RE: [PHP] Creating a variable name using a variable From: Adam Warner (iconsult <email protected>)

Thanks Daniel, Matt and Kathleen,

My message only appeared to arrive to the list a couple of hours ago even
though I had received two replies by then!

So far with PHP I am fondly reminded of a Homer (Simpson) quotation:
"Is there anything a doughnut cannot do?"

Many thanks,
Adam Warner

Use a variable variable

$i = 2;
$url = "url$i";

$$url will then refer to $url2 (note the 2 $$'s)

Cheers

Subject: [PHP] Creating a variable name using a variable

Hi all,

I'm new to the list. Hopefully this is not too frequently asked...

Now I realise I should probably be using an array. But it would be nice to
occasionally create a variable name from a variable.

For example:
I have 3 variables $url1, $url2 and $url3.

I have another variable $i (which takes one of the values 1, 2 or 3).

If $i=2 is there any way I can refer to $url2 using by combining "$url" and
$i?

Many thanks,
Adam

PS: To the developers of PHP many thanks. PHP is awesomely fun and powerful.
