What are the typical issues encountered when trying to run PHP scripts on a web server?

One common issue when running PHP scripts on a web server is the presence of syntax errors in the code. These errors can prevent the script from executing properly. To solve this issue, carefully review the code for any syntax errors and correct them accordingly.

// Example of correcting syntax errors in PHP code
<?php
    $variable = "Hello, World!";
    echo $variable;
?>
