First, when the break is called,There is no need to execute the iteration after the break is called in the loop.Because parallel execution breaks down the execution order, it is very likely that some iterations that do not need to be executed have
When you throw an exception in a task execution, for example:
Task. Factory. startnew () =>

different programs directly referenced, without repeatedly installing too many copies of the Smarty. And the author provides the way is suitable to bring the program to move over the program developers use, so do not worry about the host has not installed Smarty.
Program Folder Settings
Take the author in the Windows installation Appserv as an example, the program's main folder is "d:\appserv\web\demo\". After installing the smarty, we will create the folder under the main folder

First, explain the difference between using a template and using the echo or print command to create an html page. echo and print are very useful in writing short scripts, however, the organization and customization of the scripts made are not good, and it takes a lot of effort to modify them. templates are much more efficient in writing websites that support multiple languages, for example, echo and p

outputting a page through echo or PRint.The echo/print method is suitable for writing short scripts, but it cannot help you better organize and customize the scripts. In additionBy modifying a parameter. They can make you more concerned about what you want to do.
Do not be afraid to think before coding. It may take some time, but it will return to you as the project develops.
So, how to apply FastTemplate? First, you need to make a simple call:

the author in the Windows installation Appserv as an example, the program's main folder is "d:\appserv\web\demo\". After installing the smarty, we will create the folder under the main folder:Under Linux, remember to change the permissions of the Templates_c to 777. It is read-only cancellation under Windows.

simple call:
Pass it a path, which is the directory where all your template files are stored. It returns an object. You can use it for parameters.Number Assignment, page generation, and so on.
Fasttemplate is based on the assumption that a large page is composed of many small parts. Each part has a unique. The smallest part is a normal text string with a unique name. You can use$ TPL-> assign (name, "text ");?>. Now, if one of your templates co

Let me explain the difference between generating a page using a template and simply outputting a page through echo or PRint.The echo/print method is suitable for writing short scripts, but it cannot help you better organize and customize the scripts. In additionBy modifying a parameter. They can make you more concerned about what you want to do.

needs. the advantage of doing so is that you can easily maintain the site, and if this public part needs to be changed, you do not need to modify every page, greatly reducing our workload.In the past, you may use require, include (require_once, include_once) to introduce a public page header, which is indeed convenient and effective. Now we can use the template class to implement it, you can easily insert a page to any part of another template. if you want to make the page to be inserted into a
As you can see, the examples in the previous sections use$ TPL-> set_file ("Main", "template file name ");To load the template file. The name is only "Main" because we want to give it a meaning: The main template. "Sub-template". Similarly, footer.html is also a "sub-template". We want to place it in the {footer} position of the main template. A master template can be embedded with any number of sub-templates with unlimited content, size, and format.
php file, the latter is like the header and tail of the page that a site needs. the advantage of doing so is that you can easily maintain the site, and if this public part needs to be changed, you do not need to modify every page, greatly reducing our workload.In the past, you may use require, include (require_once, include_once) to introduce a public page header, which is indeed convenient and effective. now we can use the Template class to implement it, you can easily insert a page to any par
