Run PHP in memory

Question

As I can't write file on the GAE server, is there a way that I can directly run PHP code in memory without the help of a php file. BTW, I was using Quercus to run PHP in GAE.
You can refer to the link: http://www.webdigi.co.uk/blog/2009/run-php-on-the-google-app-engine/
Thank you so much.

Answer 1

You can use eval() from PHP to execute a string of PHP code without saving it to a file.

For example:

eval('echo hi;'); // this echoes "hi"
