README
To convert a table to another format you have to define 3 parameters:
- A decoder which tries to decode the original format
- A coder which will generate the new table
- An association rule which helps the converter to make an appropriate conversion
Converter::convert(Decoder $decoder, AssociationRule $associationRule, Coder $coder);
##Simple examples
It inserts an xlsx file to mysql table using mysqli. It will use the xls header as column names of the mysql table:
Converter::convert(new XlsxCodec("test_file.xlsx"), new SimpleAssociationRule(), new MysqliCodec($connection,"table_name"));
It inserts an php array to mysql table using mysqli. It will use the array keys as column names of the mysql table:
$testArray = [ ["col1" => 2, "col2" => 3, "col3" => "yes"], ["col1" => 1, "col2" => 222, "col3" => "apple"], ]; Converter::convert(new ArrayCodec($testArray), new SimpleAssociationRule(), new MysqliCodec($connection,"table_name"));
##Codecs
Codec classes contain the coder and decoder implementation for an appropriate format.
ArrayCodec
$testArray = [ ["col1" => 2, "col2" => 3, "col3" => "yes"], ["col1" => 1, "col2" => 222, "col3" => "apple"], ]; //If you use ArrayCodec as Decoder you have to specify the input associative array. $arrayDecoder = new ArrayCodec($testArray); //If you use ArrayCodec as Coder you can leave the constructor blank. $arrayCoder = new ArrayCodec();
CsvCodec, XlsCodec, XlsxCodec
//If you use CsvCodec, XlsCodec or XlsxCodec as Decoder you have to specify the input file name. $csvDecoder = new CsvCodec("test_file.csv"); $xlsDecoder = new XlsCodec("test_file.xls"); $xlsxDecoder = new XlsxCodec("test_file.xlsx"); //If you use CsvCodec, XlsCodec or XlsxCodec as Coder you have two options. //First option: You specify the file name, thus the coder will write out the table in that file. Converter::convert(new CsvCodec("test_file.csv"), new SimpleAssociationRule(), new XlsxCodec("new_test_file.xlsx")); //Second option: If you don't set the filename parameter, the coder will return with the file as a string. $xls = Converter::convert(new CsvCodec("test_file.csv"), new SimpleAssociationRule(), new XlsxCodec());
MysqliCodec
//If you use MysqliCodec as Coder, you have to set the mysqli connection and the name of the table $db = new mysqli('localhost', 'user', 'pass', 'demo'); if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error . ']'); } $mysqliCoder = new MysqliCodec($db,"table_name"); //If you use MysqliCodec as Decoder, you have to more options. Firstly, you can use as same as in Coder. It will //select the whole table with all column. $mysqliDecoder = new MysqliCodec($db,"table_name"); //Another option is that you write an arbitrary sql query. In this case, you can leave the table name empty. $mysqliDecoder = new MysqliCodec($db,"","SELECT * FROM table_name WHERE col1 > 5 OR col2 = 44"); $mysqliDecoder2 = new MysqliCodec($db,"","SELECT * FROM table_name JOIN table_name2 ON (table_name.id = table_name2.id)");
