; in PHP


What is the semi colon used for in PHP?


I will quote php.net because that is the best answer possible. It's simple and explains enough.

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement. The closing tag of a block of PHP code automatically implies a semicolon; you do not need to have a semicolon terminating the last line of a PHP block. The closing tag for the block will include the immediately trailing newline if one is present.
