Bug #16738 Updated: confusing explanation of assigning by reference

ID: 16738 Updated by: alindeman@php.net Reported By: benh@uk2.net -Status: Open +Status: Assigned Bug Type: Documentation problem Operating System: n/a PHP Version: 4.2.0 -Assigned To: +Assigned To: alindeman New Comment: assigned to myself Previous Comments: ------------------------------------------------------------------------ [2002-04-22 16:59:24] benh@uk2.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
