How can reserved words in SQL syntax impact the functionality of PHP scripts?

Reserved words in SQL syntax can impact the functionality of PHP scripts by causing syntax errors when these words are used as column names, table names, or aliases in SQL queries. To solve this issue, it is recommended to enclose the reserved words in backticks (`) in SQL queries to avoid conflicts with the SQL syntax. This ensures that the SQL engine interprets the reserved words as identifiers rather than keywords. 

<?php
// Example SQL query using reserved word as a column name
$columnName = "select";
$query = "SELECT `$columnName` FROM table_name";
// Execute the query
$result = mysqli_query($connection, $query);
?>
