myarray=array()
myarray['a']=1 myarray['b']=1 myarray['c']=1 Is there an iterative way to find out the array index values ('a', 'b' and 'c') of myarray? |

foreach ($myarray as $key => $value)

Note, however, that array_keys is not recursive.

foreach is also not recursive, writing a recursive function to recursively
return the keys in an array should be trivial. |
