Answer 1

You can do this with a following statement:

str_replace(find,replace,string,count)

Answer 2

<?php
    $input = fopen("myfile.txt", "r");
    while(!feof($input)) {
        //echo fgets($input). "<br>";
$str = fgets($input);
$searchVal = array("aaa", "bbb", "ccc");
$replaceVal = array("fff", "ggg", "hhh");
$res = str_replace($searchVal, $replaceVal, $str);
echo ($res). "<br>";

    }
?>
