zend_optimizerplus.revalidate_path
If the file search is disabled and a cached file is found that uses the same include_path, the file is not
searched again. Thus, if a file with the same name appears somewhere else in include_path, it won't be
found. Enable this directive if this optimization has an effect on your applications. The default for this
directive is disabled, which means that optimization is active.
Type: boolean
Default Value: 0
Available since version 4.0
zend_optimizerplus.inherited_hack
The Optimizer+ stores the places where DECLARE_CLASS opcodes use inheritance (These are the only
opcodes that can be executed by PHP, but which may not be executed because the parent class is
missing due to optimization). When the file is loaded, Optimizer+ tries to bind the inherited classes by
using the current environment. The problem with this scenario is that, while the DECLARE_CLASS
opcode may not be needed for the current script, if the script requires that the opcode at least be defined,
it may not run. The default for this directive is disabled, which means that optimization is active.
Type: boolean
Default Value: 1
Available since version 4.0
zend_optimizerplus.dups_fix
Enable this hack as a workaround for "duplicate definition" errors
Type: boolean
Default Value: 0
Available since version 4.0
zend_optimizerplus.log_verbosity_level
All Optimizer+ errors go to the Web server log. By default, only fatal errors (level 0) or errors (level 1)
are logged. You can also enable warnings (level 2), info messages (level 3) or debug messesges (level
4). For "debug" binaries, the default log verbosity level is 4, not 1.
Type: integer
Default Value: 1
