[TYPO3-english] qustion about cObject

[tom]

Hi,

In  typo3conf/ext/tmplselect/pi1/class.tx_tmplselect_pi1.php,
...
function main($content,$conf)
{
...
}

I put var_dump($content); it shows:

string '' *(length=0)*

string '' *(length=0)*

string '' *(length=0)*

I put var_dump($content); it shows:

*array*
  'includeLibs' => string
'typo3conf/ext/tmplselect/pi1/class.tx_tmplselect_pi1.php'
*(length=56)*
  'userFunc' => string 'tx_tmplselect_pi1->main' *(length=23)*

*array*
  'includeLibs' => string
'typo3conf/ext/tmplselect/pi1/class.tx_tmplselect_pi1.php'
*(length=56)*
  'userFunc' => string 'tx_tmplselect_pi1->main' *(length=23)*

*array*
  'includeLibs' => string
'typo3conf/ext/tmplselect/pi1/class.tx_tmplselect_pi1.php'
*(length=56)*
  'userFunc' => string 'tx_tmplselect_pi1->main' *(length=23)*
  'defaultTemplateFileName' => string 'ct_1.html' *(length=9)*
  'templateType' => string 'sub' *(length=3)*

My question is:

1. what does $content,$conf mean?

2. How could I know the value of $content,$conf?

Thanks.
