修改PHP变量内的内容

Question

I have this:

$data = '<tag>content</tag>';

And I'd like to know if it's possible to modify the content inside the tags as shown, and how.

For example, if the user inputs "car", then the variable should be:

$data = '<tag>car</tag>';

This is for the purpose of inserting user input from an HTML form into the variable. The variable itself is supposed to contain an XML structure.

Answer 1

if I understand your question correctly you want to get the user's input and save it to the variable $data

try this (if your using POST method)

$HTMLdata = $_POST['inputfieldname'];
$data = "<tag>".$HTMLdata."</tag>";

I hope I helped you

Answer 2

为什么不只是在用户输入周围连接标签？

$data = '<tag>'.$_POST['input'].'</tag>';
