Web-PHP

PHP / array_diff_uassoc — DevDocs

array_diff_uassoc

(PHP 5, PHP 7, PHP 8)

array_diff_uassoc — Computes the difference of arrays with additional index check which is performed by a user supplied callback function

Description

array_diff_uassoc(array $array, array ...$arrays, callable $key_compare_func): array

Compares array against arrays and returns the difference. Unlike array_diff() the array keys are used in the comparison.

Unlike array_diff_assoc() a user supplied callback function is used for the indices comparison, not internal function.

Parameters

array

The array to compare from

arrays

Arrays to compare against

key_compare_func

The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

callback(mixed $a, mixed $b): int

Return Values

Returns an array containing all the entries from array that are not present in any of the other arrays.

Examples

Example #1 array_diff_uassoc() example

The "a" => "green" pair is present in both arrays and thus it is not in the output from the function. Unlike this, the pair 0 => "red" is in the output because in the second argument "red" has key which is 1 .

<?php
function key_compare_func($a, $b)
{
    if ($a === $b) {
        return 0;
    }
    return ($a > $b)? 1:-1;
}

$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "green", "yellow", "red");
$result = array_diff_uassoc($array1, $array2, "key_compare_func");
print_r($result);
?>

The above example will output:

Array
(
    [b] => brown
    [c] => blue
    [0] => red
)

The equality of 2 indices is checked by the user supplied callback function.

Notes

Note :

This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using, for example, array_diff_uassoc($array1[0], $array2[0], "key_compare_func"); .

PHP / array_diff_ukey — DevDocs

array_diff_ukey

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

array_diff_ukey — Computes the difference of arrays using a callback function on the keys for comparison

Description

array_diff_ukey(array $array, array ...$arrays, callable $key_compare_func): array

Compares the keys from array against the keys from arrays and returns the difference. This function is like array_diff() except the comparison is done on the keys instead of the values.

Unlike array_diff_key() a user supplied callback function is used for the indices comparison, not internal function.

Parameters

array

The array to compare from

arrays

Arrays to compare against

key_compare_func

The comparison function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

callback(mixed $a, mixed $b): int

Return Values

Returns an array containing all the entries from array that are not present in any of the other arrays.

Examples

Example #1 array_diff_ukey() example

<?php
function key_compare_func($key1, $key2)
{
    if ($key1 == $key2)
        return 0;
    else if ($key1 > $key2)
        return 1;
    else
        return -1;
}

$array1 = array('blue'  => 1, 'red'  => 2, 'green'  => 3, 'purple' => 4);
$array2 = array('green' => 5, 'blue' => 6, 'yellow' => 7, 'cyan'   => 8);

var_dump(array_diff_ukey($array1, $array2, 'key_compare_func'));
?>

The above example will output:

array(2) {
  ["red"]=>
  int(2)
  ["purple"]=>
  int(4)
}

Notes

Note :

This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using array_diff_ukey($array1[0], $array2[0], 'callback_func'); .

PHP / array_fill — DevDocs

array_fill

(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

array_fill — Fill an array with values

Description

array_fill(int $start_index, int $count, mixed $value): array

Fills an array with count entries of the value of the value parameter, keys starting at the start_index parameter.

Parameters

start_index

The first index of the returned array.

If start_index is negative, the first index of the returned array will be start_index and the following indices will start from zero prior to PHP 8.0.0; as of PHP 8.0.0, negative keys are incremented normally (see example).

count

Number of elements to insert. Must be greater than or equal to zero, and less than or equal to 2147483647 .

value

Value to use for filling

Return Values

Returns the filled array

Errors/Exceptions

Throws a ValueError if count is out of range.

Changelog

Version	Description
8.0.0	array_fill() now throws a ValueError if `count` is out of range; previously `E_WARNING` was raised, and the function returned `false` .

Examples

Example #1 array_fill() example

<?php
$a = array_fill(5, 6, 'banana');
print_r($a);
?>

The above example will output:

Array
(
    [5]  => banana
    [6]  => banana
    [7]  => banana
    [8]  => banana
    [9]  => banana
    [10] => banana
)

Example #2 array_fill() example with a negative start index

<?php
$a = array_fill(-2, 4, 'pear');
print_r($a);
?>

Output of the above example in PHP 7:

Array
(
    [-2] => pear
    [0] => pear
    [1] => pear
    [2] => pear
)

Output of the above example in PHP 8:

Array
(
    [-2] => pear
    [-1] => pear
    [0] => pear
    [1] => pear
)

Note that index -1 is not present prior to PHP 8.0.0.

