What does undefined symbol: zend_hash_destroy mean?
A. This can occur if PHP is configured with the option: –enable-versioning This option can prevent the export of global PHP API symbols, causing failure when attempting to link libraries such as the Loader or Zend Optimiser. PHP must be rebuilt without that option so that the PHP API is correctly visible. A phpinfo page should show at the top of the page what options were used to configure PHP, and should confirm that the option had been used.
