如何在数组中逐字检索 $_GET 值
我有一个输入字段，提交时会在网址中附加这样的代码：
?searchval=this+is+a+test
在我的 php 文件中，我现在想逐字存储该字符串一个数组，在空格所在的地方分割它......像这样：
array[0] = "this";
array[1] = "is";
array[2] = "a";
array[3] = "test";
完成这个任务最有效的方法是什么？我已经搞乱了 substr() 和 preg_replace() 但整个事情非常混乱，我认为必须有一种更简单的方法，考虑到 $_GET 也在 URL 中用 + 分割单词。
任何帮助将不胜感激。 :)
I have an input field, that when submitted attaches a code like this to the url:
?searchval=this+is+a+test
In my php file I now want to store this string word by word in an array, splitting it where the spaces are... Something like this:
array[0] = "this";
array[1] = "is";
array[2] = "a";
array[3] = "test";
What would be the most effective way to accomplish this? I have messed around with substr() and preg_replace() but the whole thing is very messy and I figured that there must be an easier way, considering the $_GET also splits the words with +'s in the URL.
Any help would be greatly appreciated. :)

您正在寻找
explode。我应该在这里指出，虽然您可能会在 URL 中看到加号，但当填充
$_GET时，PHP 会自动将这些加号转换为空格。用技术术语来说，查询字符串变量的名称和值是 URL 解码的（这正是您也可以使用urldecode）。You are looking for
explode.I should note here that while you may see plus signs in the URL, these are automatically translated to spaces by PHP when
$_GETis populated. In technical terms, the names and values of the query string variables are URL-decoded (exactly what you can also do in code withurldecode).
