What is causing the issue of a tabulator appearing in the textarea in the PHP code provided?

The issue of a tabulator appearing in the textarea in the PHP code provided is likely caused by the use of the PHP heredoc syntax, which preserves formatting including tabs and spaces. To solve this issue, you can use the nowdoc syntax instead, which does not interpret variables or special characters. 

// Original code with heredoc syntax causing tabulator to appear
$message = <<<EOT
    This is a message with a tabulator.
EOT;

// Updated code using nowdoc syntax to avoid tabulator appearing
$message = <<<'EOT'
    This is a message without a tabulator.
EOT;
