Create a PHP web app in Azure

Azure Web Apps provides a highly scalable, self-patching web hosting service. This quickstart tutorial shows how to deploy a PHP app to Azure Web Apps. You create the web app using the Azure CLI in Cloud Shell, and you use Git to deploy sample PHP code to the web app.

Sample app running in Azure]

You can follow the steps below using a Mac, Windows, or Linux machine. Once the prerequisites are installed, it takes about five minutes to complete the steps.

Prerequisites

To complete this quickstart:

If you don't have an Azure subscription, create a free account before you begin.

Download the sample locally

In a terminal window, run the following commands. This will clone the sample application to your local machine, and navigate to the directory containing the sample code.

git clone https://github.com/Azure-Samples/php-docs-hello-world
cd php-docs-hello-world

Run the app locally

Run the application locally by opening a terminal window and using the php command to launch the built-in PHP web server.

php -S localhost:8080

Open a web browser, and navigate to the sample app at http://localhost:8080.

You see the Hello World! message from the sample app displayed in the page.

Sample app running locally

In your terminal window, press Ctrl+C to exit the web server.

Launch Azure Cloud Shell

The Azure Cloud Shell is a free Bash shell that you can run directly within the Azure portal. It has the Azure CLI preinstalled and configured to use with your account. Click the Cloud Shell button on the menu in the upper-right of the Azure portal.

Cloud Shell

The button launches an interactive shell that you can use to run the steps in this topic:

Create a deployment user

In the Cloud Shell, create deployment credentials with the az webapp deployment user set command.

A deployment user is required for FTP and local Git deployment to a web app. The user name and password are account level. They are different from your Azure subscription credentials.

In the following command, replace <username> and <password> with a new user name and password. The user name must be unique. The password must be at least eight characters long, with two of the following three elements: letters, numbers, symbols.

az webapp deployment user set --user-name <username> --password <password>

If you get a 'Conflict'. Details: 409 error, change the username. If you get a 'Bad Request'. Details: 400 error, use a stronger password.

You create this deployment user only once; you can use it for all your Azure deployments.

Note

Record the user name and password. You need them to deploy the web app later.

Create a resource group

In the Cloud Shell, create a resource group with the az group create command.

A resource group is a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed.

The following example creates a resource group named myResourceGroup in the West Europe location.

az group create --name myResourceGroup --location "West Europe"

You generally create your resource group and the resources in a region near you. To see all supported locations for Azure Web Apps, run the az appservice list-locations command.

Create an Azure App Service plan

In the Cloud Shell, create an App Service plan with the az appservice plan create command.

An App Service plan specifies the location, size, and features of the web server farm that hosts your app. You can save money when hosting multiple apps by configuring the web apps to share a single App Service plan.

App Service plans define:

  • Region (for example: North Europe, East US, or Southeast Asia)
  • Instance size (small, medium, or large)
  • Scale count (1 to 20 instances)
  • SKU (Free, Shared, Basic, Standard, or Premium)

The following example creates an App Service plan named myAppServicePlan in the Free pricing tier:

az appservice plan create --name myAppServicePlan --resource-group myResourceGroup --sku FREE

When the App Service plan has been created, the Azure CLI shows information similar to the following example:

{ 
  "adminSiteName": null,
  "appServicePlanName": "myAppServicePlan",
  "geoRegion": "West Europe",
  "hostingEnvironmentProfile": null,
  "id": "/subscriptions/0000-0000/resourceGroups/myResourceGroup/providers/Microsoft.Web/serverfarms/myAppServicePlan",
  "kind": "app",
  "location": "West Europe",
  "maximumNumberOfWorkers": 1,
  "name": "myAppServicePlan",
  < JSON data removed for brevity. >
  "targetWorkerSizeId": 0,
  "type": "Microsoft.Web/serverfarms",
  "workerTierName": null
} 

Create a web app

In the Cloud Shell, create a web app in the myAppServicePlan App Service plan with the az webapp create command.

The web app provides a hosting space for your code and provides a URL to view the deployed app.

In the following command, replace <app_name> with a unique name (valid characters are a-z, 0-9, and -). If <app_name> is not unique, you get the error message "Website with given name <app_name> already exists." The default URL of the web app is https://<app_name>.azurewebsites.net.

az webapp create --name <app_name> --resource-group myResourceGroup --plan myAppServicePlan --deployment-local-git

When the web app has been created, the Azure CLI shows information similar to the following example:

{
  "availabilityState": "Normal",
  "clientAffinityEnabled": true,
  "clientCertEnabled": false,
  "cloningInfo": null,
  "containerSize": 0,
  "dailyMemoryTimeQuota": 0,
  "defaultHostName": "<app_name>.azurewebsites.net",
  "enabled": true,
  "enabledHostNames": [
    "<app_name>.azurewebsites.net",
    "<app_name>.scm.azurewebsites.net"
  ],
  "gatewaySiteName": null,
  "hostNameSslStates": [
    {
      "hostType": "Standard",
      "name": "<app_name>.azurewebsites.net",
      "sslState": "Disabled",
      "thumbprint": null,
      "toUpdate": null,
      "virtualIp": null
    }
    < JSON data removed for brevity. >
}

Browse to the site to see your newly created web app.

http://<app_name>.azurewebsites.net

Empty web app page

You’ve created an empty new web app in Azure.

Configure local Git deployment

Configure local Git deployment to the web app with the az webapp deployment source config-local-git command.

App Service supports several ways to deploy content to a web app, such as FTP, local Git, GitHub, Visual Studio Team Services, and Bitbucket. For this quickstart, you deploy by using local Git. That means you deploy by using a Git command to push from a local repository to a repository in Azure.

In the following command, replace <app_name> with your web app's name.

az webapp deployment source config-local-git --name <app_name> --resource-group myResourceGroup --query url --output tsv

The output has the following format:

https://<username>@<app_name>.scm.azurewebsites.net:443/<app_name>.git

The <username> is the deployment user that you created in a previous step.

Copy the URI shown; you'll use it in the next step.

Push to Azure from Git

In the local terminal window, add an Azure remote to your local Git repository.

git remote add azure <URI from previous step>

Push to the Azure remote to deploy your app with the following command. When prompted for a password, make sure that you enter the password you created in Configure a deployment user, not the password you use to log in to the Azure portal.

git push azure master

The preceding command displays information similar to the following example:

Browse to the app locally

Browse to the deployed application using your web browser.

http://<app_name>.azurewebsites.net

The PHP sample code is running in an Azure App Service web app.

Sample app running in Azure

Congratulations! You've deployed your first PHP app to App Service.

Update locally and redeploy the code

Using a local text editor, open the index.php file within the PHP app, and make a small change to the text within the string next to echo:

echo "Hello Azure!";

Commit your changes in Git, and then push the code changes to Azure.

git commit -am "updated output"
git push azure master

Once deployment has completed, switch back to the browser window that opened in the Browse to the app step, and refresh the page.
