please have a look at the manual page at
http://php.net/empty
"empty -- Determine whether a variable is set"
empty() does only accept variables as argument.
not general expressions

The following script generates a parse error on line 8 (Parse error: parse error, expecting
`')'' in /home/dbellizzi/cvs/crm/htdocs/test.php on line 8
<?php
class Foo {
function blah(){
return "abcd";
}
}
$foo = new Foo();
if (empty($foo->blah())){
echo("foo->blah is empty");
}
?>
However, when changed to this script that assigns the variable before checking it with empty(), it
works fine:
<?php
class Foo {
function blah(){
return "blah";
}
}
$foo = new Foo();
$blah = $foo->blah();
if (empty($blah)){
echo("foo->blah is empty");
}
?>
I have duplicated this on a few different machines, but if you need information on my setup,
libraries, etc. please email me and I'd be happy to provide more information
