在关联数组中搜索和替换

Question

我需要在关联数组中搜索和替换.

例如:

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

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

我想替换search1的search4.我怎样才能做到这一点？

更新:我忘了提到数组有几个search1值,我只想更改其中的值key is == $user.很抱歉没有提到这个.

Answer 1

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

foreach($myarray as $key => $val)
{
    if ($val == 'search1') $myarray[$key] = 'search4';
}