Notes

See also the Arrays section of manual for a detailed explanation of negative keys.

PHP / array_filter — DevDocs

array_filter

(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)

array_filter — Filters elements of an array using a callback function

Description

array_filter(array $array, ?callable $callback = null, int $mode = 0): array

Iterates over each value in the array passing them to the callback function. If the callback function returns true , the current value from array is returned into the result array .

Array keys are preserved, and may result in gaps if the array was indexed. The result array can be reindexed using the array_values() function.

Parameters

array

The array to iterate over

callback

The callback function to use

If no callback is supplied, all empty entries of array will be removed. See empty() for how PHP defines empty in this case.

mode

Flag determining what arguments are sent to callback :

ARRAY_FILTER_USE_KEY - pass key as the only argument to callback instead of the value
ARRAY_FILTER_USE_BOTH - pass both value and key as arguments to callback instead of the value

Default is

which will pass value as the only argument to


       callback

instead.

Return Values

Returns the filtered array.

Changelog

Version	Description
8.0.0	`callback` is nullable now.
8.0.0	If `callback` expects a parameter to be passed by reference, this function will now emit an `E_WARNING` .

Examples

Example #1 array_filter() example

<?php
function odd($var)
{
    // returns whether the input integer is odd
    return $var & 1;
}

function even($var)
{
    // returns whether the input integer is even
    return !($var & 1);
}

$array1 = ['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5];
$array2 = [6, 7, 8, 9, 10, 11, 12];

echo "Odd :\n";
print_r(array_filter($array1, "odd"));
echo "Even:\n";
print_r(array_filter($array2, "even"));
?>

The above example will output:

Odd :
Array
(
    [a] => 1
    [c] => 3
    [e] => 5
)
Even:
Array
(
    [0] => 6
    [2] => 8
    [4] => 10
    [6] => 12
)

Example #2 array_filter() without callback

<?php

$entry = [
    0 => 'foo',
    1 => false,
    2 => -1,
    3 => null,
    4 => '',
    5 => '0',
    6 => 0,
];

print_r(array_filter($entry));
?>

The above example will output:

Array
(
    [0] => foo
    [2] => -1
)

Example #3 array_filter() with mode

<?php

$arr = ['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4];

var_dump(array_filter($arr, function($k) {
    return $k == 'b';
}, ARRAY_FILTER_USE_KEY));

var_dump(array_filter($arr, function($v, $k) {
    return $k == 'b' || $v == 4;
}, ARRAY_FILTER_USE_BOTH));
?>

The above example will output:

array(1) {
  ["b"]=>
  int(2)
}
array(2) {
  ["b"]=>
  int(2)
  ["d"]=>
  int(4)
}

Notes

Caution

If the array is changed from the callback function (e.g. element added, deleted or unset) the behavior of this function is undefined.

PHP / array_flip — DevDocs

array_flip

(PHP 4, PHP 5, PHP 7, PHP 8)

array_flip — Exchanges all keys with their associated values in an array

Description

array_flip(array $array): array

array_flip() returns an array in flip order, i.e. keys from array become values and values from array become keys.

Note that the values of array need to be valid keys, i.e. they need to be either int or string . A warning will be emitted if a value has the wrong type, and the key/value pair in question will not be included in the result .

If a value has several occurrences, the latest key will be used as its value, and all others will be lost.

Parameters

array: An array of key/value pairs to be flipped.

Return Values

Returns the flipped array.

Examples

Example #1 array_flip() example

<?php
$input = array("oranges", "apples", "pears");
$flipped = array_flip($input);

print_r($flipped);
?>

The above example will output:

Array
(
    [oranges] => 0
    [apples] => 1
    [pears] => 2
)

Example #2 array_flip() example : collision

<?php
$input = array("a" => 1, "b" => 1, "c" => 2);
$flipped = array_flip($input);

print_r($flipped);
?>

The above example will output:

Array
