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

    Parameter-Liste

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

    Beispiel #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);
    }));
    ?>

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    bool(true)
