RE: [PHP] Nesting 'foreach ()'

thanks, I found that there is a bug. The curly braces don't make any difference in fact ... foreach ($fred as $fred1) foreach ($fred as $fred2) echo "$fred1 : $fred2<br>"; is okay (but still doesn't work) although I have noticed that you seem to need to code-block single statements in if ... else constructs i.e if (1==1) echo("fred") else echo("bill"): should work but doesn't. Another bug?.
