Constructor Detail

DataTableResult

public DataTableResult(mixed data, mixed uri)

Method Detail

num_fields

public void num_fields()

Returns the number of fields in the result set.

num_rows

public void num_rows()

Returns the number of rows in the result set.

result

public void result()

Returns the query result as an array of objects, or an empty array on any failure. Each field in the original query is mapped to an object variable.

For example:

 $dt = new DataTable('http://api.talis.com/stores/mystore');
 $dt->map('http://xmlns.com/foaf/0.1/name', 'name');
 $dt->map('http://xmlns.com/foaf/0.1/nick', 'nick');
 $dt->select('name,nick')->limit(10);
 $res = $dt->get();
 foreach ($res->result() as $row) {
    echo $row->name;
    echo $row->nick;
 }
 

result_array

public void result_array()

Returns the query result as an array of associative arrays, or an empty array on any failure. The keys and values of the associative array correspond with the fields and values in the results.

For example:

 $dt->select('name,nick')->limit(10);
 $res = $dt->get();
 
foreach ($res->result_array() as $row) {
    echo $row['name'];
    echo $row['nick'];
 }
 

row

public void row(mixed index)

row_array

public void row_array(mixed index)

Returns an associative array containing a single result row. The $index parameter is optional and defaults to zero.

rowdata

public void rowdata(mixed index)

Returns an associative array containing metadata about the values in the specified row. The array keys correspond to field names and the values to another associative array containing the metadata for that field's value. The $index parameter is optional and defaults to zero.

The following metadata keys are available:

• type - the type of the field's value, one of "uri", "bnode" or "literal"
• datatype - the datatype of a literal value, or null if no datatype was detected
• lang - the language code of a literal value, or null if no language was detected

 $dt->select('name,nick')->limit(10);
 $res = $dt->get();
 $rowdata = $res->rowdata(5);
 echo $rowdata['name']['type'];
 echo $rowdata['name']['lang'];
 echo $rowdata['name']['datatype'];
 

to_string

public void to_string()

Returns a tabular string representation of the results.
