正则请教

简单的实现方式，看下是否符合你的需求。

$result = [];
parse_str(str_replace('#', '&', $str), $result);

感觉这个应该需要先确定字段吧，不然又怎么能确定dl现在不是等于这个呢

两个思路

1. 确定格式吧 然后匹配
2. 把val值使用url转码一下 ['brid' => "xx#aaa=yy"] 地址就是 brid=xx%23aaa%3dyy

• 代码

<?php
$str = 'si@anyunlock/download-ios.htm#pid=au#lid=year#os=mobile#brid=sf#bid=0#dl=product/index.htm#ld=anytransweb/?token=00ed9f66#/index#limitFeature=xq41tr3_50080125314367-ly42ve3_92890225314335#fromApi=true#pwdType=oderdeid#featureNo=mdm#currentFeature=mdm#coupon=MOBI62#oid=908505173';
$regex = '/(?:#|&)([^#=]+)=([^&#]+)/';
preg_match_all($regex, $str, $matches);
print_r($matches);

• 结果

Array

    [0] => Array
        (
            [0] => #pid=au
            [1] => #lid=year
            [2] => #os=mobile
            [3] => #brid=sf
            [4] => #bid=0

        )

            [13] => oid
        )

    [2] => Array
        (
            [0] => au
            [1] => year

            [12] => MOBI62
            [13] => 908505173
        )

)

不好意思,看下这回呢

<?php

$str = 'si@anyunlock/download-ios.htm#pid=au#lid=year#os=mobile#brid=sf#bid=0#dl=product/index.htm#ld=anytransweb/?token=00ed9f66#/index#limitFeature=xq41tr3_50080125314367-ly42ve3_92890225314335#fromApi=true#pwdType=oderdeid#featureNo=mdm#currentFeature=mdm#coupon=MOBI62#oid=908505173';

// 定义正则表达式模式
$pattern = '/#(\w+)=([^#&]+)/';

// 使用正则表达式匹配参数
preg_match_all($pattern, $str, $matches);

// 组装匹配结果为关联数组
$result = array_combine($matches[1], $matches[2]);

// 打印结果
print_r($result);

这段代码的正则表达式 #(\w+)=([^#&]+) 的解释如下：

• #：匹配字符 “#”。
• (\w+)：捕获一个或多个单词字符，即参数的键。
• =：匹配等号。
• ([^#&]+)：捕获一个或多个不包含 “#” 和 “&” 的字符，即参数的值。

这样，通过 preg_match_all 函数，我们可以将匹配到的键值对组合成关联数组，并打印出结果。在你提供的例子中，这段代码会输出符合你期望的关联数组。在给定的示例字符串中，使用提供的 PHP 代码，输出的结果将是如下的关联数组：

Array
(
    [pid] => au
    [lid] => year
    [os] => mobile
    [brid] => sf
    [bid] => 0
    [dl] => product/index.htm
    [ld] => anytransweb/?token=00ed9f66
    [limitFeature] => xq41tr3_50080125314367-ly42ve3_92890225314335
    [fromApi] => true
    [pwdType] => oderdeid
    [featureNo] => mdm
    [currentFeature] => mdm
    [coupon] => MOBI62
    [oid] => 908505173
)

这个关联数组包含了从字符串中提取的各个参数及其对应的值。参数的键是数组的键，而参数的值是数组的值。

<?php
$str = 'si@anyunlock/download-ios.htm#pid=au#lid=year#os=mobile#brid=sf#bid=0#dl=product/index.htm#ld=anytransweb/?token=00ed9f66#/index#limitFeature=xq41tr3_50080125314367-ly42ve3_92890225314335#fromApi=true#pwdType=oderdeid#featureNo=mdm#currentFeature=mdm#coupon=MOBI62#oid=908505173';

// 使用正则表达式匹配键值对
preg_match_all('/([^#=]+)=([^#]+(?=#|$))/', $str, $matches);

$result = array_combine($matches[1], $matches[2]);

print_r($result);

//打印结果
Array

    [pid] => au
    [lid] => year
    [os] => mobile

    [bid] => 0
    [dl] => product/index.htm
    [ld] => anytransweb/?token=00ed9f66
    [limitFeature] => xq41tr3_50080125314367-ly42ve3_92890225314335
    [fromApi] => true
    [pwdType] => oderdeid
    [featureNo] => mdm
    [currentFeature] => mdm
    [coupon] => MOBI62
    [oid] => 908505173
)

#\w+=[\w\/\.]+(\?\w+=\w+\#\/\w+)*

(?<=#)[^=]+=([^#]|#\/)+
