Using a variable in a variable name?

[VestanPance]

So I am creating a loop and I want to use the looped variable in the varaible name...like so:

	 ///// Times /////
	 echo "<label>Times:</label>";
			$i=1;
			while ($i < 7) {

		echo "<div class='textfield'>$event_time_$i</div><br/>";
		$i++;
		}

Any ideas? I keep getting errors.

Thanks! SP.

You have to concatenate them together.

echo "<div class='textfield'>$event_time_.$i</div><br/>";

Thanks for the input. However, I already tried that and get this error seven times:

Notice: Undefined variable: event_time_ in C:\Apache2\htdocs\www.imagodeiministry.com\main\event.php on line 51
.1

Any other ideas?

Well, my guess is that your variable is actually called $event_time and not $event_time_
Only a guess, since you don't post the code where the $event_time variable is created...

So, I'm guess you want to concatenate $event_time with $i, using an underscore as the tie...

OK, then your line should look like this:

echo "<div class='textfield'>$event_time."_".$i</div><br/>";

Good idea but now I get this:

Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in C:\Apache2\htdocs\www.imagodeiministry.com\main\event.php on line 51

Isn't it a problem to have so many double quotes in there?

I have 7 fields being pulled from a database and assigned the variable names: $date_time_1, $date_time_2, ... So I wanted to print them through the loop without having to list them all individually.

Instead of dumping them out to individual variables, dump them into an array...

Then you can pull them out of the array by their index values using your loop...

[VestanPance]

Great. That works. Thanks for the help.

[TheDefender]

No problem... Sorry about the confusion there, but the arrays are the better option almost 99.999% of the time in this type of instance...

Good to know. Thanks again.
