php - Checking 1000 urls if they exist or not, is there a quick way for this? -

-

I have an array of URLs (~ 1000 URLs in it), I want to see them all if they exist or No . Here's my current code: 

  $ south_east_png_endings = array (); ($ Y = 1; $ y & lt; = 48; $ y ++) {$ south_east_png_endings [] = "$ {$ x = 1; $ x   
 This script works, it removes all the action URLs, but this process is very long (it takes several minutes to complete). Is there a way to speed it up or is it as fast as it is happening? Maybe I can use the curl_timeout functions to reduce the time?   
 
 
 1) get_headers () actually receives the request, which is not necessary if you want to know Use a head instead of whether a file exists or not:  
  & lt ;? Php // uses a GET request to get the get_headers header by default if you want to send // a HEAD request instead, you can do this by using a stream reference: stream_context_set_default (' Http '= & gt; array (' method '= & gt;' HEAD '))); $ Header = get_headers ('http://example.com'); ? & Gt;   
 2) Since these checks can easily run in parallel, you should use different threads / processes to check. However, if you are doing it from home, then your router can suppress 1000 requests once, so you would like to use something like 5-20 concurrent threads.

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
