These functions allow you to access records stored in dBase_format
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:
Table 1. 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|
You must declare a length and a precision (the number of digits
after the decimal point)
|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.|
|L||Boolean||T or Y for TRUE,
F or N for FALSE||Stored and returned as an integer (1 or 0)|
|F||Float||A float number||Support for this type of field was added in PHP 5.2.0|
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
In order to enable the bundled dbase library and to use these functions,
you must compile PHP with the --enable_dbase

Many examples in this reference require a dBase database. We will use
