Bug Type: Feature/Change Request
Bug description:extra CPU operation on each usage or E_* error types
Description:
------------
the way the errors are defined in zend_errors.h file makes an extra
unneeded cpu shift (multiplication?) operation each time the error constant
is used.
clue:
this is is from zend_errors.h:
#define E_ERROR (1<<0L)
if you printf( "%d" , E_ERROR ) the pre-processor will replace this line
with
printf( "%d" , 1<<0L ) which will cause an uncalled for shit operation
Test script:
---------------
/*
this script will cause a php E_NOTICE to be used, notice the (minor) diff
in execution time when error definitions are changed
*/
error_reporting( E_ALL );
for( $i=0 ; $i<10000000; $i++ ) {
echo $x['a'];
}
Expected result:
----------------
no change to the output is a must
