Create a list of texts which are seperated by '+' and '-' : I have a text in following manner
`@@+aaa+bbb+ccc-asd-asdfg+hhh`

I need to separate the text and save it in a list such that the entries of the list are 'aaa','bbb','ccc','asd','asdfg','hhh' <br>

I did `$str = substr($str1,2); ` to remove the '@@'
