========================================
|
|
1. Backward Incompatible Changes
|
|
========================================
|
|
|
|
- Intl:
|
|
. The default parameter value of idn_to_ascii() and idn_to_utf8() is now
|
|
INTL_IDNA_VARIANT_UTS46 instead of the deprecated INTL_IDNA_VARIANT_2003.
|
|
|
|
- Reflection:
|
|
. Reflection objects will now generate an exception if an attempt is made
|
|
to serialize them. Serialization for reflection objects was never
|
|
supported and resulted in corrupted reflection objects. It has been
|
|
explicitly prohibited now.
|
|
|
|
========================================
|
|
2. New Features
|
|
========================================
|
|
|
|
- PDO_OCI:
|
|
. PDOStatement::getColumnMeta is now available
|
|
|
|
- PDO_SQLite:
|
|
. PDOStatement::getAttribute(PDO::SQLITE_ATTR_READONLY_STATEMENT) allows to
|
|
check whether this statement is read-only, i.e. whether it doesn't modify
|
|
the database.
|
|
|
|
========================================
|
|
3. Changes in SAPI modules
|
|
========================================
|
|
|
|
========================================
|
|
4. Deprecated Functionality
|
|
========================================
|
|
|
|
- Core:
|
|
. Unbinding $this of a non-static method through a combination of
|
|
ReflectionMethod::getClosure() and closure rebinding is deprecated. Doing
|
|
so is equivalent to calling a non-static method statically, which has been
|
|
deprecated since PHP 7.0.
|
|
|
|
========================================
|
|
5. Changed Functions
|
|
========================================
|
|
|
|
========================================
|
|
6. New Functions
|
|
========================================
|
|
|
|
========================================
|
|
7. New Classes and Interfaces
|
|
========================================
|
|
|
|
========================================
|
|
8. Removed Extensions and SAPIs
|
|
========================================
|
|
|
|
========================================
|
|
9. Other Changes to Extensions
|
|
========================================
|
|
|
|
- Hash:
|
|
. The hash extension cannot be disabled anymore and is always an integral
|
|
part of any PHP build, similar to the date extension.
|
|
|
|
- Intl:
|
|
. The Intl extension now requires at least ICU 50.1.
|
|
|
|
- Libxml:
|
|
. All libxml based extensions now require libxml 2.7.6 or newer.
|
|
|
|
- Reflection:
|
|
. Numeric value of class, property, function and constant modifiers was
|
|
changed. Don't filter methods and properties through
|
|
ReflectionClass::getMethods() and ReflectionClass::getProperties(), or test
|
|
results of Reflection...::getModifiers(), using hard-coded numeric values.
|
|
Use corresponding constants instead (e.g. ReflectionMethod::IS_PUBLIC).
|
|
|
|
- Zip:
|
|
. The bundled libzip library has been removed. A system libzip >= 0.11 is now
|
|
necessary to build the extension.
|
|
|
|
========================================
|
|
10. New Global Constants
|
|
========================================
|
|
|
|
========================================

11. Changes to INI File Handling

12. Windows Support
