过滤数组结果
提问于 2011-01-28 10:20:54
我的数组：
<?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")
);
?>我的数组的输出：
Array
(
[0] => Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
[4] => 0
[5] => 0
[6] => 0
[7] => 0
[8] => 0
[9] => 0
)
[1] => Array

)
[3] => Array

[3] => 1
[4] => 0
[5] => 1
[6] => 1

)

[3] => 1
[4] => 0
[5] => 0
[6] => 0
[7] => 0
[8] => 1
[9] => 0
)
[5] => Array
(
[0] => 1
[1] => 0
[2] => 0
[3] => 1
[4] => 0
[5] => 1
[6] => 1
[7] => 1
[8] => 1
[9] => 0
)
[6] => Array
(
[0] => 1
[1] => 0
[2] => 0
[3] => 1
[4] => 0
[5] => 1
[6] => 0
[7] => 0
[8] => 1
[9] => 0
)
[7] => Array
(
[0] => 1
[1] => 0
[2] => 0
[3] => 1
[4] => 0
[5] => 1
[6] => 1
[7] => 1
[8] => 1
[9] => 0
)
[8] => Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
[4] => 0
[5] => 0
[6] => 0
[7] => 0
[8] => 0
[9] => 0
)
[9] => Array
(
[0] => 0
[1] => 0
[2] => 0
[3] => 0
[4] => 0
[5] => 0
[6] => 0
[7] => 0
[8] => 0
[9] => 0
)
)它将给出0(零)作为结果
echo $hoppa[1][1];它将给出1(1)作为结果
echo $hoppa[2][0];我不希望在结果中显示0(零)值。我希望php脚本只返回1作为结果。应该使用哪些函数？或者你能给我一个样品吗？

使用：
foreach($hoppa as $k => $v) {
$hoppa[$k] = array_filter($v);
}这将导致：
php > print_r($hoppa);
