我的代码显示了同一个表中数据的最后5个查询顺序是这个......

$sql = "SELECT id, titlu, link, poza, alt FROM istorie WHERE approved='1' ORDER BY RAND() LIMIT 3";
$query = mysqli_query($db_conx, $sql);
$istorielist = '';
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
    $id = $row["id"];
    $titlu = $row["titlu"];
    $link = $row["link"];
    $poza = $row["poza"];
    $alt = $row["alt"];
    $istorielist .= '<div id="articol-content-more"><a href="/istorie/'.$link.'"><img src="/images/'.$poza.'.jpg"class="articol-content-more-image" alt="'.$alt.'"><p class="articol-content-more-title">'.$titlu.'</p></a><span><a class="articol-content-more-afla" href="/istorie/'.$link.'">Citește mai multe</a></span><span class="articol-content-more-fl"><div class="fb-share-button" data-layout="button_count" data-href="http://esticurios.ro/istorie/'.$link.'"></div></span></div>';

您可以将类别数组静态或将所有类别放入一个表中，并动态生成类别数组

<?
$catArray = array("history","nature", "lifestyle", "science","travel");    
$istorielist = '';
foreach($catArray as $k=>$v)
{    
    $sql = "SELECT id, titlu, link, poza, alt FROM ".$v." WHERE approved='1' ORDER BY RAND() LIMIT 3";
    $query = mysqli_query($db_conx, $sql);   
    while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
        $id = $row["id"];
        $titlu = $row["titlu"];
        $link = $row["link"];
        $poza = $row["poza"];
        $alt = $row["alt"];
        $istorielist .= '<div id="articol-content-more"><a href="/istorie/'.$link.'"><img src="/images/'.$poza.'.jpg"class="articol-content-more-image" alt="'.$alt.'"><p class="articol-content-more-title">'.$titlu.'</p></a><span><a class="articol-content-more-afla" href="/istorie/'.$link.'">Citește mai multe</a></span><span class="articol-content-more-fl"><div class="fb-share-button" data-layout="button_count" data-href="http://esticurios.ro/istorie/'.$link.'"></div></span></div>';
    } 
}
