One thing to note is that constants are not looked for
within strings. So:
// This is okay but can cause confusion. No errors
// are created but many prefer not to do this.
$str = "Hello $there[friend], how are you?";
Outside of a string, $there[friend] will indeed seek
a constant nam

Thats correct, php will think they are constants and
Hi,
I would suggest not to use $hash[var1][var2] instead of
$hash['var1']['var2'] because afaik php will think u mean two constants (
var1 and var2 ).
Just if it doesnt find these constants it will use them as
$hash['var1']['var2'].

Not really sure but str has to be $str, and I usually do print lines like
this
$str = "I can NOT use ".$hash['vars']." in strings";
the . will concat the strings together.
Hope this helps,

Try this one:
str = "I can NOT use ".$hash['vars']." in strings";

Hi,
I think this will accomplish what your trying to achieve.
$str = "I can use $hash[vars] in strings";
However, this will not work for multi dimensional arrays... eg:
$hash['var']['var2'] = "Elephant";
$str = "I can NOT use $hash[var][var2] in strings";
will output "I can NOT use Array[v
I don't know the answer to why, but you can do this:
$str = "I can use ".$hash['vars']." in strings";
