[PHP] Debug/Learn Recursion of an Object
I am a bit new to Objects and Recursion
Any push in the right direction is appreciated
Generated from Pear's mimedecode, I have an object whose print_r is:
http://www.siren.cc/dev/object.txt
The function below will correctly traverse the object and find the
'correct' node.
Unfortunately, it is a little beyond my understanding at present. :(
Is there a way to debug the below function to echo how it is
traversing the object ?
For example, how would I echo the key names and values while it is
traversing ?
The hope is that something will click and I'll finally wrap my brain
around this
many thanks
function getBody($part, $primary = 'text', $secondary = 'plain')
{
$body = false;
if (is_array($part)) {
foreach($part as $subpart) {
if (! $body = getBody($subpart, $primary, $secondary)) {
continue;
} else {
return $body;
}
}
} else {
if (isset($part-parts)) {
return getBody($part-parts, $primary, $secondary);
} else {
if ($part-ctype_primary == $primary $part-ctype_secondary ==
$secondary) {
return($part-body);
}
}
}
return $body;
}

I got it :) just put a print_r at each step of the function like: print_r($part-$parts); thanks g On May 18, 2006, at 11:59 AM, Robert Cummings wrote: On Thu, 2006-05-18 at 14:11, Graham Anderson wrote: I am a bit new to Objects and Recursion Any push in the right direction is appreciated Generated from Pear's mimedecode, I have an object whose print_r is: http://www.siren.cc/dev/object.txt The function below will correctly traverse the object and find the 'correct' node.
