Php 如何预分割方括号并将其分组到数组中

我有一个用PHP读取的.ini文件，我想把它们转换成多维数组

输入：

[101]
DestName=Person A
dstaddr=+880071268
smbody=This Is Testing 1
response=http://localhost/reply.php
[102]
DestName=Person B
dstaddr=+890071268
smbody=This Is Testing 2
[103]
.
.
.

[
 "101": [
     DestName: "Person A"
     dstaddr: "+880071268"
     response: "http://localhost/reply.php"
     smbody: "This Is Testing 1"
    ]
 "102": [
     DestName: "Person B"
     dstaddr: "+890071268"
     smbody: "This Is Testing 2"
    ]
]

[
 0: [
     DestName: "Person A"
     dstaddr: "+880071268"
     response: "http://localhost/reply.php"
     smbody: "This Is Testing 1"
    ]
 1: [
     DestName: "Person B"
     dstaddr: "+890071268"
     smbody: "This Is Testing 2"
    ]
]

我想用正则表达式preg_split从中得到一个数组：

预期产出：

[101]
DestName=Person A
dstaddr=+880071268
smbody=This Is Testing 1
response=http://localhost/reply.php
[102]
DestName=Person B
dstaddr=+890071268
smbody=This Is Testing 2
[103]
.
.
.

[
 "101": [
     DestName: "Person A"
     dstaddr: "+880071268"
     response: "http://localhost/reply.php"
     smbody: "This Is Testing 1"
    ]
 "102": [
     DestName: "Person B"
     dstaddr: "+890071268"
     smbody: "This Is Testing 2"
    ]
]

[
 0: [
     DestName: "Person A"
     dstaddr: "+880071268"
     response: "http://localhost/reply.php"
     smbody: "This Is Testing 1"
    ]
 1: [
     DestName: "Person B"
     dstaddr: "+890071268"
     smbody: "This Is Testing 2"
    ]
]

我已经阅读了这里的一些答案，并尝试了下面的代码以获得其他输出

$num = preg_split("#\[[^\]]+\]\r\n#", $fread, NULL, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);

foreach ($num as $skey => $str){
    foreach (explode("\r\n", $str) as $key => $line) {
        $l = explode('=', trim($line));
        if (isset($l[1])){
            $arr[$skey][$l[0]] = $l[1];
        }
    }
}

我的输出：

[101]
DestName=Person A
dstaddr=+880071268
smbody=This Is Testing 1
response=http://localhost/reply.php
[102]
DestName=Person B
dstaddr=+890071268
smbody=This Is Testing 2
[103]
.

[
 "101": [
     DestName: "Person A"
     dstaddr: "+880071268"
     response: "http://localhost/reply.php"
     smbody: "This Is Testing 1"
    ]
 "102": [
     DestName: "Person B"
     dstaddr: "+890071268"
     smbody: "This Is Testing 2"
    ]
]

[
 0: [
     DestName: "Person A"
     dstaddr: "+880071268"
     response: "http://localhost/reply.php"
     smbody: "This Is Testing 1"
    ]
 1: [
     DestName: "Person B"
     dstaddr: "+890071268"
     smbody: "This Is Testing 2"
    ]
]

请注意，我无法获取方括号内的值（例如[101]中的101）并将其转换为数组的键。

只使用内置的：
