The Html_template_it in pear is a simple and easy-to-use class.


Create a template file ****************
The "symbol" naming convention is the following regular expression:
{[0-9a-za-z_-]+}
The "block" format is the following, with the block name naming convention and the same as "symbol":

... Block content ...

Blocks allow nesting, you must first set up and analyze the inner blocks, and then set and analyze the blocks on the previous layer.





Main methods ***********
constructor function:
void Integratedtemplate::integratedtemplate ([String $root = ""])
$root = Touch Plate root directory
You can also use
void Integratedtemplate::setroot (String $root)
method to set the template directory; The method cannot be called statically.
---------------------------------------------------------
To load a template:
Boolean Integratedtemplate::loadtemplatefile (String $filename, Boolean [$removeUnknownVariables = TRUE], Boolean [$ Removeemptyblocks = TRUE])
$filename = Template file name
$removeUnknownVariables = Sets whether the unknown variable is removed
$removeEmptyBlocks = set whether to remove empty blocks
The success returns True, and the failure returns false.

-------------------------------------------------------
Specify the block currently being processed:
Boolean Integratedtemplate::setcurrentblock ([String $block = "__global"])
$block = block Name

Describe. The method cannot be called statically.
-------------------------------------------------------
Replace the "symbol" in the block currently being processed with a variable:
void integratedtemplate::setvariable (mixed $placeholder [, Mixed $variable = ""])
$placeholder = The symbol name to replace, if $variable is an array,
Then use the symbol name as the index of this array and use the cable
Data substitution symbol for an array element that is cited
$variable = variable name or array name
The function cannot be called statically
--------------------------------------------------------
Parse the block currently being processed:
void Integratedtemplate::p arsecurrentblock ()
Failure will return a Pear_error object containing an error
