php - ini 文件中的嵌套数组

Question

我试图在 ini 设置文件中有一个嵌套的数组结构。我的结构是：

stuct1[123][a] = "1"
stuct1[123][b] = "2"
stuct1[123][c] = "3"
stuct1[123][d] = "4"

但这不起作用。谁能解释这种类型的结构是否可行parse_ini_file

如果可能的话，我做错了什么？

Answer 1

您可以使用该任务的部分功能parse_ini_file。

请务必将第二个参数设置为true：

parse_ini_file("sample.ini", true);

创建子部分并不完全可能，但您可以像这样创建索引子数组：

[123]
setting[] = "1"
setting[] = "2"
setting[] = "3"
setting[] = "4"

解析它看起来像thos

[123][setting][0] => "1"
[123][setting][1] => "2"
[123][setting][2] => "3"
[123][setting][3] => "4"

Answer 2

您最多可以创建三个级别。

<?php

define('BIRD', 'Dodo bird');

$ini_array = parse_ini_file("sample.ini", true);
echo '<pre>'.print_r($ini_array,true).'</pre>';

?>

parse_ini_file.ini

; This is a sample configuration file
; Comments start with ';', as in php.ini

[first_section]
one = 1
five = 5
animal = BIRD

[second_section]
path = "/usr/local/bin"
URL = "http://www.example.com/~username"
second_section[one] = "1 associated"
second_section[two] = "2 associated"
second_section[] = "1 unassociated"
second_section[] = "2 unassociated"

[third_section]
phpversion[] = "5.0"
phpversion[] = "5.1"
phpversion[] = "5.2"
phpversion[] = "5.3"

输出

Array (

    [first_section] => Array (
        [one] => 1
        [five] => 5
        [animal] => Dodo bird
    )

    [second_section] => Array (
        [path] => /usr/local/bin
        [URL] => http://www.example.com/~username
        [second_section] => Array (
            [one] => 1 associated
            [two] => 2 associated
            [0] => 1 unassociated
            [1] => 2 unassociated
        )
    )

    [third_section] => Array (
        [phpversion] => Array (
            [0] => 5.0
            [1] => 5.1
            [2] => 5.2
            [3] => 5.3
        )
    )
    
)

Answer 3

INI 文件非常有限，并且 parse_ini_file 远非完美。如果你有这样的要求，你最好寻找一些其他的语法。

那么JSON呢？它在 PHP 中的支持带来了几乎相同的舒适度：

$data = json_decode(file_get_contents($filename), TRUE);
file_put_contents($filename, json_encode($data));

Answer 4

这是在 ini 中对值进行分组的另一种方法：

我的.ini：

[singles] 
test = a test 
test2 = another test 
test3 = this is a test too

[multiples] 
tests[] = a test 
tests[] = another 
test tests[] = this is a test too

我的.php：

与以下相同：

<?php 
$init['test'] = 'a test';
$init['test2'] = 'another test';
$init['test3'] = 'this is a test too';
$init['tests'][0] = 'a test';
$init['tests'][1] = 'another test';
$init['tests'][2] = 'this is a
test too'; ?>

这也适用于 bool 设置为 true ，可用于循环。也适用于设置为 true 的 bool。
