获取数组中的键的值

Question

如何获取数组中的键的值？ 我的阵列是这样的：

$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']; 
} 

//所以它应该是可以写例如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？希望有人能理解我:)

这是你在找什么？

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