Here is an example array:
array(
array("1","2"),
array("2","3"),
array("3","1")
)
now suppose I get some form inputs with the value 1 and 1. I am trying to
find a way to figure out if the first coloumn is already in the table and if
so just add the second coloumn to the first. I have tried various
combinations of foreaches, in_array and array_search.
Has anyone had a similar problem and found a soloution?
