问题描述
My array : 
我的阵列：
<?php
$hoppa = array
(
"0" => array
("0","0","0","0","0","0","0","0","0","0"),
"1" => array
("0","0","0","0","0","0","0","0","0","0"),
"2" => array
("1","0","0","1","0","0","0","0","0","0"),
"3" => array
("1","0","0","1","0","1","1","1","1","0"),
"4" => array
("1","1","1","1","0","0","0","0","1","0"),
"5" => array
("1","0","0","1","0","1","1","1","1","0"),
"6" => array
("1","0","0","1","0","1","0","0","1","0"),
"7" => array
("1","0","0","1","0","1","1","1","1","0"),
"8" => array
("0","0","0","0","0","0","0","0","0","0"),
"9" => array
("0","0","0","0","0","0","0","0","0","0")
);
?>
My array's output: 我的数组的输出：

[5] => 0
[6] => 0
[7] => 0
[8] => 0
[9] => 0
)
)
it will give 0 (zero) as result 结果将为0（零）
echo $hoppa[1][1];
it will give 1 (one) as result 结果将是1（一）
echo $hoppa[2][0];
I dont want 0 (zero) values to show in the results. 我不希望在结果中显示0（零）值。 I want php script to return only 1 as results. 我希望php脚本只返回1作为结果。 Which functions should use? 应该使用哪些功能？ or can you give me a sample? 还是可以给我样品？

Use: 采用：
foreach($hoppa as $k => $v) {
$hoppa[$k] = array_filter($v);
}
This results in: 这导致：
php > print_r($hoppa);
