PHP：array_get关联数组取值实现类似Python字典默认取值的功能

# -*- coding: utf-8 -*-
data = {
    'name': 'Tom',
    'age': 23
}
print(data.get('name'))
# Tom
print(data.get('school'))
# None
print(data.get('school', 'puk'))
# puk

<?php
function array_get($array, $value, $default = null)
{
    return isset($array[$value]) ? $array[$value] : $default;
}

$data = [
    'name' => 'Tom',
    'age'  => 23
];
var_dump(array_get($data, 'name'));
// string(3) "Tom"
var_dump(array_get($data, 'school'));
// NULL
var_dump(array_get($data, 'school', 'puk'));
// string(3) "puk"
