Dude,
The below is a bad, needlessly confusing example for a reference aimed at beginners.
<?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.
?>
Sure, the previous example is equivalent, but why not make the point as simply as possible? Your
documentation should target the 13-year-old shepherd boy in Iraq who's learnt English from MRE
wrappers as well as the 29-year-old MIT geek.
