PHP compatible serialization from C/C++
php
Solution
There are several implementations for other languages here
http://objectmix.com/php/362009-specification-serialize.html#post1335166
The C implementation used by PHP itself is also here:
http://svn.php.net/repository/php/php-src/branches/PHP_5_2/ext/standard/var.c
http://svn.php.net/repository/php/php-src/branches/PHP_5_2/ext/standard/var_unserializer.c
However, unless you're absolutely certain that your choice serialization format is going to be a major bottleneck, consider using a more readily available serialization format, like JSON, XML, Protocol Buffers, or WDDX.
Problem
Anyone know of a library that allows data to be serialized in C++ such that it can be deserialized using the default PHP 'unserialize' function?
