废话不多说,直接贴上代码。本文体现的就是简洁

代码如下:


 
//删除目录下所有空目录
array_map('rmdir', glob('*', GLOB_ONLYDIR));
 
//删除目录所有文件
array_map('unlink', array_filter(glob('*'), 'is_file'));

使用array_map实现array_column功能:

代码如下:


$data = array(
    array(
        'a' => 'first a',
        'b' => 'first b'
    ),
    array(
        'a' => 'second a',
        'b' => 'second b'
    )
);
 
$array_column = array_map(function($element){
    return $element['a'];
}, $data);
 
print_r($array_column);
