/*
about template()
$arr is a set of values where the key(uppercase) is what is looked for and the
value is the value to be replaced globally in the template.
i.e.: $arr['BODY'] = "...";
will replace the value {BODY} in the template.
$scheme is more for themes and are pretty easy to figure out.
$text is a textual value to use instead of loading a file.
$returns if set to 0 will cause the function to just echo the parsed template instead
of returning it as a string.
$base_override is to change the template base on the fly, this is useful for global templates.
call like template($replacements, "", 1, "", "/directory/to/global/templates/_mainheader")
setting $arr['template'] = "file.tpl" will cause the function to load sub-template file.
this is generally for loading simple rows and tables that may be repeated to be tossed into the
main template fuction.
Was using eregi for replacements, but then ran some test over a 1000 iterations for a file
and:
speed in 3.12413215637 seconds for eregi
speed in 1.04641199112 seconds for str_replace
so obviously str_replace is the choice.
this works like so:
you check http://site.com/reports/report.php
csr main file says BASE_TEMPLATE_PATH = /var/www/site/templates/main
script_name returns /reports/report.php
the base becomes /var/www/site/templates/main/reports/report.php/
for all templates relating to that page.
