The ${x_$n} "trick" doesn't work for me on PHP 3.0.9 (RedHat RPMs). Neither did
${x_${n}}.
<br>
I kept getting errors like Parse error: parse error, expecting
'['' or
PHP_CLASS_OPERATOR' or `'}'' in filename on line xxxx.
<br>
I worked around it using a temporary variable.
ie. $tmpvar = "x_$n"; and then I used ${$tmpvar}. It works, buit it's not as
convenient.
Is this fixed in newer versions perhaps?
