## Deploying an SCA component

There are no special steps needed to deploy a PHP SCA component. It is sufficient to place the component PHP script in its proper place under the web server document root, just like any other PHP script. It is the SCA::initComponent executable line within each component that will be executed whenever the script is called, and which will be responsible for making the component respond appropriately to Web service calls, local calls, or requests for WSDL.
