A simple library for dealing with dbf databases like dBase and FoxPro. It's a port of PHPXbase class written by Erwin Kooi, updated to a PSR-2 compliant code and tweaked for performance and to solve some issues the original code had.
You can install it through Composer:
$ composer require hisamu/php-xbaseMore samples in tests folder.
use XBase\TableReader;
$table = new TableReader('test.dbf');
while ($record = $table->nextRecord()) {
echo $record->get('my_column');
//or
echo $record->my_column;
}If the data in DB is not in UTF-8 you can specify a charset to convert the data from:
use XBase\TableReader;
$table = new TableReader(
'test.dbf',
[
'encoding' => 'cp1251'
]
);It is also possible to read Memos from dedicated files. Just make sure that .fpt file with the same name as main database exists.
You can pass an array of the columns that you need to the constructor, then if your table has columns that you don't use they will not be loaded. This way the parser can run a lot faster.
use XBase\TableReader;
$table = new TableReader(
'test.dbf',
[
'columns' => ['my_column', 'another_column']
]
);
while ($record = $table->nextRecord()) {
echo $record->my_column;
echo $record->another_column;
}If you know the column type already, you can also call the type-specific function for that field, which increases the speed too.
while ($record = $table->nextRecord()) {
echo $record->get('my_column');
echo $record->get('another_column');
}To open a table for editing, you have to use a TableEditor object, as on this example:
use XBase\TableEditor;
$table = new TableEditor('test.dbf');
for ($i = 0; $i < 10; $i++) {
$record = $table->nextRecord();
$record->set('field', 'string');
//or
$record->field = 'string';
$table->writeRecord();
}
$table
->save()
->close();use XBase\TableEditor;
$table = new TableEditor(
'file.dbf',
[
'editMode' => TableEditor::EDIT_MODE_CLONE, //default
]
);
$record = $table->appendRecord();
$record->set('name', 'test name');
$record->set('age', 20);
$table
->writeRecord()
->save()
->close();use XBase\TableEditor;
$table = new TableEditor('file.dbf');
while ($record = $table->nextRecord()) {
if ($record->get('delete_this_row')) {
$table->deleteRecord(); //mark record deleted
}
}
$table
->pack() //remove deleted rows
->save() //save changes
->close();To create a table file you need to use the TableCreator object.
use XBase\Enum\FieldType;
use XBase\Enum\TableType;
use XBase\Header\Column;
use XBase\Header\HeaderFactory;
use XBase\TableCreator;
use XBase\TableEditor;
// you can specify any other database version from TableType
$header = HeaderFactory::create(TableType::DBASE_III_PLUS_MEMO);
$filepath = '/path/to/new/file.dbf';
$tableCreator = new TableCreator($filepath, $header);
$tableCreator
->addColumn(new Column([
'name' => 'name',
'type' => FieldType::CHAR,
'length' => 20,
]))
->addColumn(new Column([
'name' => 'birthday',
'type' => FieldType::DATE,
]))
->addColumn(new Column([
'name' => 'is_man',
'type' => FieldType::LOGICAL,
]))
->addColumn(new Column([
'name' => 'bio',
'type' => FieldType::MEMO,
]))
->addColumn(new Column([
'name' => 'money',
'type' => FieldType::NUMERIC,
'length' => 20,
'decimalCount' => 4,
]))
->addColumn(new Column([
'name' => 'image',
'type' => FieldType::MEMO,
]))
->save(); //creates file
$table = new TableEditor($filepath);
//... add records I'm not an expert on dBase and I don't know all the specifics of the field types and versions, so the lib may not be able to handle some situations. If you find an error, please open an issue and send me a sample table that I can reproduce your problem, and I'll try to help.
