arrayDiffAssocRecursive()

static TYPO3\CMS\Core\Utility\ArrayUtility::arrayDiffAssocRecursive ( array  $array1, array  $array2  )

static

Filters keys off from first array that also exist in second array. Comparison is done by keys. This method is a recursive version of php array_diff_assoc()

Parameters

array	$array1	Source array
array	$array2	Reduce source array by this array

Returns

array Source array reduced by keys also present in second array

arrayExport()

static TYPO3\CMS\Core\Utility\ArrayUtility::arrayExport ( array  $array = [],   $level = 0  )

static

Exports an array as string. Similar to var_export(), but representation follows the PSR-2 and TYPO3 core CGL.

See unit tests for detailed examples

Parameters

array	$array	Array to export
int	$level	Internal level used for recursion, do not set from outside!

Returns

string String representation of array

filterByValueRecursive()

static TYPO3\CMS\Core\Utility\ArrayUtility::filterByValueRecursive (   $needle = '', array  $haystack = []  )

static

Reduce an array by a search value and keep the array structure.

Comparison is type strict:

• For a given needle of type string, integer, array or boolean, value and value type must match to occur in result array
• For a given object, an object within the array must be a reference to the same object to match (not just different instance of same class)

Example:

• Needle: 'findMe'
• Given array: array( 'foo' => 'noMatch', 'bar' => 'findMe', 'foobar => array( 'foo' => 'findMe', ), );
• Result: array( 'bar' => 'findMe', 'foobar' => array( 'foo' => findMe', ), );

See the unit tests for more examples and expected behaviour

Parameters

mixed	$needle	The value to search for
array	$haystack	The array in which to search

Returns

array $haystack array reduced matching $needle values

flatten()

static TYPO3\CMS\Core\Utility\ArrayUtility::flatten ( array  $array,   $prefix = ''  )

static

Converts a multidimensional array to a flat representation.

See unit tests for more details

Example:

• array: array( 'first.' => array( 'second' => 1 ) )
• result: array( 'first.second' => 1 )

Example:

• array: array( 'first' => array( 'second' => 1 ) )
• result: array( 'first.second' => 1 )

Parameters

array	$array	The (relative) array to be converted
string	$prefix	The (relative) prefix to be used (e.g. 'section.')

Returns

array

Example

• array: array( 'foo' => array( 'bar' => array( 'baz' => 42 ) ) );

inArray()

static TYPO3\CMS\Core\Utility\ArrayUtility::inArray ( array  $in_array,   $item  )

static

Check if an string item exists in an array. Please note that the order of function parameters is reverse compared to the PHP function in_array()!!!

Comparison to PHP in_array(): -> $array = array(0, 1, 2, 3); -> variant_a := ::inArray($array, $needle) -> variant_b := in_array($needle, $array) -> variant_c := in_array($needle, $array, TRUE) +------—+--------—+--------—+--------—+ | $needle | variant_a | variant_b | variant_c | +------—+--------—+--------—+--------—+ | '1a' | FALSE | TRUE | FALSE | | '' | FALSE | TRUE | FALSE | | '0' | TRUE | TRUE | FALSE | | 0 | TRUE | TRUE | TRUE | +------—+--------—+--------—+--------—+

Parameters

array	$in_array	One-dimensional array of items
string	$item	Item to check for

Returns

bool TRUE if $item is in the one-dimensional array $in_array

intersectRecursive()

static TYPO3\CMS\Core\Utility\ArrayUtility::intersectRecursive ( array  $source, array  $mask = []  )

static

Determine the intersections between two arrays, recursively comparing keys A complete sub array of $source will be preserved, if the key exists in $mask.

See unit tests for more examples and edge cases.

Example:

• source: array( 'key1' => 'bar', 'key2' => array( 'subkey1' => 'sub1', 'subkey2' => 'sub2', ), 'key3' => 'baz', )
• mask: array( 'key1' => NULL, 'key2' => array( 'subkey1' => exists', ), )
• return: array( 'key1' => 'bar', 'key2' => array( 'subkey1' => 'sub1', ), )

Parameters

array	$source	Source array
array	$mask	Array that has the keys which should be kept in the source array

Returns

array Keys which are present in both arrays with values of the source array

keepItemsInArray()

static TYPO3\CMS\Core\Utility\ArrayUtility::keepItemsInArray ( array  $array,   $keepItems,   $getValueFunc = null  )

static

Example (arguments used to call this function): $array = array( array('aa' => array('first', 'second'), array('bb' => array('third', 'fourth'), array('cc' => array('fifth', 'sixth'), ); $keepItems = array('third'); $getValueFunc = function($value) { return $value[0]; }

Returns: array( array('bb' => array('third', 'fourth'), )

Parameters

array	$array	The initial array to be filtered/reduced
mixed	$keepItems	The items which are allowed/kept in the array - accepts array or csv string
string	$getValueFunc	(optional) Callback function used to get the value to keep

Returns

array The filtered/reduced array with the kept items

mergeRecursiveWithOverrule()

static TYPO3\CMS\Core\Utility\ArrayUtility::mergeRecursiveWithOverrule ( array &  $original, array  $overrule,   $addKeys = true,   $includeEmptyValues = true,   $enableUnsetFeature = true  )

static

Merges two arrays recursively and "binary safe" (integer keys are overridden as well), overruling similar values in the original array with the values of the overrule array. In case of identical keys, ie. keeping the values of the overrule array.

This method takes the original array by reference for speed optimization with large arrays

The differences to the existing PHP function array_merge_recursive() are:

• Keys of the original array can be unset via the overrule array. ($enableUnsetFeature)
• Much more control over what is actually merged. ($addKeys, $includeEmptyValues)
• Elements or the original array get overwritten if the same key is present in the overrule array.

Parameters

array	$original	Original array. It will be modified by this method and contains the result afterwards!
array	$overrule	Overrule array, overruling the original array
bool	$addKeys	If set to FALSE, keys that are NOT found in $original will not be set. Thus only existing value can/will be overruled from overrule array.
bool	$includeEmptyValues	If set, values from $overrule will overrule if they are empty or zero.
bool	$enableUnsetFeature	If set, special values "__UNSET" can be used in the overrule array in order to unset array keys in the original array.

Returns

void
