Answer 1

<?php
$personas = [
    'Franz' => [
        'interests' => ['all'],
        'gender' => 'maskulin'
    ],
    'Sissi' => [
        'interests' => ['kitesurfing', 'tennis'],
        'gender' => 'feminin'
    ],
    'Egon' => [
        'interests' => ['kitesurfing', 'cinema'],
        'gender' => 'maskulin'
    ],
    'Maria' => [
        'interests' => ['cinema', 'soccer'],
        'gender' => 'feminin'
    ]
];
$interests = ['all', 'kitesurfing'];
$filtered = array_filter($personas, function($v) use ($interests) {
    return array_intersect($interests, $v['interests']);
});
var_export($filtered);

输出：

array (
    'Franz' => 
    array (
    'interests' => 
    array (
        0 => 'all',
    ),
    'gender' => 'maskulin',
    ),
    'Sissi' => 
    array (
    'interests' => 
    array (
        0 => 'kitesurfing',
        1 => 'tennis',
    ),
    'gender' => 'feminin',
    ),
    'Egon' => 
    array (
    'interests' => 
    array (
        0 => 'kitesurfing',
        1 => 'cinema',
    ),
    'gender' => 'maskulin',
