Description: ------------ I'm using the embed SAPI, and I came across an issue when using zend_hash_compare(). I wanted to use the provided hash_zval_compare_function() as the callback function for the compar parameter. However, I cannot use this, since it is not exposed. I could use zend_compare_arrays(), but it doesn't allow me to pass in a 1 as the value of the ordered parameter sent to zend_hash_compare(). Since I want to compare arrays like comparing with the identity operator, then I need to use zend_hash_compare() and create my own callback that does exactly what hash_zval_compare_function() does, thus reinventing the wheel. Either: 1) Expose hash_zval_compare_function() so it can be used by third-party apps - or - 2) Make a second version of zend_compare_arrays() that allows you to compare arrays by identity (i.e. zend_compare_arrays_identity()?)
