php获取二维数据组中某个字段的值

直接上才艺，在php>5.5中，目前来看没有用过小于5.5版本了

源数据,截一部分

array (size=10)
  0 => 
    array (size=6)
      'Field' => string 'ID' (length=2)
      'Type' => string 'bigint(20) unsigned' (length=19)
      'Null' => string 'NO' (length=2)
      'Key' => string 'PRI' (length=3)
      'Default' => null
      'Extra' => string 'auto_increment' (length=14)
  1 => 
    array (size=6)
      'Field' => string 'user_login' (length=10)
      'Type' => string 'varchar(60)' (length=11)
      'Null' => string 'NO' (length=2)
      'Key' => string 'MUL' (length=3)
      'Default' => string '' (length=0)
      'Extra' => string '' (length=0)
  2 => 
    array (size=6)
      'Field' => string 'user_pass' (length=9)
      'Type' => string 'varchar(255)' (length=12)
      'Null' => string 'NO' (length=2)
      'Key' => string '' (length=0)
      'Default' => string '' (length=0)
      'Extra' => string '' (length=0)

我们想要获取其中的Filed字段变成一维数据

$arr2 = array_column($desc, 'Field');

看结果打印：

array (size=10)
  0 => string 'ID' (length=2)
  1 => string 'user_login' (length=10)
  2 => string 'user_pass' (length=9)
  3 => string 'user_nicename' (length=13)
  4 => string 'user_email' (length=10)
  5 => string 'user_url' (length=8)
  6 => string 'user_registered' (length=15)
  7 => string 'user_activation_key' (length=19)
  8 => string 'user_status' (length=11)
  9 => string 'display_name' (length=12)

这样还是极给力的
