我做了一个简单的演示，并从 mysql 获取文本和图像。例如，我有一个文本和 5 个图像。每张幻灯片必须有 2 张图片。但问题是每张幻灯片上的 while 循环中的文本都重复。

例子：

This is how it works now:                         I want this:
-----------                                       ----------------
Slide1                                            Slide1
text 1                                            text 1
2 images                                          2 images
-----------                                       ----------------
-----------                                       ----------------
Slide2                                            Slide2
text 1                                        
2 images                                          2 images
-----------                                       ----------------
-----------                                       ----------------
Slide3                                            Slide3
text2        
1 image                                           1 image
----------                                        ----------------

这就是问题所在： 在此处输入图像描述 我想从第二张和第三张幻灯片中删除重复的文本。这是我的代码

$brojacslikapostrani = 0;
$query1 = "SELECT izvestaji.operacija, izvestaji.ucinak, izvestaji.id, operacije.nazivEng FROM izvestaji INNER JOIN operacije ON izvestaji.operacijaId=operacije.id WHERE izvestaji.datum='$datum' AND izvestaji.projekatId='$projekatId'";
$result1 = mysqli_query($con, $query1);
while ($row = mysqli_fetch_array($result1)) {           

            $id = $row['id'];

            $query2 = "SELECT img_name FROM slike WHERE izvestajId='$id' AND datum='$datum'";
            $result2 = mysqli_query($con, $query2);

            while ($row2 = mysqli_fetch_array($result2)) {

如果您只想打印一次文本，则创建存储信息的变量，无论信息是否已打印。另外包装通过条件语句打印信息的代码（如果有什么......），然后检查是否满足条件（在您的情况下，如果信息未打印），如果满足条件，则将打印信息，否则不是。

请参阅评论添加并修改代码如下

<?
$brojacslikapostrani = 0;
$query1 = "SELECT izvestaji.operacija, izvestaji.ucinak, izvestaji.id, operacije.nazivEng FROM izvestaji INNER JOIN operacije ON izvestaji.operacijaId=operacije.id WHERE izvestaji.datum='$datum' AND izvestaji.projekatId='$projekatId'";
$result1 = mysqli_query($con, $query1);
while ($row = mysqli_fetch_array($result1)) {           

            $id = $row['id'];

            $query2 = "SELECT img_name FROM slike WHERE izvestajId='$id' AND datum='$datum'";
            $result2 = mysqli_query($con, $query2);

            $textPrinted = false; #<= ADDED
            while ($row2 = mysqli_fetch_array($result2)) {

                if ($brojacslikapostrani % 2 == 0) {
                    $currentSlide = createTemplatedSlide($objPHPPresentation);

                    $currentSlide->setBackground($oBkgImage);
