java - When executing a function in php, how to automatically call a link address within the function

For example, if I execute the show() method in a.php, I want to jump to b.php after the function is executed. There is window.location.href in JS. What should I use in php? I forgot

1. Use header function

   <code class="php">header("Location: https://post.zz173.com",true,301); 
   //确保重定向后，后续代码不会被执行 
   exit;</code>

   Copy after login

2. Write meta tag

   <code class="html"><meta http-equiv="refresh" 
   content="1;url=https://post.zz173.com"> </code>

   Copy after login

3. Write javascript tag

   <code class="php"><php?
   echo "< script language='javascript' 
   type='text/javascript'>";  
   echo "window.location.href='https://post.zz173.com'";  
   echo "< /script>";  </code>

   Copy after login

headerThat’s the method. Try it

<code>header("Location:b.php"); exit();</code>
