What steps can be taken to troubleshoot and resolve SQL syntax errors in PHP when using MySQL and Access databases?

To troubleshoot and resolve SQL syntax errors in PHP when using MySQL and Access databases, you can start by carefully reviewing your SQL query for any syntax mistakes such as missing commas, incorrect table or column names, or improper use of quotation marks. Additionally, you can use error handling functions in PHP to catch and display any SQL errors that may occur during query execution.

// Example code snippet for error handling in PHP with MySQL database
$conn = mysqli_connect("localhost", "username", "password", "database");

if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($conn, $sql);

if (!$result) {
    die("Error executing query: " . mysqli_error($conn));
}

// Process the query result here
