function PrettyPrinterAbstract::__construct

Creates a pretty printer instance using the given options.

Supported options:

• PhpVersion $phpVersion: The PHP version to target (default to PHP 7.4). This option controls compatibility of the generated code with older PHP versions in cases where a simple stylistic choice exists (e.g. array() vs []). It is safe to pretty-print an AST for a newer PHP version while specifying an older target (but the result will of course not be compatible with the older version in that case).
• string $newline: The newline style to use. Should be "\n" (default) or "\r\n".
• string $indent: The indentation to use. Should either be all spaces or a single tab. Defaults to four spaces (" ").
• bool $shortArraySyntax: Whether to use [] instead of array() as the default array syntax, if the node does not specify a format. Defaults to whether the phpVersion support short array syntax.

Parameters

array{: phpVersion?: PhpVersion, newline?: string, indent?: string, shortArraySyntax?: bool } $options Dictionary of formatting options
