There are several ways of declaring variabeles. (Sort of like the Dim instruction in vb or asp)
settype($myvar, "string");
(http://be2.php.net/settype)
or
$myvar = (string) "Hello";
Or let php do the hard work for you,
$myvar = "Hello";
It should normally produce the same result...
NOTE:
$myvar = 1; is not the same as $myvar = "1";
Whereas the first would count as an integer, the second as a string. Altough php see trough these
things, a database query would not. For example:
odbc_query("INSERT INTO table (number) VALUES(' ".$myvar." ')"); WILL
NOT work,
odbc_query("INSERT INTO table (number) VALUES (".$myvar.")"); WOULD work.
