.

dBase files are simple sequential files of fixed length records. Records are appended to the end of the file and delete records are kept until you call dbase_pack().

The types of dBase fields available are:

Таблица 1. Available types of fields
FielddBase TypeFormatAdditional informations
MMemon/aThis type is not supported by PHP, such field will be ignored
DDateYYYYMMDDThe field length is limited to 8
NNumberA number You must declare a length and a precision (the number of digits after the decimal point)
CStringA stringYou must declare a length. When retrieving data, the string will be right-padded with spaces to fit the declared length.
LBooleanT or Y for TRUE, F or N for FALSEStored and returned as an integer (1 or 0)

Внимание
There is no support for indexes or memo fields. There is no support for locking, too. Two concurrent webserver processes modifying the same dBase file will very likely ruin your database.

We recommend that you do not use dBase files as your production database. Choose any real SQL server instead; MySQL or Postgres are common choices with PHP. dBase support is here to allow you to import and export data to and from your web database, because the file format is commonly understood by Windows spreadsheets and organizers.

Установка

In order to enable the bundled dbase library and to use these functions, you must compile PHP with the --enable-dbase option.
