Direct Known Subclasses:

public class PhpServletLocalHttpServerScriptEngine
extends PhpScriptEngine

A PHP script engine for Servlets. See ContextLoaderListener for details. In order to evaluate PHP methods follow these steps:

1. Create a factory which creates a PHP script file from a reader using the methods from EngineFactory:

   private static File script;
private static final File getHelloScript() {
if (script!=null) return script;

String webCacheDir = ctx.getRealPath(req.getServletPath());
Reader reader = new StringReader ("<?php echo 'hello from PHP'; ?>");
return EngineFactory.getPhpScript(webCacheDir, reader);
}


2. Acquire a PHP script engine from the EngineFactory:

   ScriptEngine scriptEngine = EngineFactory.getPhpScriptEngine(this, ctx, req, res, "HTTP", 80);

3. Create a FileReader for the created script file:

   Reader readerHello = EngineFactory.createPhpScriptFileReader(getHelloScript());

4. Connect its output:

   scriptEngine.getContext().setWriter (out);

5. Evaluate the engine:

   scriptEngine.eval(readerHello);

6. Close the reader:

   readerHello.close();
