PHP session not destroying or unsetting -

-

मेरे पास index.php में लॉगिन की जाँच के लिए यह निम्नलिखित PHP कोड है 

  & lt; ? Php session_start (); $ Con = mysqli_connect ("***", "***", "***", "***"); $ Fbid_check = $ _ सत्र [ 'loginid_session']; $ Fbphoto_session = $ _ सत्र [ 'loginphoto_session']; $ Fbname_sql = mysqli_query ($ con, "चुनें fb_name से uni_users WHERE fb_id = '$ fbid_check'"); $ Name_fetch = mysqli_fetch_array ($ fbname_sql, MYSQLI_ASSOC); $ Fbname_session = $ name_fetch [ 'fb_name']; If (isset ($ fbname_session)) {हैडर ("स्थान: http://www.uniwink.com/landing/profile.php"); } Mysqli_close ($ con); ? & Gt;

यह लॉगइन के लिए चेक करता है और प्रोफ़ाइल.फिप पर रीडायरेक्ट करता है जिसमें प्रवेश के लिए जाँच करने के लिए हैडर में निम्नलिखित PHP कोड होता है 

  & lt; php $ con = Mysqli_connect ("****", "****", "****", "****"); session_start (); $ Fbid_check = $ _ सत्र [ 'loginid_session']; $ Fbphoto_session = $ _ सत्र [ 'loginphoto_session']; $ Fbname_sql = mysqli_query ($ con, "चुनें fb_name से uni_users WHERE fb_id = '$ fbid_check'"); $ Name_fetch = mysqli_fetch_array ($ fbname_sql, MYSQLI_ASSOC); $ Fbname_session = $ name_fetch [ 'fb_name']; यदि (! Isset ($ fbname_session)) {हैडर ("स्थान: http://www.uniwink.com/landing"); } Mysqli_close ($ con); ? & Gt;

और मेरे पास यह निम्न logout.php है जिसे profile.php से कहा जाता है 

  & lt;? Php session_start (); सेट नहीं ($ _ सत्र [ 'loginid_session']); सेट नहीं ($ fbname_session); session_destroy (); हैडर ("स्थान: http://www.uniwink.com/landing"); बाहर जाएं(); ? & Gt;

समस्या लॉगआउट के बाद है, यह अभी भी profile.php में जाती है। ऐसा लगता है जैसे सत्र बिल्कुल भी नष्ट नहीं होता है। बात यह है कि वह कल तक ठीक से काम कर रही थी और अचानक सब कुछ हुआ था। धन्यवाद

सत्र की जांच करें। 

  यदि (isset ($ _SESSION ['loginid_session'])) {हेडर ("स्थान: http://www.uniwink.com/landing/profile.php"); } और {हेडर ("स्थान: http://www.uniwink.com/landing"); }

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
