I am trying to split a variable only if it has an integer. Here is what I want to do: $id = 1234-54678; should be split into and then placed into two variables: $id1 = 54678; $id2 = 1234; Sometimes the variable may not have a delimiter in which case I would like it to be $id1 example: $id = 54678; should go directly to $id1 = 54678; I am a php rookie and don't know which way is best to do this (explode, split, etc.) so I would appreciate any help you can give me.
