I guess I do not understand. The following example works just fine in PHP
4.1.0RC1:
test.php
=====
<?php
include 'testlib.php';
include 'testlib.php';
test();
?>
testlib.php
======
<?php
if (!defined('_TESTLIB_PHP')) {
define ('_TESTLIB_PHP', 1);
function test() {
print "Function test()\n";
}
}
?>
This however does not work and IMHO should not work. (It did work on PHP
4.0.6)
testlib.php
======
<?php
if (!defined('_TESTLIB_PHP')) {
define ('_TESTLIB_PHP', 1);
return;
}
function test() {
print "Function test()\n";
}
?>
The second example utilises the fact that the script compiling stoped at
return, while now it does not. I really fail to see what's wrong with using
the first example and how that cannot be used for preventing multiple
function definitions.
