HTML is sometimes quite troublesome, especially when we want to apply XTHML. We can use the usual method to include form elements in the Symfony template, as shown below, but Symfony provides a helper to make this task easier.

This article describes the PHP implementation of blog, forum pictures anti-theft chain method. Share to everyone for your reference, specific as follows:
Anti-Theft chain of a lot of ways, I would like to say that I have to put hotlinking understanding, this with the prevention of remote submission is a principle.
Let's introduce a function
Uniqid (string);
The function is to add a unique ID string immediately after the string you add.
If you're not sure, you can use the SHA1 ()
Example of regular expressions
The following table shows examples of the use of regular expressions. All of the examples apply to REGEXP, and some of the examples apply to the SIMILAR to, such as comments in the sample column. The results vary depending on the search criteria that you use for the search. For examples that use SIMILAR to, the results also vary depending on whether the case is case-sensitive or accented.
For a comparison of how REGEXP and SIMILAR to handle matching and calculation
