PHP - Manual: array_all

2025-04-27

array_all

(PHP 8 >= 8.4.0)

array_allChecks if all array elements satisfy a callback function

说明

array_all(array $array, callable $callback): bool

array_all() returns true, if the given callback returns true for all elements. Otherwise the function returns false.

参数

array
The array that should be searched.
callback

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

callback(mixed $value, mixed $key): bool
If this function returns false, false is returned from array_all() and the callback will not be called for further elements.

返回值

The function returns true, if callback returns true for all elements. Otherwise the function returns false.

示例

示例 #1 array_all() example

<?php
$array
= [
'a' => 'dog',
'b' => 'cat',
'c' => 'cow',
'd' => 'duck',
'e' => 'goose',
'f' => 'elephant'
];

// Check, if all animal names are shorter than 12 letters.
var_dump(array_all($array, function (string $value) {
return
strlen($value) < 12;
}));

// Check, if all animal names are longer than 5 letters.
var_dump(array_all($array, function (string $value) {
return
strlen($value) > 5;
}));

// Check, if all array keys are strings.
var_dump(array_all($array, function (string $value, $key) {
return
is_string($key);
}));
?>

以上示例会输出:

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