Method column()
- Method
column
array column(array data, mixed index) - Description
Extract a column from a two-dimensional array.
This function is exactly equivalent to:
map(data , lambda(mixed x,mixed y) { return x[y]; }, index )
Except of course it is a lot shorter and faster.
That is, it indices every index in the array data on the value of
the argument index and returns an array with the results.
