PHP 二維數組和三維數組的過濾_php執行個體

廢話不多說了，直接給大家貼代碼了，具體代碼如下所示：

<?php$arr = [[,,,,],[,,,,]];$arr = ['list' => [[,,,],[,,,],[,,,],]];$arr = ['list' => [[,,,],[,,,],[,,,]]];$res = array_map(function($arr){return array_filter($arr, function($v) {return $v !== ;});}, $arr);$res = array_map(function($val) {return array_filter($val, function($v) {return !in_array(, $v);});}, $arr);$res = [];array_walk($arr, function($val, $key) use(&$res) {$res[$key] = array_filter($val, function($v) {return !in_array(, $v);});});var_dump($res);var_dump($res);

下面一段代碼給大家介紹php三維數組變二維數組

<?php$result = Array(0 => Array(0 => Array(bid => 41,brealname => 'we教官',cid => 41,crealname => 'we教官')),1 => Array(0 => Array(bid => 6,brealname => '虎子',cid => 19,crealname => '張魚')));//原數組print_r($result);echo "<br />";//第一種方法：foreach ($result as $key =>$v){$new_arr[]=$v[0];}echo '<pre>';print_r($new_arr);//第二種方法//初始化$arr2 $arr2=array(); //迴圈遍曆三維數組$arr3 foreach($result as $value){ foreach($value as $v){ $arr2[]=$v; } }//銷毀$arr3 unset($result,$value,$v);echo "<br /s>";echo "第二種方法：";echo '<pre>';print_r($arr2);?>

關於PHP 二維數組和三維數組的過濾小編就給大家介紹這麼多，希望對大家有所協助！
