如何使用PHP获取基于字符串起点和终点的特定信息

我有以下资料：

[38] => href="/wiki/Adventure_(Bookshelf)"
[39] => href="/wiki/Africa_(Bookshelf)"
[40] => href="/wiki/African_American_Writers_(Bookshelf)"

现在，我只想得到这个数组：

[13] => Agriculture_Bookshelf
[14] => Animal
[15] => Children%27s_Bookshelf
[16] => Classics_Bookshelf
[17] => Countries_Bookshelf
[18] => Crime_Bookshelf
[19] => Education_Bookshelf
[20] => Fine_arts_Bookshelf
[21] => General_Works_Bookshelf
[22] => Geography_Bookshelf
[23] => Health_Bookshelf
[24] => History_Bookshelf
[25] => Language_and_Literature_Bookshelf
[26] => Law_Bookshelf
[27] => Library_Science
[28] => Music_Bookshelf
[29] => Periodicals_Bookshelf
[30] => Political_Science_Bookshelf
[31] => Psychology_and_Philosophy_Bookshelf
[32] => Religion_Bookshelf
[33] => Science_Bookshelf
[34] => Social_Sciences_Bookshelf
[35] => Technology_Bookshelf
[36] => Wars_Bookshelf

我正在使用这段代码获得上述结果，但仍然没有运气

$match[0]

包含上述数组

$str = '_Bookshelf';  
if(in_array($str,$match[0])){
    echo "FOUND!!";
    foreach($match[0] as $asd=>$asds){
        echo "<pre>";echo str_replace('href="/wiki/Category:','',$asds);echo "</pre>";
        }
    }

$str=''u书架'；
if（在数组中（$str，$match[0]））{
回声“找到了！！”；
foreach（$asd=>$asd时匹配[0]{
echo”“；echo str_replace（'href=“/wiki/Category:”，''$asds）；echo”“；
}
}

请修改我的代码以获得所需的结果。

使用正则表达式测试模式的URL

---

in_array（）

查找精确匹配，而不是子字符串，因此第一个

if

将无法成功使用上述数组。谢谢，请您更正所需结果。第一类代码，第一类。但我在最后一个中有

“

类似：

战争书架“类别”书架第二：我不想要这些：
DE_B%C3%BCcherregal“FR_体裁”IT_Biblioteca“PT_pratelera”
和
Categories“Bookshelf”Categories“DE_B%C3%BCcherregal”FR_体裁“IT_Biblioteca”PT_pratelera“
我没有注意到值中的引号（我以为他们只是PHP引用了
var_dump
output中的字符串），我修复了regexp以返回结束引号之前的部分。它不会返回
DE_B%C3%BCcherregal
，因为它不会以
\u Bookshelf结尾。”
。您好，您注意到了吗，您在数组中遗漏了
动物
和
图书馆学
？请重新检查您的代码。我也需要它们在数组中，因为我的问题是要包括开始
\u书架
和结束
\u书架
中的所有内容。只需将
\u书架之间的所有类别包含在内e> 作为开始，作为结束。我指的是一种范围。类似的。
// Find the first _Bookshelf element
foreach ($match[0] as $key => $value) {
    if (preg_match('#/wiki/Category:(.*_Bookshelf)"$#', $value)) {
        $first_index = $key;
        break;
    }
}
// Find the last _Bookshelf element by searching the reversed array
foreach (array_reverse($match[0]) as $key => $value) {
    if (preg_match('#/wiki/Category:(.*_Bookshelf)"$#', $value)) {
        $last_index = $key;
        break;
    }
}
// Get the selected part of the array
$result = array_slice($match[0], $first_index, -$last_index);
// Remove the URL prefix and quote at the end
foreach ($result as &$val) {
    $val = preg_replace('#.*/wiki/Category:(.*)"$#', '$1', $val);
}
