如何 preg_split 方括号并将它们分组到数组中

Question

我有一个 .ini 文件要在 PHP 中读取，我想将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]
.
.
.

我想用正则表达式从中得到一个数组 preg_split:

预期输出:

[
 "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"
    ]
]

我已经从这里阅读了一些答案并尝试了如下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:

[
 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）并转换为我的数组的键。

使用内置的 parse_ini_file:

会容易得多

$result = parse_ini_file("myfile.ini", true)
