Upgrading from PHP-Parser 4.x to 5.0
|
|
====================================
|
|
|
|
### PHP version requirements
|
|
|
|
PHP-Parser now requires PHP 7.1 or newer to run. It is however still possible to *parse* code for older versions, while running on a newer version.
|
|
|
|
### Changes to the default pretty printer
|
|
|
|
A number of changes to the standard pretty printer have been made, to make it match contemporary coding style conventions (and in particular PSR-12). Options to restore the previous behavior are not provided, but it is possible to override the formatting methods (such as `pStmt_ClassMethod`) with your preferred formatting.
|
|
|
|
Return types are now formatted without a space before the `:`:
|
|
|
|
```php
|
|
# Before
|
|
function test() : Type
|
|
{
|
|
}
|
|
|
|
# After
|
|
function test(): Type
|
|
{
|
|
}
|
|
```
|
|
|
|
`abstract` and `final` are now printed before visibility modifiers:
|
|
|
|
```php
|
|
# Before
|
|
public abstract function test();
|
|
|
|
# After
|
|
abstract public function test();
|
|
```
|
|
|
|
A space is now printed between `use` and the following `(` for closures:
|
|
|
|
```php
|
|
# Before
|
|
function () use($var) {
|
|
};
|
|
|
|
# After
|
|
function () use ($var) {
|
|
};
|
|
```
