I mean when i can use var_dump() and mage::log().
I have some idea about log. if we enable log settings and for example if we use mage::log($obj).it will print $obj information in system.log file.
where as var_dump() print direclty in browser.
Please comment if i'm anything wrong.

var_dump()
shows the information in your browser.Mage::log()
echos information to your system.log file (var/log/system.log
).To use
Mage::log()
, you need to enable logging in the backend: System > Configuration > Developer -> Log Settings -> Enabled > Set to "Yes".Furthermore you can force logging using the forth parameter of
Mage::log()
set to true:Mage::log($foo,null,'system.log',true);
According to the function in Mage.php:
public static function log($message, $level = null, $file = '', $forceLog = false)
Mage::log()
will be especially useful if you do not see the output in your browser (debugging SOAP API requests, AJAX requests,...).
