PHP array_keys多个级别

Question

我已经ARRAY1这样的：

Array 
(
[0] => 123 
[1] => 456 
[2] => 789 
) 

和阵列2这样

Array 
(

[0] => Array 
    (
     [0] => some text 
     [1] => 888 
     [2] => some 
     [3] => text 
    ) 
    [1] => Array 
    (
     [0] => some text 
     [1] => 123 
     [2] => some 
     [3] => text 
    ) 
    [2] => Array 
    (
     [0] => some text 
     [1] => 999 
     [2] => some 
     [3] => text 
    ) 
    [3] => Array 
    (
     [0] => some text 
     [1] => Array 
      (
       [1] => 456 
       [2] => 789 
      ) 
     [2] => some 
     [3] => text 
    ) 
    [4] => Array 
    (
     [0] => some text 
     [1] => 123 
     [2] => some 
     [3] => text 
    ) 
) 

我检查仅1.第二阵列的列和寻找从第一匹配值该值阵列。这是我的代码：

$test=array(); 

$xcol = array_column($array2, 1); 
foreach($array1 as $key => $value) { 
if(($foundKey = array_keys($xcol, $value)) !== false) { 
$rrt=$foundKey; 
foreach($rrt as $rte){ 
    $test[]=$array2[$rte]; 
} 
} 
} 

echo "<pre>"; 
print_r($test); 
echo "</pre>"; 

这是工作，给我适当的结果，但它不检查所有级别。任何人都可以请指出我做错了什么？ 我的输出是：

Array 
(

    [0] => Array 
    (
     [0] => some text 
     [1] => 123 
     [2] => some 
     [3] => text 
    ) 
    [1] => Array 
    (
     [0] => some text 
     [1] => 123 
     [2] => some 
     [3] => text 
    ) 
    ) 

和期望的输出是：

Array 
(

    [0] => Array 
    (
     [0] => some text 
     [1] => 123 
     [2] => some 
     [3] => text 
    ) 
    [1] => Array 
    (
     [0] => some text 
     [1] => Array 
      (
       [1] => 456 
       [2] => 789 
      ) 
     [2] => some 
     [3] => text 
    ) 
    [2] => Array 
    (
     [0] => some text 
     [1] => 123 
     [2] => some 
     [3] => text 
    ) 
    ) 

Answer 1

解决方案：

创建一个循环，其循环您$array2持有你想获得卫生组织值相匹配的第一个数组DATAS $array1

foreach($array2 as $data) { 

内循环创建另一个循环，其循环控制指标

foreach($data as $value) { 

但是之前创造条件，如果你的索引值是数组循环，并检查它，它的索引值是比赛从$array1使用PHP函数in_array任何索引为

 if (gettype($value) == "array") { 
      foreach($value as $val) { 
       if (in_array($val, $array1)) { 
        $result[] = $data; 

然后，如果你发现它只是用break避免停止循环重复

    break; 
       } 
      } 

否则你只是直接使用in_array

 } else if (in_array($value, $array1)) { 
      $result[] = $data; 
     } 
    } 
}

让我们做这个递归方法。什么是你问的递归？那么它只是一种称为自我的方法。

<?php 
$array1 = array(123,456,789); 
$array2 = array(
    array(
     "some text" 
     , 888 
     , "some" 
     , "text" 
    ), 
    array(
     "some text" 
     ,123 
     ,"some" 
     ,"text" 
    ), 
    array(
     "some text" 
     ,999 
     ,"some" 
     ,"text" 
    ), 
    array(
     "some text" 
     ,array(456,789) 
     ,"some" 
     ,"text" 
    ), 
    array(
     "another text" 
     ,123 
     ,"some" 
     ,"text" 
    ) 
); 
$final = array(); 
foreach($array1 as $needle){ 
    foreach($array2 as $haystack){ 
     if(find($needle,$haystack)){ 
      $final[] = $haystack; 
     } 
    } 
} 

print_r($final); 

function find($needle, $haystack){ 
    $result = false; 
    foreach ($haystack as $value) { 
     if(is_array($value)){ 
      $result = find($needle, $value); 
     } else { 
      if($needle == $value){ 
       $result = true; 
      } 
     } 
    } 
    return $result; 
}
