What are the potential pitfalls of using the "LOAD DATA LOCAL INFILE" command in PHP when accessing external files?

Using the "LOAD DATA LOCAL INFILE" command in PHP to access external files can pose a security risk as it allows for the execution of arbitrary SQL commands. To mitigate this risk, it is recommended to sanitize user input and validate the file path before using it in the command. 

// Sanitize and validate the file path before using it in the query
$file_path = $_POST['file_path'];
if (filter_var($file_path, FILTER_VALIDATE_URL)) {
    $query = "LOAD DATA LOCAL INFILE '" . $file_path . "' INTO TABLE table_name";
    // Execute the query
}
