从网址中选择搜索查询

Question

Here's what I have so far:

preg_match('/[q|p]=(.*?)&/',$url,$query);

The problem is that if there's a param that ends with a q or p, the it will include those:

&cap=queryhere

since cap ends with p it includes those, how can I only include search queries that come from q's and p's only. Thanks!

Answer 1

you don't need to use regular expressions, php has built in functions to work with type of information, it is more accurate.

<?php

$url = "http://mysite.com/page.php?q=this is my query&a=123";

$query = parse_url($url, PHP_URL_QUERY);

parse_str($query, $opt);

print_r($opt);

outputs:

Array
(
    [q] => this is my query
    [a] => 123
)
