如何在php

Question

我卡在一点上我有两个数组，一个包含读数据，另一个包含写，如下所示

读取数组

    Array
(
    [0] => master/city
    [1] => master/national_holiday
    [2] => master/operator_comments
    [3] => master/sensors
)

写数组

Array
(
    [0] => master/city
    [1] => master/national_holiday
)

我想结合这两个数组。我想要如下

    Array
(
    ['master/city'] => 'read/write'
    ['master/national_holiday'] => 'read/write'
    ['master/operator_comments'] => 'read'
    ['master/sensors'] => 'read'
)

这样可能吗？

Answer 1

你可以这样做：

这是DEMO

$final = [];
array_walk($read,function($v,$k) use (&$final,&$write){
    if(array_search($v,$write) > -1){
        $final[$v] = 'read/write';
    }
    else{
        $final[$v] = 'read';
    }
});
print_r($final);

<强>输出

Array
(
    [master/city] => read/write
    [master/national_holiday] => read/write
    [master/operator_comments] => read
    [master/sensors] => read
)

修改 根据与Dhanashri：

的讨论，请检查此项以获得更好的结果

$read_flipped = array_flip($read);
$read_new = array_fill_keys(array_keys($read_flipped), 'read');               

$write_flipped = array_flip($write);
$write_new = array_fill_keys(array_keys($write_flipped), 'write');



$final = [];
$arr3 = array_merge_recursive($read_new,$write_new);

array_walk($arr3,function($v,$k) use (&$final) {
    if(is_array($v)){
        $final[$k] = 'read/write';
    }
    else{
        $final[$k] = $v;
    }
});
print_r($final);

Answer 2

var="rule:access=allow,OTHER=0,SOMETHING=1"

O / P

 $read = array
(
    "master/city",
    "master/national_holiday",
    "master/operator_comments",
    "master/sensors",
);

$write = array(
    "master/city",
    "master/national_holiday",
 );


$new_array = array_merge($read,$write);
$your_array = array();
foreach($new_array as $key => $value ){ 
         $your_array[$value] =  (array_key_exists($value,$your_array)) ? "read/write" :  "read";
}
var_dump($your_array);

你也可以使用

做同样的事情

array (size=4)
  'master/city' => string 'read/write' (length=10)
  'master/national_holiday' => string 'read/write' (length=10)
  'master/operator_comments' => string 'read' (length=4)
  'master/sensors' => string 'read' (length=4)

Answer 3

   // we need somed 
   $read = array('master/city',
          'master/national_holiday',
          'master/operator_comments',
            'master/sensors');
  // Write variable 
 $write = array('master/city','master/national_holiday');

 $newarray = array();
 foreach($read as $key => $value)
 {
 // check value in another array 
 if(in_array($value,$write))
  {
    $access = 'read/write';
  }
 else
  {
    $access = 'read';
  }

 $newarray[$value] = $access;
 }

print_r($newarray);
