A Strict() Master - PHP

Typically, most PHP-based Web sites use scripts which containintermingled PHP and HTML code. While this speeds up development, it alsohas a downside: an interface designer cannot modify page layouts or HTMLtemplates without the assistance of an experienced PHP developer. Well,there's a solution to the problem - and you'll be surprised to hear thatit's been around for quite a while. Say hello to PHP FastTemplate.

TOOLS YOU CAN USE

While the methods discussed above will suffice for most of your FastTemplate requirements, the class also comes with a bunch of ancillary capabilities.

The strict() method is used to display an error if FastTemplate finds template variables without any values assigned to them; these undefined variables will also appear as is in the final output.

<? // strict error checking $obj->strict(); ?>
The opposite of this is the no_strict() method, which replaces these unassigned variables with empty strings.

<? // turn off error checking $obj->no_strict(); ?>
The fetch() method returns the raw data which results from a parse() operation. Consider the following:

<? // parse templates $obj->parse(RESULT, "list"); // print echo $obj->fetch("RESULT"); ?>
The clear() method is used to clear variables.

<? // parse templates$obj->parse(RESULT, "list");// clear$obj->clear("RESULT");// prints nothing$obj->FastPrint("RESULT");?>
The get_assigned() method is used to obtain the value of any FastTemplate variable.

<? $obj->assign("EMAIL", "jdoe@somewhere.com"); // returns "jdoe@somewhere.com" echo $obj->get_assigned("EMAIL"); ?>
And finally, the utime() function comes in handy when you need to measure script execution time.

<? // list.php - item list // include class file include("class.FastTemplate.php3"); // instantiate new object $obj = new FastTemplate("./tmpl/"); // get start time $begin = $obj->utime(); // assign names for template files $obj->define(array( "list" => "list.tpl", "list_item" => "list_item.tpl" )); // get item list // assume it looks like this.. $items = array("vanilla", "pineapple", "strawberry", "chocolate chip", "peach", "banana", "grape"); // build LISTCONTENT variable by concatenation of multiple instances of "list_item" template for ($x=0; $x<sizeof($items); $x++) { $obj->assign("ITEM", $items[$x]); $obj->parse(LISTCONTENT, ".list_item"); } // parse templates $obj->parse(RESULT, "list"); // and print $obj->FastPrint(RESULT); // get end time $end = $obj->utime(); // print script execution time echo "Done in " . sprintf("%01.3f ", ($end - $begin)) ." seconds."; ?>
