What is the significance of using @ before function calls in PHP scripts to prevent header modification errors?

When using the @ symbol before a function call in PHP scripts, it suppresses any errors or warnings that may occur during the execution of that function. This can be particularly useful when trying to prevent header modification errors, which can occur if headers have already been sent to the browser before calling functions like header(). By using the @ symbol, you can prevent these errors from interrupting the script's execution. 

<?php
// Suppress errors with @ symbol
@header('Content-Type: text/html');

// Rest of the code here
?>
