PHP 8.4.0 Alpha 2 available for testing



Esta extensión se ha movido al repositorio de » PECL y ya no se distribuye con PHP a partir de PHP 5.3.0.

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


We recommend against using dBase files as your production database. Use » SQLite or 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.


As of dbase 7.0.0 the databases are automatically locked via flock(). There has been no support for locking earlier, so two concurrent web server processes modifying the same dBase file would have very likely ruined your database. This can happen even with dbase 7.0.0+ on systems which implement the locks at the process level with multithreaded SAPIs.

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

Only dbf file levels 3 (dBASE III+) - 5 (dBASE V) are supported. The types of dBase fields available are:

Available types of fields
Field dBase Type Format Additional information
M Memo n/a This type is not supported by PHP, such field will be ignored
D Date YYYYMMDD The field length is limited to 8
T DateTime YYYYMMDDhhmmss.uuu (FoxPro) No validity checks are done. Available as of dbase 7.0.0.
N Number A number You must declare a length and a precision (the number of digits after the decimal point).
F Float A float number Same as N.
C String A string You must declare a length. When retrieving data, the string will be right-padded with spaces to fit the declared length. Overlong strings will be silently truncated when storing data.
L Boolean T or Y for true, F or N for false, ? for uninitialized. As of dbase 7.0.0, returned as a bool (true or false), or null for uninitialized fields. Formerly, returned as an int (1 or 0).


As of dbase 7.0.0 nullable fields are supported for DBASE_TYPE_FOXPRO databases. If a field is nullable, passing null will set the respective flag, and on later retrieval the field value will be null.


There is no support for indexes or memo fields.
