Here, a string is defined, and the string that needs to be replaced with a different string is placed inside an array and arranged to a variable −

$my_str = "This is a sample only";$search_str = array("sample", "This");
$replace_str = array("simple"); The ‘str_replace’ function is used to replace the value with a different specified value. The result is printed on the screen − $result = str_replace($search_str,$replace_str, $my_str); print_r("The final replaced string is :"); print_r($result);
