thinkphp Single Letter function (shortcut method) Use Summary _php instance

In thinkphp, there are many easy to use single letter function (that is, shortcut method), can be very convenient for developers to call quickly, but the letter function is not convenient memory, this article will all the letter function summed up, to facilitate the search later.

1.U () URL assembly supports different URL patterns

U ($url = ', $vars = ', $suffix =true, $domain =false)

@param string $url URL expression, format: ' Module/controller/Action # anchor @ domain name]? parameter 1= value 1& parameter 2= value 2 ... '
@param string|array $vars incoming arguments, supports arrays and strings
@param string $suffix pseudo static suffix, the default is true to get configuration values
@param boolean $domain whether the domain name is displayed
@return string

2.D () D function to instantiate model class format [resource://][module/] Model

D ($name = ', $layer = ')

@param string $name Resource Address
@param string $layer model layer Name
@return Model

The 3.M () M function is used to instantiate a model without a modeling file

M ($name = ', $tablePrefix = ', $connection = ')

@param string $name model name supports specifying the underlying model such as Mongomodel:user
@param string $tablePrefix Table prefix
@param mixed $connection Database connection information
@return Model

4.I () get input parameter support filter and default value

I ($name, $default = ', $filter =null)

How to use:

 I (' id ', 0); Gets the ID parameter to automatically determine the GET or post
 I (' post.name ', ', ' htmlspecialchars ');//Get $_post[' name
 ' I (' getting. ');//Get $_get

5.B () Perform an action

 G (' begin '); Record start tag bit
 //... The interval runs code

 Statistical interval Memory Usage

If the end marker bit is not defined, it is automatically marked with the current as a bit
Where statistical memory usage requires the MEMORY_LIMIT_ON constant to be true to be valid
@param string $start start label
@param string $end end tag
@param integer|string $dec decimal places or M
@return Mixed

9.L () Get and set language definitions (case-insensitive)

L ($name =null, $value =null)
