这篇文章主要介绍了使用array_map简单搞定PHP删除文件、删除目录的相关资料,需要的朋友可以参考下
废话不多说,直接贴上代码。本文体现的就是简洁
复制代码 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:
复制代码 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);
