### PHP mysqlnd Proxy Connection Example

Source: https://github.com/fmatsos/php-doc/blob/main/doc/mysqlnd.plugin.developing.html

Demonstrates how to create a proxy class extending mysqlnd_plugin_connection to intercept and modify connection and query behavior. It shows how to use 'pre' and 'post' hooks for custom logic.

```php
class proxy extends mysqlnd_plugin_connection {
  public function connect($conn, $host, ...) {
    /* "pre" hook */
    printf("Connecting to host = '%s'\n", $host);
    debug_print_backtrace();
    return parent::connect($conn);
  }

  public function query($conn, $query) {
    /* "post" hook */
    $ret = parent::query($conn, $query);
    printf("Query = '%s'\n", $query);
    return $ret;
  }
}
mysqlnd_plugin_set_conn_proxy(new proxy());
```

### Retrieve MySQL Host Info (Object-Oriented PHP)

Source: https://github.com/fmatsos/php-doc/blob/main/doc/mysqli.get-host-info.html

This PHP example demonstrates how to use the `mysqli::$host_info` property to get connection details in an object-oriented style, including error reporting setup and printing the host information.

```PHP
<?php
    mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
    $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

### PHP Example: Accessing Ds\Vector Elements with get() Method

Source: https://github.com/fmatsos/php-doc/blob/main/doc/ds-vector.get.html

Demonstrates how to retrieve elements from a `Ds\Vector` using the `get()` method. This example initializes a vector and then uses `get()` with different indices to fetch and display the corresponding values.

```PHP
<?php
  $vector = new \Ds\Vector(["a", "b", "c"]);

  var_dump($vector->get(0));
  var_dump($vector->get(1));
  var_dump($vector->get(2));
?>
```
