[TYPO3] EXT programming question

[Benjamin Mack]

Hey,

this is a typical PHP expression and has nothing to do with TYPO3. With

   $content = 'My Text';

you always set the $content variable again and override the value stored 
before in the variable. With

   $content .= 'My Text';

which is a shortcut for:

   $content = $content . 'My Text';

you set the variable with the old content AND the appending text.

greetings,
benni.
