PHP page jump operation example analysis (header method)

This article analyzes the PHP page jump operation with an example. Share it with everyone for your reference, the details are as follows:

Jump

header() is a php function that sends specified commands to the browser

html:

<meta http-equiv="Refresh" content="3;url=other.php"/>

Jump immediately:

header('Location:other.php');
//file_put_contents('bee.txt','execute');
die;

When executing the header, it does not end immediately, but the page will be executed; there cannot be any output in front of the header. If output buffering is turned on, no error will be prompted. php.ini->output_buffering = 4096|OFF

Prompt Jump:

header('Refresh:3,Url=other.php');
echo '3s 后跳转';
//由于只是普通页面展示，提示的样式容易定制
die;

Encapsulated jump function:

/*
 *跳转
 *@param $url 目标地址
 *@param $info 提示信息
 *@param $sec 等待时间
 *return void
*/
function jump($url,$info=null,$sec=3)
{
 if(is_null($info)){
  header("Location:$url");
 }else{
  // header("Refersh:$sec;URL=$url");
  echo"<meta http-equiv=\"refresh\" content=".$sec.";URL=".$url.">";
  echo $info;
 }
 die;
}
