我们可以访问$ _POST作为变量名吗？ [关闭]

Is it possible to access each post variable where variable name should be accessible as

$_POST['field1'];
$_POST['field1'];
$_POST['field1'];
............so on

Edit: I am trying to pass $_post as an argument to a function and then inside the function I want to have each post variable accessible as a name on which i could then run operations.

It seems like you need just a simple example of a form and a php file that uses the information from the form after it's been submitted.

HTML

<form method="post" action="doStuff.php">
  First Name:<input type="text" name="fname" />
  Last Name:<input type="text" name="lname" />
  <input type="submit" name="submit" value="submit" />
</form>

doStuff.php

if( isset($_POST["submit"}) ) {

  $fname = $_POST["fname"];
  $lname = $_POST["lname"];

  processPOST($fname, $lname);
}

function processPOST($fname, $lname){

  // Do whatever you need

}

or simply, doStuff.php The Second

if( isset($_POST["submit"}) ) {

  $fname = $_POST["fname"];
  $lname = $_POST["lname"];

  // Do whatever you need
}

Take a look at extract function PHP documentation here

Yes, you can easily pass $_POST as an argument to a function.

function withPosts($_POST['field_name'], $field_name2){
    //Some code here
}

But inside the function you have to refer them by variables as per function declaration.

function withPosts($field1, $field2){
    echo $field1; // Correct
    echo $_POST['field_name']; // Incorrect
}
