Within the confines of PHP hosting at Jelastic PaaS, the following PHP engine versions are supported:
- PHP 7.3.29
- PHP 7.4.20
- PHP 8.0.8
You can choose the version you need while environment creation and easily switch between them afterwards via topology wizard. The workflow is the following:
1. Click the New Environment button at the top dashboard pane to open the Environment Wizard frame.
2. Navigate to the PHP language tab and pick the preferred application server. Choose the desired engine version by means of the second drop-down list in the central pane.
Specify the resource limits, select the preferred region, type your environment name (or leave the default one) and click the Create button.
3. In order to change the version of PHP for the already existing environment, click the Redeploy containers icon next to the appropriate layer.
4. Select required engine version within the Tag list of the opened frame.
Click Redeploy to confirm the changes.
