Make sure that:
- The user executing the script (apache I presume) has execute
permissions on ls and ln binaries.
- The user executing the script has write persmissions on the
directory you are trying to write, and read permissions where you do
ls.
- This will probably help: put the full binary path for ls and ln, it
depends on your OS, but probably they are: /bin/ls and /bin/ln
If that doesn't help, can you show us the output?
