I don't have a complete example, however, if you already have code that can use PHP and sendAndLoad to load a single string variable, you're nearly there.

To load a string variable, you might send something like

str=xxxxxxxxx

If you put the array elements in the string, separated by a delimiter, such as '.'

str=xxx.xxx.xxx.xxx.xxxx

You can then, in actionscript, split this up into an array.

ary = str.split('.');
