Namespaces

SlevomatCodingStandard.Namespaces.AlphabeticallySortedUses 🔧

Sniff checks whether use declarations at the top of a file are alphabetically sorted. Follows natural sorting and takes edge cases with special symbols into consideration. The following code snippet is an example of correctly sorted uses:

use LogableTrait;
use LogAware;
use LogFactory;
use LoggerInterface;
use LogLevel;
use LogStandard;

Sniff provides the following settings:

• psr12Compatible (defaults to true): sets the required order to classes, functions and constants. false sets the required order to classes, constants and functions.
• caseSensitive: compare namespaces case sensitively, which makes this order correct:

use LogAware;
use LogFactory;
use LogLevel;
use LogStandard;
use LogableTrait;
use LoggerInterface;

SlevomatCodingStandard.Namespaces.DisallowGroupUse

Group use declarations are ugly, make diffs ugly and this sniff prohibits them.

SlevomatCodingStandard.Namespaces.FullyQualifiedExceptions 🔧

This sniff reduces confusion in the following code snippet:

try {
	$this->foo();
} catch (Exception $e) {
	// Is this the general exception all exceptions must extend from? Or Exception from the current namespace?
}

All references to types named Exception or ending with Exception must be referenced via a fully qualified name:

try {
	$this->foo();
} catch (\FooCurrentNamespace\Exception $e) {

} catch (\Exception $e) {

}

Sniff provides the following settings:

• Exceptions with different names can be configured in specialExceptionNames property.
• If your codebase uses classes that look like exceptions (because they have Exception or Error suffixes) but aren't, you can add them to ignoredNames property and the sniff won't enforce them to be fully qualified. Classes with Error suffix have to be added to ignored only if they are in the root namespace (like LibXMLError).

SlevomatCodingStandard.Namespaces.FullyQualifiedGlobalConstants 🔧

All references to global constants must be referenced via a fully qualified name.

Sniff provides the following settings:

• include: list of global constants that must be referenced via FQN. If not set all constants are considered.
• exclude: list of global constants that are allowed not to be referenced via FQN.

SlevomatCodingStandard.Namespaces.FullyQualifiedGlobalFunctions 🔧

All references to global functions must be referenced via a fully qualified name.

Sniff provides the following settings:

• include: list of global functions that must be referenced via FQN. If not set all functions are considered.
• includeSpecialFunctions: include complete list of PHP internal functions that could be optimized when referenced via FQN.
• exclude: list of global functions that are allowed not to be referenced via FQN.

SlevomatCodingStandard.Namespaces.FullyQualifiedClassNameInAnnotation 🔧

Enforces fully qualified names of classes and interfaces in phpDocs - in annotations. This results in unambiguous phpDocs.

Sniff provides the following settings:

• ignoredAnnotationNames: case-sensitive list of annotation names that the sniff should ignore. Useful for custom annotation names like @apiParam

SlevomatCodingStandard.Namespaces.MultipleUsesPerLine

Prohibits multiple uses separated by commas:

use Foo, Bar;

SlevomatCodingStandard.Namespaces.NamespaceDeclaration 🔧

Enforces one space after namespace, disallows content between namespace name and semicolon and disallows use of bracketed syntax.

SlevomatCodingStandard.Namespaces.NamespaceSpacing 🔧

Enforces configurable number of lines before and after namespace.

Sniff provides the following settings:

• linesCountBeforeNamespace: allows to configure the number of lines before namespace.
• linesCountAfterNamespace: allows to configure the number of lines after namespace.

SlevomatCodingStandard.Namespaces.RequireOneNamespaceInFile

Requires only one namespace in a file.

SlevomatCodingStandard.Namespaces.ReferenceUsedNamesOnly 🔧

Sniff provides the following settings:

• searchAnnotations (defaults to false): enables searching for mentions in annotations.
• namespacesRequiredToUse: if not set, all namespaces are required to be used. When set, only mentioned namespaces are required to be used. Useful in tandem with UseOnlyWhitelistedNamespaces sniff.
• allowFullyQualifiedExceptions, specialExceptionNames & ignoredNames: allows fully qualified exceptions. Useful in tandem with FullyQualifiedExceptions sniff.
• allowFullyQualifiedNameForCollidingClasses: allow fully qualified name for a class with a colliding use statement.
• allowFullyQualifiedNameForCollidingFunctions: allow fully qualified name for a function with a colliding use statement.
• allowFullyQualifiedNameForCollidingConstants: allow fully qualified name for a constant with a colliding use statement.
• allowFullyQualifiedGlobalClasses: allows using fully qualified classes from global space (i.e. \DateTimeImmutable).
• allowFullyQualifiedGlobalFunctions: allows using fully qualified functions from global space (i.e. \phpversion()).
• allowFullyQualifiedGlobalConstants: allows using fully qualified constants from global space (i.e. \PHP_VERSION).
• allowFallbackGlobalFunctions: allows using global functions via fallback name without use (i.e. phpversion()).
• allowFallbackGlobalConstants: allows using global constants via fallback name without use (i.e. PHP_VERSION).
• allowPartialUses: allows using and referencing whole namespaces.

SlevomatCodingStandard.Namespaces.UseFromSameNamespace 🔧

Sniff prohibits uses from the same namespace:

namespace Foo;

use Foo\Bar;

SlevomatCodingStandard.Namespaces.UseDoesNotStartWithBackslash 🔧

Disallows leading backslash in use statement:

use \Foo\Bar;

SlevomatCodingStandard.Namespaces.UseSpacing 🔧

Enforces configurable number of lines before first use, after last use and between two different types of use (eg. between use function and use const). Also enforces zero number of lines between same types of use.

Sniff provides the following settings:

• linesCountBeforeFirstUse: allows to configure the number of lines before first use.
• linesCountBetweenUseTypes: allows to configure the number of lines between two different types of use.
• linesCountAfterLastUse: allows to configure the number of lines after last use.

SlevomatCodingStandard.Namespaces.UseOnlyWhitelistedNamespaces

Sniff disallows uses of other than configured namespaces.

Sniff provides the following settings:

• namespacesRequiredToUse: namespaces in this array are the only ones allowed to be used. E.g. root project namespace.
• allowUseFromRootNamespace: also allow using top-level namespace:

use DateTimeImmutable;

SlevomatCodingStandard.Namespaces.UselessAlias 🔧

Looks for use alias that is same as unqualified name.

SlevomatCodingStandard.Namespaces.UnusedUses 🔧

Looks for unused imports from other namespaces.

Sniff provides the following settings:

• searchAnnotations (defaults to false): enables searching for class names in annotations.
• ignoredAnnotationNames: case-sensitive list of annotation names that the sniff should ignore (only the name is ignored, annotation content is still searched). Useful for name collisions like @testCase annotation and TestCase class.
• ignoredAnnotations: case-sensitive list of annotation names that the sniff ignore completely (both name and content are ignored). Useful for name collisions like @group Cache annotation and Cache class.
