What are common syntactic errors in PHP code that can prevent a simple website from functioning properly?

One common syntactic error in PHP code that can prevent a simple website from functioning properly is missing semicolons at the end of statements. Semicolons are used to indicate the end of a statement in PHP, so omitting them can lead to syntax errors. To fix this issue, simply ensure that each statement in your PHP code is followed by a semicolon. Example:

// Incorrect code without semicolons
<?php
    $message = "Hello, world"
    echo $message
?>

// Corrected code with semicolons
<?php
    $message = "Hello, world";
    echo $message;
?>
