[Resolved] Appending a var with a number

In a MySQL table, certain fields are named blah1, blah2, bla3,.... Now after fetching these values in PHP, I want to print them. Instead of doing

echo "$blah1<br>$blah2<br>$blah3<br>...";

I would like to use a for loop. How do I append the variable with a number? The following doesn't work:

for ($i=0; $i < n; $i++) { 
echo "$blah[$i]<br>";
}

Thanks

The brackets indicate you are supplying an index of an array. Obviously, this is not so.

If you want PHP to actually perform logic on a variable name, you can use curly brackets ( {} ) to indicate this, like so:

for ($i=0; $i < 5; $i++) echo ${'blah'.$i} . '<br>';

Please note 2 things:

I changed 'n' to a number; I assumed this is what you meant, but just wanted to make sure.
This for() structure will start with $blah0 and echo untill $blah4. If you wanted to start at $blah1, make sure you change the '$i=0;' to '$i=1;' !

Thanks bradgrafelman.
That's exactly what I needed to know.
