How to strip domain name out of a url in PHP? - 


  parse_url ($ url, PHP_URL_HOST)

उपर्युक्त के लिए काम करेगा :

sub1.domain.name ,

sub2.domain.name , ...

मैं केवल डोमेन नाम पट्टी करना चाहता हूं।

इसलिए जो आप से शुरू कर रहे हैं वह यूआरएल नहीं है।

सबसे आसान तरीका यह है कि यह यूआरएल की तरह दिखता है: 

  function get_host_from_bad_url ($ url) {if (! $ Candidate_host = parse_url ($ url, PHP_URL_HOST)) {// जानबूझकर असाइनमेंट $ candidate_host = parse_url ('http: //'। $ Url, PHP_URL_HOST); } वापसी $ condidate_host; }

सभी प्रकार की अन्य चीजें हैं जो हो सकता है में मेजबान नाम होता है - लेकिन बहुत अधिक जानकारी के बिना इसकी व्याख्या करना कठिन है।

हालांकि एक वैकल्पिक दृष्टिकोण कुछ भी निकालने का प्रयास करने के लिए होगा, जैसा दिखता है कि यह एक होस्टनाम हो सकता है (और उसके बाद संभावित रूप से, DNS जांच कर सकते हैं): 

  function strip_hosts_from_string $ Inp) {$ inp = strtolower ($ inp); $ से मेल खाता है = preg_match_all ( '/ ([एक-Z0-9 \ -] \) {2,} ([a-z] {2,6}) /।', $ Inp); $ होस्ट नामों = $ मैचों [0]; विदेशी मुद्रा ($ मेजबाननाम $ x = & gt; $ होस्ट) {if (gethostbyname ($ host) == $ मेजबान) {सेट ($ मेजबाननाम [$ x]); }} $ मेजबाननाम लौटें; }

सी।

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
