Replace all array values with a single string

How can I replace all the values of an array with a single $string.

For example I have this :

$string = "myString";

$array = array(
   'key1' => 'value1',
   'key2' => 'value2',
   'key3' => 'value3', 
);

I want to output this :

$replacedArray = array(
   'key1' => 'myString',
   'key2' => 'myString',
   'key3' => 'myString', 
);

How can I replace all the values of an array with a $string.

Use array_map() and return 'myString'. This will give you a new array.

$replacedArray = array_map(function() { return 'myString'; }, $array);

If you want to change them in place, you could use a loop or any other function that mutates the original array.

Use an array_walk() [This function modifies your original array itself]

array_walk($array, function(&$v) use($string) { $v = $string;});
$replacedarray = $array; //<--- If you want the results in another array.

Go with Alex's answer, If you want the result in another variable.
