ID: 16738 Comment by: jharders at tricept dot de Reported By: benh at uk2 dot net Status: Closed Bug Type: Documentation problem Operating System: n/a PHP Version: 4.2.0 Assigned To: alindeman New Comment: I've downloaded the latest PHP5-win-binary-package, assuming that bug will would fixed, but it is'nt? Previous Comments: ------------------------------------------------------------------------ [2002-04-22 18:47:43] bs@php.net This bug has been fixed in CVS. ------------------------------------------------------------------------ [2002-04-22 17:21:41] alindeman@php.net assigned to myself ------------------------------------------------------------------------ [2002-04-22 16:59:24] benh at uk2 dot net <?php $foo = 'Bob'; // Assign the value 'Bob' to $foo $bar = &$foo; // Reference $foo via $bar. $bar = "My name is $bar"; // Alter $bar... echo $foo; // $foo is altered too. echo $bar; ?> Why do '$bar = "My name is $bar";'? And then do 'echo $foo' *before* you 'echo $bar'? The point you're trying to make is surely expressed better like this: <?php $foo = 'Bob'; // Assign the value 'Bob' to $foo $bar = &$foo; // Reference $foo via $bar. $bar = "Dave"; // Alter $bar... echo $bar; echo $foo; // $foo is altered too. ?> Clearer for the newcomer to programming, ne? ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16738&edit=1
