Question

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张图像。但是问题是每张幻灯片的while循环中文本重复。

示例：

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
----------                                        ----------------

这是问题所在：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

如果您只想打印一次文本，则创建一个变量来存储信息，无论该信息是否已打印。另外包装通过条件语句打印信息的代码（如果有的话...），然后检查条件是否满足（在您的情况下，如果信息未打印），并且如果条件得到满足，则信息将被打印，否则不是。

查看已添加评论并按如下所示修改代码
