PHP Multidimensional array php Two-dimensional array rectangle transpose

<?php        //two-D array transpose    //define a two-dimensional array    $arr =array (Array (), Array (4,5,6));    Defines an array to place the transpose data    $arr 1=array ();    Traverse Echo before transpose    "before transpose:";    for ($i =0; $i <count ($arr), $i + +) {for                ($j =0; $j <count ($arr [$i]); $j + +) {                    echo $arr [$i];                    }        echo "";    }    echo "Transpose before and after:";    Determine the number of lines after the appliance for    ($j =0; $j <count ($arr [0]), $j + +) {        $arr 1[$j]=array ();    }    for ($i =0; $i <count ($arr), $i + +) {for                ($j =0; $j <count ($arr [$i]); $j + +) {                    $arr 1[$j] [$i]= $arr [$i] [$j];            echo $arr;        }    }    Traverse after transpose: for    ($k =0; $k <count ($arr 1); $k + +) {for                ($l =0; $l

The above introduces PHP multidimensional array php Two-dimensional array of the rectangle transpose, including the contents of the PHP multidimensional array, I hope that the PHP tutorial interested in a friend helpful.
