TokyoTyrantIterator::__construct — Construct an iterator

说明

public TokyoTyrantIterator::__construct ( mixed $object )

Construct a new TokyoTyrantIterator object. One connection can have multiple iterators but it is not quaranteed that all items are traversed in that case. object parameter can be either an of instance TokyoTyrant or TokyoTyrantTable.

参数

此函数没有参数。

返回值

Throws an exception if iterator initialization fails.

范例

Example #1 TokyoTyrantIterator::__construct() example

 <?php
/* Connect to a table database */
$tt = new TokyoTyrantTable("localhost", 1979);

/* Passing null to put generates a new uid */
$index = $tt->put(null, array("column1" => "some data", "column2" => "more data"));

/* Construct an iterator */
$it = new TokyoTyrantIterator($tt);

foreach ($it as $value) {
    var_dump($value);
}
?>

以上例程会输出：

array(2) {
  ["column1"]=>
  string(9) "some data"
  ["column2"]=>
  string(9) "more data"
}
