How can PHP code be optimized to prevent automated spam posts targeting specific keywords?

To prevent automated spam posts targeting specific keywords in PHP, you can implement a filtering mechanism that checks the content of the post for any blacklisted keywords. You can create an array of keywords to check against and then use a function to scan the post content for these keywords. If any of the keywords are found, you can reject the post or take appropriate action. 

// Array of blacklisted keywords
$blacklistedKeywords = array("spam", "viagra", "casino");

// Function to check for blacklisted keywords in post content
function checkForBlacklistedKeywords($postContent, $blacklistedKeywords) {
    foreach ($blacklistedKeywords as $keyword) {
        if (stripos($postContent, $keyword) !== false) {
            // Keyword found, take action like rejecting the post
            return true;
        }
    }
    return false;
}

// Example usage
$postContent = $_POST['content'];
if (checkForBlacklistedKeywords($postContent, $blacklistedKeywords)) {
    // Reject the post or take appropriate action
    echo "Post contains blacklisted keywords, please revise.";
} else {
    // Post is clean, proceed with processing
    echo "Post is clean and can be submitted.";
}
