# Chapter 7 - Removal - Remove customer accounts from the database

**Objective**: A Web application for listing and deleting customers.\
 **Difficulty**: \*

## Preparation <a href="#chapter7-removal-removecustomeraccountsfromthedatabase-preparation" id="chapter7-removal-removecustomeraccountsfromthedatabase-preparation"></a>

Duplicate file `list_the_clients.php` from Section 3.3 to a file named `D-CRUD.php` at the root of your Web server.

For this last part, we will learn how to delete a resource.

Here is the complete, detailed call you need to remove a client:

```
try {
  $webService = new PrestaShopWebservice( '[http://mystore.com/|http://mystore.com/]' , 'ZR92FNY5UFRERNI3O9Z5QDHWKTP3YIIT' , false ); // Create an instance{color}
  $opt[ 'resource' ] = 'customers';          // Resource to use{color}
  $opt[ 'id' ] = 3;                          // ID to use{color}
  $webService->delete( $opt );               // Delete{color}
  echo 'Client '.3.' successfully deleted!'; // If we can see this message then that means that we have not left the try block
}
catch (PrestaShopWebserviceException $ex) {
  $trace = $ex->getTrace();                // Recuperate all info on this error
  $errorCode = $trace[ 0 ][ 'args' ][ 0 ]; // Recuperate error code 
  if ( $errorCode == 401 ) 
    echo 'Bad auth key';   
  else 
    echo 'Other error : <br />'.$ex->getMessage(); 
  // Display error message{color}
}
```

This code allows you to remove a customer whose ID is "3". As you can see, deleting the customer differs only slightly from retrieving a resource. In fact the only thing different in the code lies in the method called: We will no longer call this method "get" but instead simply "delete"!

You must now replace the customer ID by a dynamically-defined ID.

Now create all the script that will display a list of customer IDs and delete a customer of your choice.

Again, if you have trouble, look at the code for `4-delete.php`.
