PHP中一个好用的函数parse_url,特别方便用来做信息抓取的分析,举例子如下:
$url = "http://www.electrictoolbox.com/php-extract-domain-from-full-url/"; $parts = parse_url($url);
输出:
Array ( [scheme] => http [host] => www.electrictoolbox.com [path] => /php-extract-domain-from-full-url/ )
又如:
<?php $url = ‘http://username:[email protected]/path?arg=value#anchor‘; print_r(parse_url($url)); echo parse_url($url, PHP_URL_PATH); ?>
输出:
Array ( [scheme] => http [host] => hostname [user] => username [pass] => password [path] => /path [query] => arg=value [fragment] => anchor )
可以看到,可以很容易分解出一个URL的各个部,那如果要拿指定的部分出来的话也很容易,如
echo parse_url($url, PHP_URL_PATH);
就是在第二个参数中,设定如下的参数:
PHP_URL_SCHEME, PHP_URL_HOST, PHP_URL_PORT, PHP_URL_USER, PHP_URL_PASS, PHP_URL_PATH, PHP_URL_QUERY or PHP_URL_FRAGMENT.
