html - PHP expression <<<EOB -

-

I have been developing with PHP for some years, and recently came into this code:

I have never seen this approach to print HTML, which seems to be very useful and less than a few strange variables or low expressions syntax error.

We have discovered some official information about this and only got a position of Rasmus talking about this.

What is the detailed explanation about this functionality and what does EOB mean? Maybe the end of the block ?

It is known as syntax. The document will tell you everything that is told.

Originally, though:

A third way to limit the string is the headoc (syntax) syntax: & lt; & Lt; & Lt;. After this operator, an identifier is provided, then a new line string is in its own way, and then the same identifier again to stop the quote.

The closing identifier should start in the first column of the line. Additionally, the identifier must follow the same naming rules as any other label in PHP: It should only contain alphanumeric characters and underscores, and should start with a non-digit letter or underscore.

Then the author selects it as its delimiter, in fact it is not sure what it means in its case, but the identifier is that too Which you want. / P>

There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
