If you have xls or ods file with data. You can open file in OpenOffice Calc and save the table as dbf (dBase file) and the use this extension to manipulate data.
Usualy this gives better results than just saving as XML. or CSV.
Introduzione
Nota:
Questo modulo è stato spostato nel repository » PECL e non è più rilasciato con il PHP dalla versione 5.3.0.
These functions allow you to access records stored in dBase-format (dbf) databases.
Avviso
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.
Attenzione
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:
| 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).
|
Nota:
As of dbase 7.0.0 nullable fields are supported for
DBASE_TYPE_FOXPROdatabases. If a field is nullable, passingnullwill set the respective flag, and on later retrieval the field value will benull.
Nota:
There is no support for indexes or memo fields.
