How to use for each statement in Php?

I have here an example using foreach statement in Php the first thing you need to do
is to open notepad but if you have dream weaver or other software editor is OK.
Php has several conditional and loop statements that have been part of the

used foreach for years. For example java. Unlike the other conditional and loop
statements, the foreach statement is used only on arrays so basically foreach statement
accept only variable arrays. I have here an example that you can download using foreach statement.. You can post comments or question about other entities in Php or other languages.
