Changed zend_make_printable_zval() to return "use_copy" instead of additional reference argument.
Improved branch prediction.

Reverted 387c491559f1507685740bf613070d27bce59e4d (it broke ext/standard/tests/file/bug44607.phpt)

op2 is null terminated string

Comparison optimization

Speedup string equality check

cleanup

Use new zend_hash API

Fix ** operator with references

Fix incdec of ref object properties

This fixes a number of infinite loops in the Symfony testsuite. It
took an obscene amount of time to track this down :/

Use specialized functions instead of macros

Added folder mark and codes style

Added folder mark

Use optimized zend_array_dup() function. convert zend_hash_num_elements() and zend_hash_next_free_element() into macros.

Optimize int to string conversion

Probably platform depedentant, but for me snprintf is terribly
slow.

The code for the long printing is taken from the smart string
API.

Assert that EMPTY_SWITCH_DEFAULT_CASE() cannot be reached in debug

C89 compat

Added vstrpprintf strpprintf to avoid duplicate string

(the function name maybe improvement)

Fix identical comparison of arrays with references

Also commit a test I forgot.

Fix SXE->string cast for __toString in inheriting class

This issue was originally hacked around in zend_make_printable_zval.
I've now moved the overridden __toString() handling into the

Fix SXE->string cast for __toString in inheriting class

This issue was originally hacked around in zend_make_printable_zval.
I've now moved the overridden __toString() handling into the SXE
cast_object handler, so everything invoking that handler
(zend_make_printable_zval, convert_to_string, zval_get_string,
and various other more obscure usages) see the same behavior.

Avoid superflous allocations in convert_to_string

Taken from zval_get_string.

Split IS_BOOL into IS_FALSE and IS_TRUE

Add dst parameter to convert_object_to_type macro

Avoids a ZVAL_DUP in the zval_get_* functions.

Also improve object-to-array cast a bit by initializing the array
with correct n

Add dst parameter to convert_object_to_type macro

Avoids a ZVAL_DUP in the zval_get_* functions.

Also improve object-to-array cast a bit by initializing the array
with correct number of elements and not doing a alloc-init-free
cycle when convert_object_to_type succeeds.

Use convert_scalar_to_array only for arrays

Align zval_get_long/double with zval_get_string

Fixed compilation warnings
