How can PHP developers troubleshoot issues with displaying selected options in <select> elements?

When troubleshooting issues with displaying selected options in <select> elements, PHP developers can ensure that the value of the selected option matches the value in the <select> element. They can also check if the selected attribute is correctly set for the desired option. 

&lt;select name=&quot;colors&quot;&gt;
    &lt;option value=&quot;red&quot; &lt;?php echo ($color == &quot;red&quot;) ? &quot;selected&quot; : &quot;&quot;; ?&gt;&gt;Red&lt;/option&gt;
    &lt;option value=&quot;blue&quot; &lt;?php echo ($color == &quot;blue&quot;) ? &quot;selected&quot; : &quot;&quot;; ?&gt;&gt;Blue&lt;/option&gt;
    &lt;option value=&quot;green&quot; &lt;?php echo ($color == &quot;green&quot;) ? &quot;selected&quot; : &quot;&quot;; ?&gt;&gt;Green&lt;/option&gt;
&lt;/select&gt;
