Check if value in array is unique, and change all duplicates if not

[johnsmith153]

I need to CREATE unique values for all matching arrays,

 

so, if I start with:

 

$array[0]="Jim Smith";

$array[1]="Dave Brown";

$array[2]="Dennis Brown";

$array[3]="Steve Smith";

 

I need to return the surname, but if not unique, I need to append the first letter of name, then keep checking to ensure unique

 

So I would then end with:

 

$array[0]="J.Smith";

$array[1]="Da.Brown";

$array[2]="De.Brown";

$array[3]="S.Smith";

 

Any ideas?

You'll have to write a function that does this.
