php多维数组检索

来源: 互联网发布时间：2014-10-10

本文导语: 1，php搜索多维数组的键值例子: 代码示例: $foo[1]['a']['xx'] = 'bar 1'; $foo[1]['b']['xx'] = 'bar 2'; $foo[2]['a']['bb'] = 'bar 3'; $foo[2]['a']['yy'] = 'bar 4'; $foo[3]['c']['dd'] = 'bar 3'; $foo[3]['f']['gg'] = 'bar 3'; $foo['info'][1] = 'bar 5'; 如果要查找 bar 3 ...

1，php搜索多维数组的键值
例子:

代码示例:

$foo[1]['a']['xx'] = 'bar 1';

$foo[1]['b']['xx'] = 'bar 2';

$foo[2]['a']['bb'] = 'bar 3';

$foo[2]['a']['yy'] = 'bar 4';

$foo[3]['c']['dd'] = 'bar 3';

$foo[3]['f']['gg'] = 'bar 3';

$foo['info'][1] = 'bar 5';

如果要查找 bar 3 怎么进行查找呢。有三个结果，而这三个结果都要，看下面的函数：

代码示例:

function array_search_re($needle, $haystack, $a=0, $nodes_temp=array()){

global $nodes_found;

$a++;

foreach ($haystack as $key1=>$value1) {

    $nodes_temp[$a] = $key1;

    if (is_array($value1)){   

      array_search_re($needle, $value1, $a, $nodes_temp);

    }

    else if ($value1 === $needle){

      $nodes_found[] = $nodes_temp;

    }

}

return $nodes_found;

}

这个函数就可以把上面要查找到的内容全部返回出键名来

代码示例:

$result = array_search_re('bar 3', $foo);

print_r($result);

输出结果：
Array ( [0] => Array ( [1] => 2 [2] => a [3] => bb )
          [1] => Array ( [1] => 3 [2] => c [3] => dd )
          [2] => Array ( [1] => 3 [2] => f [3] => gg )
        )

2，php搜索多维数组的键名

代码示例:

return $nodes_found;
}
$result = array_search_key('a', $foo);

print_r($result);

输出结果：
Array
(
    [0] => Array
        (
            [xx] => bar 1
        )

    [1] => Array
        (
            [bb] => bar 3
        )

    [2] => Array
        (
            [yy] => bar 4
        )
)
