I have managed to write a small, compilable extension for php, that prints "test" on every ZEND_RINIT.
I tested it with an php-file that loads multiple other files, which again load others [...]. The problem is, that the extension just prints "test" once, so I assume it does not fire each time a new file is loaded, how can i get my extension to do so?
Also the event is fired before the file is loaded, that is what i want, but therefore zend_get_executed_filename() is empty and I am not able to get the file content...
My final goal is to validate each file before executing the script. I planned on doing so by validating a file signature that is appended to the file.
Pseudocode Validation:
decrypt(signature, rsa.pub) = sha(filecontent)
Pseudocode Signing:
signature = encrypt(sha(filecontent), rsa.priv)
file += signature
Or is there an even better way to validate the files (i want them to be signed) before executing the script in them?
Thanks in advance!
ZEND_RINIT is called on request startup, that is when you execute your php-file. It will never be called again during execution of your PHP file. Only on next startup. You have to find a way to hook into all of the file load functions of PHP.
