What are common mistakes or oversights that can lead to PHP scripts not displaying output properly?

One common mistake that can lead to PHP scripts not displaying output properly is forgetting to include the `echo` or `print` statement to actually output content. Another oversight is not properly closing PHP tags or using incorrect syntax, which can prevent the script from executing correctly. To solve this issue, always make sure to include an `echo` or `print` statement to display output and double-check the syntax and proper closing of PHP tags. 

<?php
// Incorrect way without echo or print statement
$variable = "Hello World";
// Correct way with echo statement
echo $variable;
?>
