PHP two-dimensional array and three-dimensional array filter, PHP two-dimensional array of arrays

Not much nonsense to say, directly to everyone to paste the code, 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);

Here is a piece of code to introduce PHP three-dimensional array variable two-dimensional array

<?php$result = Array (0 = = Array (0 = = Array (bid + 41,brealname = ' We instructor ', cid = 41,crealname = ' We instructors '), 1 = = Array (0 = = Array (bid + 6,brealname = ' no ', cid = 19,crealname = ' Zhang Fish ')));//original array print_r ($result ); echo "
";///First method: foreach ($result as $key + $v) {$new _arr[]= $v [0];} Echo '
;p Rint_r ($new _arr);//The second method//Initialize $ARR2 $arr 2=array ();//Loop through a three-dimensional array $arr3 foreach ($result as $value) {foreach ($value as $v) {$arr 2[]= $v;}} Destruction of $arr3 unset ($result, $value, $v); echo "
"; echo "the second method:"; Echo ' 
;p Rint_ R ($arr 2);?
