Properties

$exclude

Exclude groups.

public array<string|int, mixed> $exclude = array()

Example: 'switch_to_blog,user_meta'

1.0.0

This property now expects to be passed an array. Previously a comma-delimited string was expected.

$unittest_groups

Groups of function data to check against.

public static array<string|int, mixed> $unittest_groups = array()

Don't use this in extended classes, override getGroups() instead. This is only used for Unit tests.

$group_name

The group name for this group of functions.

protected string $group_name = 'restricted_parameters'

Intended to be overruled in the child class.

$phpcsFile

The current file being sniffed.

protected File $phpcsFile
Tags
since
0.4.0

$target_functions

Functions this sniff is looking for. Should be defined in the child class.

protected array<string|int, mixed> $target_functions = array()

The only requirement for this array is that the top level array keys are the names of the functions you're looking for. Other than that, the array can have arbitrary content depending on your needs.

$tokens

The list of tokens in the current file being sniffed.

protected array<string|int, mixed> $tokens
Tags

0.4.0

Methods

check_for_matches()

Verify if the current token is one of the targetted functions.

public check_for_matches(int $stackPtr) : int|void
Parameters
$stackPtr : int

The position of the current token in the stack.

Tags
since
0.11.0

Split out from the process() method.

Return values
int|void —

Integer stack pointer to skip forward or void to continue normal file processing.

getGroups()

Groups of functions to restrict.

public getGroups() : array<string|int, mixed>
Return values
array<string|int, mixed>

is_targetted_token()

Verify is the current token is a function call.

public is_targetted_token(int $stackPtr) : bool
Parameters
$stackPtr : int

The position of the current token in the stack.

Tags
since
0.11.0

Split out from the process() method.

Return values
bool

process()

Set sniff properties and hand off to child class for processing of the token.

public process(File $phpcsFile, int $stackPtr) : int|void
Parameters
$phpcsFile : File

The file being scanned.

$stackPtr : int

The position of the current token in the stack passed in $tokens.

Tags
since
0.11.0
Return values
int|void —

Integer stack pointer to skip forward or void to continue normal file processing.

process_matched_token()

Process a matched token.

public process_matched_token(int $stackPtr, string $group_name, string $matched_content) : int|void
Parameters
$stackPtr : int

The position of the current token in the stack.

$group_name : string

The name of the group which was matched.

$matched_content : string

The token content (function name) which was matched in lowercase.

Return values
int|void —

Integer stack pointer to skip forward or void to continue normal file processing.

process_no_parameters()

Process the function if no parameters were found.

public process_no_parameters(int $stackPtr, string $group_name, string $matched_content) : int|void

Defaults to doing nothing. Can be overloaded in child classes to handle functions were parameters are expected, but none found.

Parameters
$stackPtr : int

The position of the current token in the stack.

$group_name : string

The name of the group which was matched.

$matched_content : string

The token content (function name) which was matched in lowercase.

Return values
int|void —

Integer stack pointer to skip forward or void to continue normal file processing.

process_parameters()

Process the parameters of a matched function.

public abstract process_parameters(int $stackPtr, string $group_name, string $matched_content, array<string|int, mixed> $parameters) : int|void

This method has to be made concrete in child classes.

Parameters
$stackPtr : int

The position of the current token in the stack.

$group_name : string

The name of the group which was matched.

$matched_content : string

The token content (function name) which was matched in lowercase.

$parameters : array<string|int, mixed>

Array with information about the parameters.

Return values
int|void —

Integer stack pointer to skip forward or void to continue normal file processing.

process_token()

Processes this test, when one of its tokens is encountered.

public process_token(int $stackPtr) : int|void
Parameters
$stackPtr : int

The position of the current token in the stack.

Return values
int|void —

Integer stack pointer to skip forward or void to continue normal file processing.

register()

Returns an array of tokens this test wants to listen for.

public register() : array<string|int, mixed>
Return values
array<string|int, mixed>

prepare_name_for_regex()

Prepare the function name for use in a regular expression.

protected prepare_name_for_regex(string $function_name) : string

The getGroups() method allows for providing function names with a wildcard * to target a group of functions. This prepare routine takes that into account while still safely escaping the function name for use in a regular expression.

Parameters
$function_name : string

Function name.

Tags
since
0.10.0
Return values
string —

Regex escaped function name.

setup_groups()

Set up the regular expressions for each group.

protected setup_groups(string $key) : bool
Parameters
$key : string

The group array index key where the input for the regular expression can be found.

Tags
since
0.10.0
Return values
bool —

True if the groups were setup. False if not.
