  फ़ंक्शन वैध टेक्स्ट ($ इनपुट, $ min = शून्य, $ max = null) {if (! (Empty ($ मिनट) और amp; खाली ($ अधिकतम)) {$ text = "^ [a-zA-z \ s0- 9] {$ min, $ max} + $"; } और {$ text = "/ ^ [a-zA-Z \ s0- 9] + $ /"; } यदि (preg_match ($ पाठ, $ इनपुट)) {वापस सत्य; } अन्य {वापसी झूठी; }}

समस्या क्या है? क्षमा करें नौसिखिया समस्या

समस्या पंक्ति में है: 

  $ पाठ = "^ [a-zA-Z \ s0- 9] {$ min, $ max} + $";

समस्या यह है कि {$ var} PHP में एक विशेष सिंटैक्स है $ var, $ var वैध वैरिएंबल नाम नहीं है, इसलिए {$ var, $ var} अमान्य है ...

इसे आज़माएं: < / P> 

  $ text = "^ [a-zA-z \ s0- 9] {{$ min}, {$ max}} + $";

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer?

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .
