在php的字符串之间获取单词

I want to select specific words of an url. Let say I have an url localhost/index.php?exam=one&people=two

The question, how to get "one" and "two" with php? I was read preg_match function, but I still confuse with regulation expression pattern. thanks for advance

$query - parse_url('localhost/index.php?exam=one&people=two', PHP_URL_QUERY);
parse_str($query, $keys);

print_r(array_values($keys)); // <- what you want

But beware of magic quotes in PHP < 5.4, parse_str() is affected by this setting

$_GET['exam'] retrieves one

$_GET['people'] retrieves two

Those are called GET parameters. You can access them using php's hashed variable $_GET['param'].

In this case $_GET['exam'] would be equal to 'one'

Luckily PHP parses it for you!

Try:

echo $_GET['exam'];

to see how it works.

To help debug things, you might find:

print_r($_GET);

useful.

Use parse_url to access the query string of the URL. explode the query string on ampersands to get an array of name=value pairs and explode those parts on equal-signs to split them into name and value.

you have this in the url? Then you can use $_GET['exam'] and $_GET['people']. You can read more about this here

You can use parse_str(), like this:

$queryString = $_SERVER['QUERY_STRING'];
parse_str($queryString, $parsedQueryString);

print_r($parsedQueryString);
