array value as array index

[Nick Wedd]

This code
$cn = $ct[$k];
print "<a name='$ct[$k]'>$continentnam e[$cn]</a>\n";
works, and prints something like <a name='af'>Afric a</a>

But if I try to simplify it, to
print "<a name='$ct[$k]'>$continentnam e[$ct[$k]]</a>\n";
I get a syntax error
unexpected '[', expecting ']'

So what is the correct way to write something like $a[$b[$c]] ? I have
tried adding extra {} and '' here and there, so far without success.

Curly braces should work. Tried & tested:
<?php
$bar = 'bar';
$foo[$bar] = 'baz';
$foz['baz'] = 'success';
echo "{$foz[$foo[$bar]]}";
?>

So use print "<a name='$ct[$k]'>{$continentna me[$ct[$k]]}</a>\n";

Or concatenation
print "<a name='$ct[$k]'>".$continentn ame[$ct[$k]]."</a>\n";

Thanks to both of you.

I am impressed by how positive and helpful the responses in this
newsgroup are.
