获取数组中键的值

Question

如何获取数组中键的值？ 我的数组就像：

$array = array(
  array(key1 => "value1", key2 => "value2", key3 => "value3"),
  array(key1 => "value1", key2 => "value2", key3 => "value3"),
  array(key1 => "value1", key2 => "value2", key3 => "value3"),
  array(key1 => "value1", key2 => "value2", key3 => "value3")
);

foreach($array as $row) {
  $key1 = $row['key1'];
  $key2 = $row['key2'];
  $key3 = $row['key3'];
}

//所以应该可以写例如echo $ ke1，然后得到out value1或echo $ key2并得到输出：value 2等等......

这怎么可能？希望有人理解我:)。

这是你要找的吗？

foreach($array as $row) {
    foreach($row as $key => $value) {
        // first iteration, $key == key1, $value = 'value1'
    }
}
