Zend::dump() prints and/or returns information about an expression. It is a wrapper
for the PHP function var_dump(). It
wraps the output with (X)HTML <pre> tags and optionally prepends a label.
<?php dump($var, $label=null, $echo=true) ?>
The $var argument specifies the expression or variable for which the information
will be obtained.
The $label is any arbitrary text to be prepended to the output of
Zend::dump(). This is useful when dumping many variables on a single screen.
The boolean $echo controls whether the output of Zend::dump() is echoed
or not. If TRUE, the output will be echoed. Regardless of the state of
$echo, the output is always be returned.
