HTML_Template_IT in PEAR is a simple and easy-to-use class. ********** Create a template file**************** The "symbol" naming rule is the following regular expression: {[0-9A-Za- z_-]+} "Block" format is as follows, the naming rules of block names are the same as "symbol": ...Block content... Blocks allow nesting, you must first set and analyze The innermost block, and then the blocks on the upper level are set and analyzed. *********** Main method************ Constructor: void IntegratedTemplate::IntegratedTemplate ([string $root = ""]) $root = template root directory You can also use the void IntegratedTemplate::setRoot (string $root) method to set the template directory; this method cannot be called statically. -------------------------------------------------- ------- Load template: boolean IntegratedTemplate::loadTemplatefile (string $filename, boolean [$removeUnknownVariables = TRUE], boolean [$removeEmptyBlocks = TRUE]) $filename = template file name $removeUnknownVariables = Set whether to remove unknown The variable $removeEmptyBlocks = sets whether to remove empty blocks and returns TRUE if successful, and FALSE if failed. This method cannot be called statically---------------------------------------------- ----------- Specify the current block to be processed: boolean IntegratedTemplate::setCurrentBlock ([string $block = "__global"]) $block = block name Returns TRUE if successful, or a PEAR_Error object if failed. It contains a description of the error. This method cannot be called statically. -------------------------------------------------- ----- Use a variable to replace the "symbol" in the block currently being processed: void IntegratedTemplate::setVariable (mixed $placeholder [, mixed $variable = ""]) $placeholder = the name of the symbol to be replaced, if $variable is an array, then use the symbol name as the index of the array and replace the symbol with the data of the array element at this index $variable = variable name or array name This function cannot be called statically------------ ----------------------------------------------- Analyze the block currently being processed : void IntegratedTemplate::parseCurrentBlock () will return a PEAR_Error object if it fails, which contains the error description. This method cannot be called statically. -------------------------------------------------- ------- Processing completion output: void IntegratedTemplate::show ([string $block]) $block = the block to be returned. If $block is not set, the complete template will be returned ********* ********** Simple example (the example comes from PEAR's online manual)***** Usage Example Example 25-1. main.tpl.htm template file, in the "./templates" directory {DATA} Example 25-2. PHP script array("Stig", "Bakken"), "1" => array("Martin" , "Jansen"), "2" => array("Alexander", "Merz") ); $tpl = new HTML_Template_IT("./templates"); $tpl->loadTemplatefile("main.tpl.htm", true, true); foreach($data as $name) { foreach($name as $cell) { // Assign data to the inner block $tpl->setCurrentBlock("cell") ; $tpl->setVariable("DATA ", $cell) ; $tpl->parseCurrentBlock("cell") ; } // Assign data and the inner block to the // outer block $tpl->setCurrentBlock("row") ; $tpl->parseCurrentBlock(" row") ; } // Output $tpl->show(); ?> Example 25-3. Output Stig Bakken Martin Jansen Alexander Merz ************** ***************************************** There is also an ITX class in HTML_Template_IT, which can To complete more complex functions, inherit from IT class; ITX. The original code of the PHP file contains the method description of this class. For detailed instructions on other methods of HTML_Template_IT, please refer to the PEAR manual at http://pear.php.net/manual/en/package.html.html-template-it.php -- I hope everyone can make good use of the PEAR library Write more and better PHP programs! --
