foreach() has many functions, looping over arrays, objects and implementing the iterator interface. I think it's also quite intuitive to use foreach() for strings, too.
If you want to implement a parser in PHP, you have to go the way with for + strlen + substr() or $x[$i] to address one character of the string. We could overdo the functionality of foreach() by implementing LVAL's, too, in order to access single bits but this is really uncommon, even if the way of thinking could be, that foreach() gives a single attribute of each value, no matter if it's a complex object with the iterator interface or a primitive. What do you think about this one? My point of view is, that foreach() is very useful, which was acknowledged by many ppl via the comments of my article. I think, adding features like this persuades the one or the other PHP user to upgrade to 5.4. Robert
