Redline13.com Custom PHP Load Test Downloading Credentials

<?php

/**
 * This example is for writing a Custom PHP Load Test on redline13.com that might need to pick a random E-mail or other data.
 * If placed inside of the CustomTest constructor, you can download a list of E-mails and randomly pick one to use for the test.
 * The initial locking part ensures that the file is only downloaded once.
 * This approach can be used to download other types of files that might be needed as well.
 * For example, if you need to test uploading files, this can be used to download the files that you will be uploading in your test.
