Here is a quick tip for when you want to replace some text in your code.
Say that you have many HTML attributes like
name="email" and you want to replace them with
name="<?= $field['email']['name']; ?>". Then you must search for
name="(w+?)" and replace with
name="<?= $field['1']['name'] ?>". Note that you need to escape the $ with a backslash for Eclipse to do its work. If you omit it, Eclipse will simply not work and not complain.
