Here is the raw list of all possible ini settings that can go in your /etc/hhvm/php.ini or /etc/hhvm/server.ini file. Not all of them are useful, many are redundant, tons are useless (or only useful at Facebook scale) and many others are useful. There is lots of cleanup work to do here, but for now you get a sorted list, sorry.
This list is just the HHVM-specific options. Many standard PHP options are also supported by HHVM, meaning the same thing that they do to PHP5. So your favorite option may just work out of the box with the same name.
| INI Setting | Documentation | Default |
|---|---|---|
| hhvm.admin_server.password | A password required for all requests to the admin server, other than the index. Is passed to the request as the auth request var. |
empty string |
| hhvm.admin_server.port | The port the admin server should listen on. If set to 0, the admin server is not started. | 0 |
| hhvm.admin_server.thread_count | The number of threads the admin server should use. | 1 |

| hhvm.enable_numa_local | ||
| hhvm.enable_obj_destruct_call | If false, __destruct() methods will not be called on an object at the end of the request. This can be a performance benefit if your system and application can handle the memory requirements. Deallocation can occur all at one time. If true, then HHVM will run all __destruct() methods in the usual way |
False |

|
True |

| hhvm.force_hh | Treat all code as Hack, even if it starts with <?php. This is a sort of "master option" -- several other behavioral options have their defaults to be whatever this option is set to. See below. |
False |
The translation cache stores the JIT'd code. It's split into several sections depending on how often the code is (or is expected to be) executed. The sum of all the bits has to be less than 2GB.
| INI Setting | Documentation | Default |
|---|---|---|
| hhvm.jit_a_size | Size in bytes of main translation cache. | 62914560 (60 MB) |
| hhvm.jit_a_cold_size | Size of cold code cache. Code that is unlikely to be executed is deemed cold. (Recommended: 0.5x hhvm.jit_a_size) | 25165824 (24 MB) |
| hhvm.jit_a_frozen_size | Size of extremely cold code cache. Code that is almost never executed, or executed once and then freed up, is deemed frozen. (Recommended: 1x hhvm.jit_a_size) | 41943040 (40 MB) |
| hhvm.jit_a_hot_size | Size of hot code cache. (Enabled only in RepoAuthoritative mode) | 0 |

For changes from PHP 5 to PHP 7 which are backwards incompatible, INI options are available to choose which behavior HHVM respects. (Features which are not backwards incompatible are always available.)
The vast majority of users will want to just set hhvm.php7.all = 1 to fully enable PHP 7 mode and can ignore the rest of the options in this section. They are available primarily for advanced users who want to do a more gradual migration or otherwise track down compatibility issues.
| INI Setting | Documentation | Default | PHP 7 RFC |
|---|---|---|---|
| hhvm.php7.all | Default value for all of the below | False | N/A |
| hhvm.php7.deprecate_old_style_ctors | Disallow and warn when using old PHP 4 constructors | hhvm.php7.all | Remove PHP 4 Constructors |
| hhvm.php7.int_semantics | Change some edge-case int and float behavior, such as divide/mod by zero | hhvm.php7.all | Integer semantics with some changes due to engine exceptions |
| hhvm.php7.ltr_assign | Make order of assignment in list() lvalues consistent |
hhvm.php7.all | Abstract syntax tree |
| hhvm.php7.no_hex_numerics | Don't consider hex strings to be numeric | hhvm.php7.all | Remove hex support in numeric strings |
| hhvm.php7.scalar_types | Enable PHP 7-style scalar type annotations (NB: not the same as Hack's) | hhvm.php7.all | Scalar type declarations |
| hhvm.php7.uvs | Fix some odd precedence and order of evaluation issues | hhvm.php7.all | Uniform variable syntax |
| INI Setting | Documentation | Default |
|---|---|---|
| hhvm.allow_hhas | Allow executing "hhas" files -- code written directly in HHBC. Directly writing HHBC can easily crash HHVM, and is rarely a useful thing to do anyways. | False |

If a regular return type hint fails, it's possible for execution to resume normally if the user error handler doesn't throw and returns something other than boolean false. 3 - Same as 2, except if a regular type hint fails the runtime will not allow execution to resume normally; if the user error handler returns something other than boolean false, the runtime will throw a fatal error (this goes together with Option::HardReturnTypeHints) | 2 |
