What are the potential reasons for the entire text being outputted only at the end of a PHP script execution?

The potential reasons for the entire text being outputted only at the end of a PHP script execution could be due to output buffering being enabled. To solve this issue, you can turn off output buffering using the `ob_end_flush()` function at the beginning of the script. 

<?php
ob_end_flush(); // Turn off output buffering

// Your PHP script code here
echo "Hello World!";
?>
