搜索和关联数组内更换 [英] Search and replace inside an associative array

问题描述

我要搜索和关联数组内更换。

例如：

  $ USER =USER1; //我已经更新了此$ myArray的=阵列（用户1=＆gt;中搜索1，用户2=＆gt;中搜索2，用户3=＆gt;中搜索1）;
 

我要替换搜索1 为 search4 。我怎样才能做到这一点？

更新：我忘了​​提，数组有几个搜索1 的价值观和我只是想改变的值，其中键== $用户。对不起，没有提到这点。

解决方案

  $ USER =USER1;
$ myArray的=阵列（用户1=＆gt;中搜索1，用户2=＆gt;中搜索2，用户3=＆gt;中搜索1）;
的foreach（$ myarray中为$关键=＆GT; $ VAL）
{
    如果（$ VAL =='搜索1和$关键== $用户）
    {
    $ myArray的[$关键] ='search4';
    打破;
    }
}
的print_r（$ myarray的）;
 

打印：

 阵列
（
    [USER1] =＆GT; sea​​rch4
    [用户2] =＆GT;搜索2
    [用户3] =＆GT;搜索1
）
 

I need to search and replace inside an associative array.

ex:

$user = "user1"; // I've updated this

$myarray = array("user1" => "search1", "user2" => "search2", "user3" => "search1" ) ;

I want to replace search1 for search4. How can I achieve this?

UPDATE: I forgot to mention that the array has several search1 values and I just want to change the value where the key is == $user. Sorry for not mention this earlier.

解决方案

$user = "user1";
$myarray = array("user1" => "search1", "user2" => "search2", "user3" => "search1" );
foreach($myarray as $key => $val)
{
    if ($val == 'search1' and $key == $user )
    {
    $myarray[$key] = 'search4';
    break;
    }
}
print_r($myarray);

Prints:

Array
(
    [user1] => search4
    [user2] => search2
    [user3] => search1
)
