I wrote up this quick little banking script to illustrate how to do simple object oriented programming in php5 using classes. Functions within a class are known as methods.
-JJ
class account_transact
{
var $balance;
var $account_type;
var $amount;
function get_bal($account_type)
{
if($account_type=='checking')
{
#query for sql to look up account
$balance=100;
}
elseif($account_type=='savings')
{
#query for sql to look up account
$balance=25;
}
return $balance;
}
function verify_account($account_type)
{
if($account_type=="checking" || $account_type=="savings")
{
#account verified
return $account_type;
}
else
{
echo $account_type." is not a valid account";
exit();
}
}
function deposit($account_type, $amount)
{
$cur_bal=$this->get_bal($account_type);
$new_bal=$cur_bal+$amount;
print "Balance for “.$account_type.” is $”.$new_bal.”
“;
}
}
//create new class instance
$transaction=new account_transact();
//checking deposit
$account=$transaction->verify_account(”checking”);
$transaction->deposit($account,”5″);
//savings
$account=$transaction->verify_account(”savings”);
$transaction->deposit($account,”-10″);
?>

Today i found a better way to kill processes in linux. Use pkill. Now instead of killing items w/ the process id, you can kill items matching a certain pattern, plus lots of extras…
For example, lets say i have a bunch of stagnate processes all spawned from the same script.
root 27623 27622 0 Jun25 ? 00:00:00 /bin/sh -c python /etc/nagios2/scripts/notify_failover.py
root 27625 27623 0 Jun25 ? 00:00:00 python /etc/nagios2/scripts/notify_failover.py
root 27920 27919 0 Jun25 ? 00:00:00 /bin/sh -c python /etc/nagios2/scripts/notify_failover.py
root 27922 27920 0 Jun25 ? 00:00:00 python /etc/nagios2/scripts/notify_failover.py
root 28206 28205 0 Jun25 ? 00:00:00 /bin/sh -c python /etc/nagios2/scripts/notify_failover.py
root 28208 28206 0 Jun25 ? 00:00:00 python /etc/nagios2/scripts/notify_failover.py
root 28730 28729 0 Jun25 ? 00:00:00 /bin/sh -c python /etc/nagios2/scripts/notify_failover.py
root 28732 28730 0 Jun25 ? 00:00:00 python /etc/nagios2/scripts/notify_failover.py
root 29061 29060 0 Jun25 ? 00:00:00 /bin/sh -c python /etc/nagios2/scripts/notify_failover.py
Now, I could kill them by doing this….
kill 27623 27625, etc, etc…
However, the more efficient way to do this would be to do the following…
pkill -f “python /etc/nagios2/scripts/notify_failover.py”
Whamo! All process gone!

Symmetrical difference calculates the difference of not whats in the just one list. It calculates the items that are not common in both lists!
list1=['donkey','balls']
list2=['donkey','scrotom']
set1=set(list1)
set2=set(list2)
print set1
set(['donkey', 'balls'])
print set2
set(['donkey', 'scrotom'])
symdiff = set1 ^ set2
symdiff
set(['balls', 'scrotom'])

There is no way to do a function diff on a list. However you can do a loop.
list1 = [1, 2, 3, 5, 7, 11]
list2 = [1, 2, 4, 8, 16, 32]
diff_list = []
for item in list1:
if item not in list2:
diff_list.append(item)
print diff_list
[3, 5, 7, 11]
Or use sets….
from sets import Set
set1=Set(['a','b','c'])
set2=Set(['d','b','c'])
diff=set1-set2
print diff
Set(['a'])
for x in diff:
print x
a
Or conver list to a set…
list1=['a','b']
list2=['b','c']
set1=set(list1)
set2=set(list2)
diff=set1-set2
