php中搜索多维数组的键值程序

如下面例子:

代码如下	复制代码
$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：
-------------------------------------------------------------------------------------------------------------------------------

代码如下	复制代码
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

代码如下

复制代码

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

print_r($result);

输出结果为如下：
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 )
        )

1 php搜索多维数组的键名

代码如下

复制代码

function array_search_key($needle, $haystack){
global $nodes_found;

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

if ($key1=== $needle){

$nodes_found[] = $value1;

   }
    if (is_array($value1)){
      array_search_key($needle, $value1);
    }


}

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

print_r($result);

输出结果为如下：

代码如下

复制代码

Array
(
    [0] => Array
        (
            [xx] => bar 1
        )

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

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

)

类似全文匹配！用二个循环第一个循环keys 第二个模糊匹配用函数strstr() 来解决
