仅在指定条件下执行php和html

So I have this piece of code that I am trying to work with. What I would like to do is to run the code only when $formname == 4 and when it's not, I don't want the code to run. I tried using an if statement on the whole block of code but for some reason that did not work for me. I'm also pretty sure that there is a better way to write this code since all of my if statements have the same condition, so any suggestions on condensing the code would be greatly appreciated. I am fairly new to programming so pardon my lack of knowledge, and thanks in advance for any help.

<div class="tabcontent2" id="tab_content_<?php echo $a; ?>" <?php if($formname == 4 AND $formID == null){ echo "style='display:none'" ;} ?>>
    <div class="tabs-content3">
        <?php 
            include 'Subpages/overview.php';  
    </div>
</div>

<?php $a++; ?>
<div class="tabcontent2" id="tab_content_<?php echo $a; ?>" <?php if($formname == 4 AND $formID == null){ echo "style='display:none'" ;} ?>>
    <div class="tabs-content3">
        <?php 
            include 'Subpages/abroad.php'; 
        ?>
    </div>
</div>

<?php $a++;?>
<div class="tabcontent2" id="tab_content_<?php echo $a; ?>" <?php if($formname == 4 AND $formID == null){ echo "style='display:none'" ;} ?> >
    <div class="tabs-content3">
        <?php 
            include 'Subpages/safety.php';  
        ?>
    </div>
</div>

<?php $a++; ?>
<div class="tabcontent2" id="tab_content_<?php echo $a; ?>" <?php if($formname == 4 AND $formID == null){ echo "style='display:block'" ;} ?>>
    <div class="tabs-content3">
        <?php 
            include 'Subpages/faqs.php';  
        ?>
    </div>
</div>

所以我有这段代码,我正在尝试使用它。 我想要做的是仅在 $ formname == 4 时运行代码,当它不是时,我不希望代码运行。 我尝试在整个代码块上使用 if语句但由于某些原因对我不起作用。 我也很确定有更好的方法来编写这段代码,因为我的所有 if语句具有相同的条件,因此任何关于压缩代码的建议都将非常感激。 我对编程很新,所以原谅我缺乏知识,并提前感谢任何帮助。

 &lt; div class =“tabcontent2”id =“tab_content_&lt;?php  echo $ a;?&gt;“  &lt;?php if($ formname == 4 AND $ formID == null){echo“style ='display:none'”;}?&gt;&gt; 
&lt; div class =“tabs-content3”&gt;  
&lt;?php 
包含'Subpages / overview.php';  
&lt; / div&gt; 
&lt; / div&gt; 
 
&lt;?php $ a ++;  ?&gt; 
&lt; div class =“tabcontent2”id =“tab_content_&lt;?php echo $ a;?&gt;”  &lt;?php if($ formname == 4 AND $ formID == null){echo“style ='display:none'”;}?&gt;&gt; 
&lt; div class =“tabs-content3”&gt;  
&lt;?php 
包括'Subpages / abroad.php';  
?&gt; 
&lt; / div&gt; 
&lt; / div&gt; 
 
&lt;?php $ a ++;?&gt; 
&lt; div class =“tabcontent2”id =“tab_content_&lt;?php echo $ a  ;?&gt;“  &lt;?php if($ formname == 4 AND $ formID == null){echo“style ='display:none'”;}?&gt;  &gt; 
&lt; div class =“tabs-content3”&gt; 
&lt;?php 
 include'Subsages / safety.php';  
?&gt; 
&lt; / div&gt; 
&lt; / div&gt; 
 
&lt;?php $ a ++;  ?&gt; 
&lt; div class =“tabcontent2”id =“tab_content_&lt;?php echo $ a;?&gt;”  &lt;?php if($ formname == 4 AND $ formID == null){echo“style ='display:block'”;}?&gt;&gt; 
&lt; div class =“tabs-content3”&gt;  
&lt;?php 
包含'Subpages / faqs.php';  
?&gt; 
&lt; / div&gt; 
&lt; / div&gt;

    You look for something like this?

    <?php if($formname == 4 AND $formID == null):?>
    <div class="tabcontent2" id="tab_content_<?php echo $a; ?>">
        <div class="tabs-content3">
            <?php 
                include 'Subpages/overview.php'; 
             ?> 
        </div>
    </div>
    
    <?php $a++; ?>
    <div class="tabcontent2" id="tab_content_<?php echo $a; ?>" >
        <div class="tabs-content3">
            <?php 
                include 'Subpages/abroad.php'; 
            ?>
        </div>
    </div>
    
    <?php $a++;?>
    <div class="tabcontent2" id="tab_content_<?php echo $a; ?>" >
        <div class="tabs-content3">
            <?php 
                include 'Subpages/safety.php';  
            ?>
        </div>
    </div>
    
    <?php $a++; ?>
    <div class="tabcontent2" id="tab_content_<?php echo $a; ?>">
        <div class="tabs-content3">
            <?php 
                include 'Subpages/faqs.php';  
            ?>
        </div>
    </div>
    <?php endif; ?>
