Question

拿这个域：

http://www.?.co.uk/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html

我如何使用PHP查找第一个和第二个斜杠之间的所有内容，无论它是否发生变化？

IE中。老年护理倡导

任何人都会非常感激。

Answer 1

//strip the "http://" part. Note: Doesn't work for HTTPS!
$url = substr("http://www.example.com/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html", 7);

// split the URL in parts
$parts = explode("/", $url);

// The second part (offset 1) is the part we look for
if (count($parts) > 1) {
    $segment = $parts[1];
} else {
    throw new Exception("Full URLs please!");
}

Answer 2

$url = "http://www.example.co.uk/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html";
$parts = parse_url($url);
$host = $parts['host'];
$path = $parts['path'];

$items = preg_split('/\//',$path,null,PREG_SPLIT_NO_EMPTY);

$firstPart = $items[0];

Answer 3

脱离我的头顶：

$url = http://www.example.co.uk/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html
$urlParts = parse_url($url); // An array
$target_string = $urlParts[1] // 'elderly-care-advocacy'

干杯

Answer 4

explode('/', $a);

Answer 5

所有你应该做的，首先解析网址，然后爆炸字符串并获得第一部分。通过一些健全性检查会像下面这样：

$url = 'http://www.?.co.uk/elderly-care-advocacy/mental-capacity-act-advance-medical-directive.html';
$url_parts = parse_url($url);
if (isset($url_parts['path'])) {
    $path_components = explode('/', $ul_parts['path']);
    if (count($path_components) > 1) {
        // All is OK. Path's first component is in $path_components[0]
    } else {
        // Throw an error, since there is no directory specified in path
        // Or you could assume, that $path_components[0] is the actual path
    }
} else {
    // Throw an error, since there is no path component was found
}

Answer 6

我认为Regular Expression应该没问题。

尝试使用例如：/[^/]+/，它应该为您提供/elderly-care-advocacy/作为示例中数组的第二个索引。

（第一个字符串是/ www。？。com /）

Answer 7

Parse_URL是您的最佳选择。它将URL字符串分解为组件，您可以选择性地查询它们。

可以使用此功能：

function extract_domain($url){

    if ($url_parts = parse_url($url), $prefix = 'www.', $suffix = '.co.uk') {
        $host = $url_parts['host'];
        $host = str_replace($prefix,'',$host);
        $host = str_replace($suffix,'',$host);
        return $host;
    }
    return false;
}

$host_component = extract_domain($_SERVER['REQUEST_URI']);

Answer 8

我也很惊讶，但这很有效。

$url='http://www.?.co.uk/elderly-care-advocacy/...'
$result=explode('/',$url)[3];

使用PHP查找URL的一部分
