(PHP 8 >= 8.4.0)

array_any — Checks if at least one array element satisfies a callback function

Description

array_any() returns true, if the given callback returns true for any element. Otherwise the function returns false.

Parameters

array
The array that should be searched.
callback

The callback function to call to check each element, which must be

If this function returns true, true is returned from array_any() and the callback will not be called for further elements.

Return Values

The function returns true, if there is at least one element for which callback returns true. Otherwise the function returns false.

Examples

Example #1 array_any() example

<?php
$array = [
'a' => 'dog',
'b' => 'cat',
'c' => 'cow',
'd' => 'duck',
'e' => 'goose',
'f' => 'elephant'
];// Check, if any animal name is longer than 5 letters.
var_dump(array_any($array, function (string $value) {
return strlen($value) > 5;
}));// Check, if any animal name is shorter than 3 letters.
var_dump(array_any($array, function (string $value) {
return strlen($value) < 3;
}));// Check, if any array key is not a string.
var_dump(array_any($array, function (string $value, $key) {
return !is_string($key);
}));
?>

The above example will output:

bool(true)
bool(false)
bool(false)

This can be a replacement for array_filter() where an existence check is the only purpose. But, unlike array_filter(), the callback always requires two arguments. There's no way to change this, so some a lot of old-fashioned string callables are no longer usable.

<?php
$arr = [45, 'abc', 'def', 'ghi'];

if (array_filter($arr, 'is_integer')) {
    // works because of loose comparison: [45] == true
}

if (array_any($arr, 'is_integer')) {
    // PHP Warning:  Uncaught ArgumentCountError: is_integer() expects exactly 1 argument, 2 given
}
?>
