PHP two-dimensional array and three-dimensional array filtering, PHP two-dimensional array array
No more nonsense, I will post the code directly for you. The specific code is as follows:
<?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);
The following code will introduce to you how to convert a php three-dimensional array into a two-dimensional array
<?php $result = Array(0 => Array(0 => Array(bid => 41,brealname => 'we教官',cid => 41,crealname => 'we教官')), 1 => Array(0 => Array(bid => 6,brealname => '虎子',cid => 19,crealname => '张鱼')) ); //原数组 print_r($result); echo "<br />"; //第一种方法: foreach ($result as $key =>$v){ $new_arr[]=$v[0]; } echo '<pre class="brush:php;toolbar:false">'; print_r($new_arr); //第二种方法 //初始化$arr2 $arr2=array(); //循环遍历三维数组$arr3 foreach($result as $value){ foreach($value as $v){ $arr2[]=$v; } } //销毁$arr3 unset($result,$value,$v); echo "<br /s>"; echo "第二种方法:"; echo '<pre class="brush:php;toolbar:false">'; print_r($arr2); ?>
