<p>To drop a foreign key, you may use the&nbsp;dropForeign&nbsp;method. Foreign key constraints use the same naming convention as indexes. So, we will concatenate the table name and the columns in the constraint then suffix the name with &quot;_foreign&quot;:</p>

<p>$table-&gt;dropForeign(&#39;posts_user_id_foreign&#39;);</p>
