Hey John,
Actually, you don't seem to far off. You can use a string as a variable name
by enclosing the string in ${ }.
i.e: ${"foo"}
You should be able to write your loop as something like:
foreach($item as $value) {
// do some stuff
foreach(${"prefix${value}suffix"} as $v) {
// do some stuff
}
}
All of the normal string and variable rules apply, so you can do things like:
echo ${ "some" . $bar ."text"};
${"prefix${baz}suffix"} = 100000;
${md5($quux)) = $quux;
There is also the added behavior (benefit?) of being able to use odd values
for variable names:
echo ${" \n\t"} = "Holy Whitespace, Batman!";
HTH!
