php 控制台打印二维数组

使用

use console\models\PrintTable;

$arr=[
    ['a'=>'aaaa','b'=>'bbbb','c'=>'cbbbb','d'=>'dbbb','e'=>'ebbb','f'=>'fbbb','g'=>'gbbb'],
    ['a'=>'a','b'=>'b','c'=>'c','d'=>'d','e'=>'e','f'=>'f','g'=>'g'],
    ['a'=>'a','b'=>'b','c'=>'c','d'=>'d','e'=>'e','f'=>'f','g'=>'g'],
    ['a'=>'a','b'=>'b','c'=>'c','d'=>'d','e'=>'e','f'=>'f','g'=>'g'],
    ['a'=>'a','b'=>'b','c'=>'c','d'=>'d','e'=>'e','f'=>'f','g'=>'g'],
    ['a'=>'a','b'=>'b','c'=>'c','d'=>'d','e'=>'e','f'=>'f','g'=>'g'],
];
echo PrintTable::Print_table($arr);

效果
