Search and replace inside an associative array

Question

I need to search and replace inside an associative array.

ex:

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

$myarray = array(\"user1\" => \"search1\",         


        

Answer 1

Following on from Joseph's answer, using preg_replace may enable you to use the code in other situations:

function pregReplaceInArray($pattern,$replacement,$array) {
    foreach ($array as $key => $value) {
        $array[$key] = preg_replace($pattern,$replacement,$value);
    }   
    return $array;
}

Answer 2

$originalArray = array( "user1" => "search1" , "user2" => "search2" );
$pattern = 'search1';
$replace = 'search4';

$replacedArray = preg_replace( '/'.$pattern.'/' , $replace , $originalArray );

Fixes the risk mentioned in comment in response to this solution

Answer 3

Using str_replace should work:

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

$newArray = str_replace('search1', 'search4', $myarray);

Answer 4

if you want for particular key then you just add condition for key in previous ans like.

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

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