How to type in arabic chat slang?

[suzie]

I want to speak to my cousin in arabic on facebook, but she types in this way that they use numbers. Like 7 = ha. She taught me but I forgot. And when I talk to her, do I just speak to her like "Izayik?" (how are you?) but with the numbers? so like 'welcome' would be "A7lan" (ahlan)?

Edit: this is in the category 'ramadan' because i want most people who answer to know how to speak arabic or are from countries like egypt so they understand.

7= ha
3= a'an (3en) ?
6 =ta/da ?
8= g'en (8en) ?
2= eh
5=kha
9= sod ?
i wish i can help you but im not really good in egyption arabic

3 = 'ayn
3' = ghayn
7 = the ha that looks like jim without the dot
7' = kha
or 5 is kha too
2 = like qaf, but pronounced as a hamza.

7= ha
9= ka for example '' 9oultou''
3= its like ha but much stronger " 3adim"
2= aa for example their is a name caled aala istead of wrighting it with double aa they would use 2.

thats all their is. The 9 3 2 are quite hard to explain for their are no letter to explain them with...
