您可以使用parse_url
功能,它会将URL分解为其组件,以便更轻松地单独匹配每个组件:
var_dump(parse_url("https://vine.co/v/"));
// array(3) {
// ["scheme"]=>
// string(4) "http"
// ["host"]=>
// string(7) "vine.co"
// ["path"]=>
// string(3) "/v/"
// }
然后,您只需检查scheme
,host
和path
是否匹配:
function checkVineURL($url) {
$urlpart = parse_url($url);
if($urlpart["scheme"] === "http" || $urlpart["scheme"] === "https") {
if($urlpart["host"] === "vine.co" || $urlpart["host"] === "www.vine.co") {
if(strpos($urlpart["path"], "/v/") === 0) {
return true;
}
}
}
return false;
}
checkVineURL("https://vine.co/v/"); // true
checkVineURL("http://vine.co/v/"); // true
checkVineURL("https://www.vine.co/v/"); // true
checkVineURL("http://www.vine.co/v/"); // true
checkVineURL("ftp://vine.co/v/"); // false
checkVineURL("http://vine1.co/v/"); // false
checkVineURL("http://vine.co/v1/"); // false

只需取出" https://"并稍微改变你的if
陈述......就像这样:
$vineURL = 'vine.co/v/';
if(stripos($user_input_value, $vineURL) !== false) {
echo "This is a vine URL";
} else {
echo "This is not a vine URL";
}

像这样的用户RegEx
if (preg_match("/^http(s)?:\/\/(www\.)?vine\.co\/v\//", $url)) {
echo "This is a vine URL";
} else {
echo "This is not a vine URL";
}
