Activate debug to run cron functions PHP in Ubuntu

I have this code: run_jobs() { printf "$(date) : $$ start\n" get_lock check_bitcoind # check whether bitcoind is running, and if not, run it #backup_database "before cron" sync_to_bitcoin; #backup_database "synced bitcoin" # check for and process new btc deposits verify_deposits; #backup_database "verified deposits" # check for and process new deposits verify_withdrawals_bitcoin; #backup_database "verified bitcoin withdrawals" # check for and process new bitcoin withdrawals process_orders; #backup_database "processed orders" # check for and process new orders log_process_sizes >> $LOGDIR/[login to view URL] release_lock printf "$(date) : $$ end\n\n" } But when run in SSH no error appear root@az:/home/intersango/bin# ./every-minute root@az:/home/intersango/bin# ./every-minute I need activate debug options to see why is not running the PHP code inside functions example process_orders() { printf "$(date) : $$ processing orders\n" mkdir -p $LOGDIR/process_orders ( cd $CRON php ./[login to view URL] > $LOGDIR/process_orders/$(date +%y.%m.%d-%H.%M.%S) 2>&1 ) # delete small logfiles find $LOGDIR/process_orders '(' -size 484c -o -size 118c ')' -delete } Because when I run from SSH php ./[login to view URL] it work fine! But when run from ./every-minute cron file it show no error and not run .php database updates.
