What are the potential performance issues with using SQL queries for every word in a text for generating links in a PHP application?

Using SQL queries for every word in a text to generate links in a PHP application can lead to performance issues due to the high number of queries being executed. To solve this problem, you can use a more efficient approach such as caching the results of the queries or using a full-text search engine like Elasticsearch. 

// Example of caching the results of SQL queries for generating links
$words = explode(' ', $text);

foreach ($words as $word) {
    $link = getLinkFromCache($word);
    
    if (!$link) {
        $link = getLinkFromDatabase($word);
        saveLinkToCache($word, $link);
    }
    
    echo "<a href='$link'>$word</a> ";
}

function getLinkFromCache($word) {
    // Implementation of fetching link from cache
}

function getLinkFromDatabase($word) {
    // Implementation of fetching link from database
}

function saveLinkToCache($word, $link) {
    // Implementation of saving link to cache
}
