I have a C++ based php-extension accessing a C++ based non-php .so data engine, which reads and writes using the open/read/write/close calls in fcntl.h.
The non-php engine is reliable away from php, but when accessed via the php extension, it works, but runs into two forms of errors: a) seek/read/write errors - one moment it reads fine, the next it fails. b) data corruption/variable switching - looks like variables are getting confused as to their appropriate value, which smacks of a threading issue. Regarding a) streams: Must any file access either in an extension directly, or in a library or .so object called by that extension, use php streams, to be safe? Or is there a way to allow them to use native system calls, without the strange errors? Regarding b) threads: Is there a useful reference as to the threading model in zend/php, and/or its relation to the apache threading model?
