| ======================================== | |
| 1. Backward Incompatible Changes | |
| ======================================== | |
| - Core | |
| . list() now always supports ArrayAccess and never supports strings. | |
| Previously both were accepted in some situations and not in others. | |
| (RFC: https://wiki.php.net/rfc/fix_list_behavior_inconsistency) | |
| . Bitwise shifts by negative numbers of bits are disallowed (throws E_WARNING | |
| and gives FALSE, like a division by zero). | |
| . Left bitwise shifts by a number of bits beyond the bit width of an integer | |
| will always result in 0, even on CPUs which wrap around. | |
| . Right bitwise shifts by a number of bits beyond the bit width of an integer | |
| will always result in 0 or -1 (depending on sign), even on CPUs which wrap | |
| around. | |
| . Removed ASP (<%) and script (<script language=php>) tags. | |
| (RFC: https://wiki.php.net/rfc/remove_alternative_php_tags) | |
| . call_user_method() and call_user_method_array() no longer exists. | |
| . PHP 7 doesn't keep original values of arguments passed to user functions, | |
| so func_get_arg() and func_get_args() will return current value of argument | |
| instead of the actually passed. The following code is going to be affected: | |
| function foo($x) { $x = 2; return func_get_arg(0);} var_dump(foo(1)); | |
| It will now produce 2, not 1. | |
| . Function parameters with duplicate name are not allowed anymore. Definitions | |
| like “function foo($x,$x) {}” will lead to compile time error. | |
| . Indirect variable, property and method references are now interpreted with | |
| left-to-right semantics. See details in: | |
| https://wiki.php.net/rfc/uniform_variable_syntax#semantic_differences_in_existing_syntax | |
| . The global keyword now only accepts simple variables. See details in: | |
| https://wiki.php.net/rfc/uniform_variable_syntax#global_keyword_takes_only_simple_variables | |
| - DBA | |
| . dba_delete() now returns false if the key was not found for the inifile | |
| handler, too. | |
| - GMP | |
| . Requires libgmp version 4.2 or newer now. | |
| . gmp_setbit() and gmp_clrbit() now return FALSE for negative indices, making | |
| them consistent with other GMP functions. | |
| ======================================== | |
| 2. New Features | |
| ======================================== | |
| - Core | |
| . Added null coalesce operator (??). | |
| (RFC: https://wiki.php.net/rfc/isset_ternary) | |
| . Support for strings with length >= 2^31 bytes in 64 bit builds | |
| . Closure::call() method added | |
| - Standard | |
| . intdiv() function for integer division added. | |
| ======================================== | |
| 3. Changes in SAPI modules | |
| ======================================== | |
| - FPM | |
| . Fixed bug #65933 (Cannot specify config lines longer than 1024 bytes). | |
| . Listen = port now listen on all addresses (IPv6 and IPv4-mapped). | |
| ======================================== | |
| 4. Deprecated Functionality | |
| ======================================== | |
| ======================================== | |
| 5. Changed Functions | |
| ======================================== | |
| - parse_ini_file(): | |
| - parse_ini_string(): | |
| Added scanner mode INI_SCANNER_TYPED to yield typed .ini values. | |
| - unserialize(): | |
| Added second parameter for unserialize function | |
| (RFC: https://wiki.php.net/rfc/secure_unserialize) allowing to specify | |
| acceptable classes: | |
| unserialize($foo, ["allowed_classes" => ["MyClass", "MyClass2"]); | |
| ======================================== | |
| 6. New Functions | |
| ======================================== | |
| - GMP | |
| Added gmp_random_seed() | |
| ======================================== | |
| 7. New Classes and Interfaces | |
| ======================================== | |
| ======================================== | |
| 8. Removed Extensions | |
| ======================================== | |
| ======================================== | |
| 9. Other Changes to Extensions | |
| ======================================== | |
| ======================================== | |
| 10. New Global Constants | |
| ======================================== | |
| - Core | |
| . PHP_INT_MIN added. | |
| ======================================== | |
| 11. Changes to INI File Handling | |
| ======================================== | |
| - Core | |
| . Removed asp_tags ini directive. Trying to enable it will result in a fatal | |
| error. | |
| ======================================== | |
| 12. Windows Support | |
| ======================================== | |
| - Core | |
| . Support for native 64 bit integers in 64 bit builds | |
| . Support for large files in 64 bit builds | |
| ======================================== | |
| 13. Other Changes | |
| ======================================== | |
| - Core | |
| . Instead of being undefined and platform-dependent, NaN and Infinity will | |
| always be zero when casted to integer. | |
| . Calling a method on a non-object no longer raises a fatal error; see | |
| also: https://wiki.php.net/rfc/catchable-call-to-member-of-non-object |
