Another warning in response to the previous note:
> just a warning as it appears that an empty value is not
a scalar.
That statement is wrong--or, at least, has been fixed with a
later revision than the one tested. The following code
generated the following output on PHP 4.3.9.
CODE:
<?php
echo('is_scalar() test:'.EOL);
echo("NULL: " . print_R(is_scalar(NULL),
true) . EOL);
echo("false: " . print_R(is_scalar(false),
true) . EOL);
echo("(empty): " . print_R(is_scalar(''),
true) . EOL);
echo("0: " . print_R(is_scalar(0),
true) . EOL);
echo("'0': " . print_R(is_scalar('0'),
true) . EOL);
?>
OUTPUT:
is_scalar() test:
NULL:
false: 1
(empty): 1
0: 1
'0': 1
THUS:
* NULL is NOT a scalar
* false, (empty string), 0, and "0" ARE
scalars
