Short answer, no.

Variables are treated as strings by default.  It is not necessary to
define them
in advance.  You can test values for whatever type you want, and PHP
will handle
values however you want.

For example:

$var=1;
$anothervar=2;

$myvar = $var + $anothervar;
// myvar will be 3;  because this is math (+), it assumes numbers

$myvar = $var . $anothervar;
$myvar will be "12";  // because this is concantenation (.), it assumes
characters,
// So, this is the string "1" with the string "2" appended.

kind regards,

bill
