    If I want to have arrays in a form I do something like this:
    <input type='hidden' name='myName' value='something'/>
<input type='hidden' name='myName' value='something'/>
    PHP:
    So I can get the value of tags by document.formName.myName[0].value.

    But since I need to read the data through php after submitting the form I have to change it to name='myName[]'.

    Question: how do I get the value of myName now? This time document.formName.myName[0].value wouldn't work.

    document.formName.elements["myName[]"] returns the array.
    each element can then be accessed as usual.
    e.g.: document.formName.elements["myName[]"][0].value
