What is the significance of using the name attribute in <input> elements for POST transmission in PHP?

When submitting a form using the POST method in PHP, the name attribute in <input> elements is crucial for identifying the data being sent. Without the name attribute, the data from the input fields will not be accessible in the PHP script using the $_POST superglobal. Therefore, it is important to ensure that all input fields have a unique name attribute assigned to them. 

&lt;form method=&quot;post&quot; action=&quot;process_form.php&quot;&gt;
    &lt;input type=&quot;text&quot; name=&quot;username&quot;&gt;
    &lt;input type=&quot;password&quot; name=&quot;password&quot;&gt;
    &lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
&lt;/form&gt;
