获取所有以特定文本开头的$ _POST变量 [英] Get all $_POST variables starting with certain text

问题描述

我有一个html表单，其中有一个部分会生成带有随机名称的输入.

I have an html form with a section that generates inputs with random names.

每个输入名称的开头都是文本"book"，结尾是随机文本.

Each input name is generated with the text "book" at the beginning and random text at the end.

<input type="text" name="book_4552f" />
<input type="text" name="book_3507p" />
<input type="text" name="book_8031b" />

如何使用PHP获取以文本"book"开头的所有$ _POST变量?

How do I use PHP to get all $_POST variables which start with the text "book"?

推荐答案

以下内容使用 strpos()进行检查POST字符串以book_

The following uses strpos() to check that the POST string begins with book_

foreach($_POST as $key => $value) {
    if (strpos($key, 'book_') === 0) {
        // value starts with book_
    }
}
