i am trying to create a function to replace all instances of 'sam' with 'paul' within the values of the following array.  can someone give me a bit of a hand?

 

$name = array('key1'=>'sam1', 'key2'=>'value2', 'key3'=>array('sam','sam1','sam2'));

 

$str1 = “sam";

$str2 = “paul”;

 

foreach ($name as $value)

{

if($value == $str1){

$value = $str2;}

}

what thorpe suggested will work only for single dimension array. Try this:-

 

$name = array('key1'=>'sam', 'key2'=>'value2', 'key3'=>array('sam','sam1','sam2'));



function replaceVal(&$item){
$search = 'sam';
$replace = 'paul';
if($search == $item){
	$item = $replace;
}
}

array_walk_recursive($name, "replaceVal");
echo "<pre>";
print_r($name);
echo "</pre>";
