从URL中选择PHP数组

Question

I have coded a internal messenger system for the company I work for and I am trying to make things easier for myself by making a admin panel for this so it can control the usernames, passwords and groups.

Basically I am trying to select a user from the array using a url ?user=username which will then return the user information and allow it to be changed. The problem I am having is to get the url to select the username in the array.

The array is basic:

$users = array(
    '0' => array(
        'username' => 'test',
        'password' => 'test123',
        'group' => 'office',
    ),

Answer 1

Like this?:

<?php

// get username from URL (GET METHOD)
$username=$_GET["username"];

// $users has all the info

foreach ($users as $u) {
  // find the target user
  if ($u["username"] == $username) {
      // do something with $u
      var_dump($u);
  }
}

?>
