What are common errors or pitfalls when using the <<<EOT syntax in PHP, and how can they be avoided?

One common error when using the <<<EOT syntax in PHP is not properly closing the heredoc block with the specified delimiter (EOT in this case). This can lead to syntax errors or unexpected behavior in your code. To avoid this, always make sure to close the heredoc block with the correct delimiter at the beginning of a new line.

// Incorrect usage of <<<EOT syntax
$message = <<<EOT
This is a heredoc string
EOT; // Missing new line before the delimiter

// Corrected code
$message = <<<EOT
This is a heredoc string
EOT
