get meta tags with php don't work -


मुझे एक मेटा लेना चाहिये 

  & lt; meta name = "twitter: खिलाड़ी "वर्ग =" ट्विटर_प्लेयर "मान =" https://www.slideshare.net/slideshow/embed_code/31306908 "& gt; पीएचपी में, get_meta_tags (url) के साथ सभी मेटा टैग लेते हैं लेकिन इस तरह के मेटा का मान शून्य है, मैं इस मेटा से कोशिश करना चाहता हूं और  
  $ doc = नया DOMDocument; $ डॉक्टर & gt; loadHTMLFile ($ मूल्यों [ 'ig_create_url']); $ मेटा = $ doc- & gt; getElementsByTagName ('मेटा');  
 
 हालांकि यह काम नहीं कर रहा है, 0 ऑब्जेक्ट के साथ ऑब्जेक्ट वापस आओ

< P> आप इसका मतलब है?

<पूर्व> $ doc = new DOMDocument; $ Doc- & gt; लोड एचटीएमएल ('& lt; मेटा नाम =' ट्विटर: खिलाड़ी "वर्ग =" ट्विटर_प्लेयर "मान =" https://www.slideshare.net/slideshow/embed_code/31306908 "& gt; '); विदेशी मुद्रा ($ doc- & gt; getElementsByTagName ('मेटा') $ टैग के रूप में) {गूंज $ टैग- & gt; getAttribute ('मान'); }

आउटपुट: 

  https://www.slideshare.net/slideshow/ Embed_code / 31306908

संपादित करें:

ऐसा ही है लेकिन, मुझे लोड चाहिए उस सभी मेटा टैग से प्राप्त करने के लिए एक लिंक

आपको इसके लिए file_get_contents () का उपयोग करने की आवश्यकता है। 

  $ Html = file_get_contents ('http://yoururl.com'); $ Doc = नया DOMDocument; $ डॉक्टर & gt; @loadHTML ($ एचटीएमएल); // & lt; ----- ऊपर दिए गए $ html वेरिएबल पास करें

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
