How to use post to jump to the page in php

How to use POST to jump to the page:

Everyone knows that PHP can use header('Location') Implement get request jump.

php can use curl to simulate post requests.

But I can’t find a ready-made PHP implementation of post jump.

Then the question is, if there is such a need, how to realize it?

Here today, I will share with you a PHP post jump method using form js.

index.php(initiate jump page)

<?php
//定义post处理页面url
$actionUrl = &#39;./action.php&#39; ;
 
//获取当前页面的url
$url = &#39;http://&#39; . $_SERVER [ &#39;HTTP_HOST&#39; ]. $_SERVER [ &#39;PHP_SELF&#39; ]. &#39;?&#39; . $_SERVER [ &#39;QUERY_STRING&#39; ];
 
//解析url
$parseInfo = parse_url ( $url );
 
//获取url中的参数部分
$queryString = $parseInfo [ &#39;query&#39; ];
 
//将querycan参数解析到数组变量
$queryArr =[];
parse_str ( $queryString , $queryArr );
 
//循环拼接表单项
$formItemString = &#39;&#39; ;
foreach ( $queryArr  as  $key => $value ){
     $formItemString .= "<input name=&#39;{$key}&#39; type=&#39;text&#39; value=&#39;{$value}&#39;/>" ;
}
 
//构造表单并跳转
$content =<<<EOF
<form style= &#39;display:none&#39;  name= &#39;submit_form&#39;  id= &#39;submit_form&#39;  action= &#39;{$actionUrl}&#39;  method= &#39;post&#39; >
{ $formItemString }
</form>
<script type= "text/javascript" >
document.submit_form.submit();
</script>
EOF;
 
exit ( $content );

action.php(jump target page)

<?php
//打印post接收到的数据
echo  print_r( $_POST ,true);
