思路，用array_filter() 函数 过滤

array_filter() 函数使用

function test_odd($var)

{

return($var & 1);

}

$a1=array("a","b",2,3,4);

print_r(array_filter($a1,"test_odd"));

?>

PHP闭包 function() use(){}

闭包的语法很简单，需要注意的关键字就只有use，use意思是连接闭包和外界变量。

$a =function()use($b) {

}

代码

foreach ($listMenu as $key=>$val){

$dataArr[]=array_filter($res,function ($var)use ($val){

if($var['type']==$val['type']&&$var['min']==$val['min']) return true;

});

}

//数组降维处理

array_walk($dataArr, function(&$v) {$v = current($v);});

print_r($dataArr);

输出

Array

(

[0] => Array

(

[id] => 183

[type] => 0

[min] => 0

)

[1] => Array

(

[id] => 188

[type] => 1

[min] => 1

)

)

升级版

/**

*使用数组筛选

*

*/

static public function getMenuAll(){

$res=[]

//return self::reSort($result);

$item['pid'] = 0;

$result = self::screen($res,$item);

return $result;

}

/**

* 筛选数组方法

* @param $res

* @param $val

* @return array

*/

static public function screen($res,$val){

return array_filter($res,function ($var) use ($val){

if($var['type']==$val['type']&&$var['min']==$val['min']) return true;

});

}
