What about performance ? What about compexity ?
Those SO nice seperated template system produces lots of mini TPL files. You
have to include them... You have to parse them.
Also you have to track and manage them.
And I'm not sure those template system gives you freedom. Because you cannot
change your site design with this tpl files. If you change them too much you
have to change your php code.
Plus if I remember correctly there was thing named CSS to change your site
looks.
After 10 years of html coding by hand and 6 years of php coding and from my
uber biased point of view. That template engine thing was flawed.
Look open source cms projects, check open sourced forums etc etc. Then tell me
what is effective use of tpl files for message posting form or blog showing
pages. Or someting like that...
Oh yes I know lots of sites are using them, then what ? People still use
windows... Is that makes Windows best operating system ?
Maybe it useful. when your Designer does not know php and or your programmer
does not know html/css.
And my point of view. Using <html tag <?php echo value ?> > <?php echo
value ?></htmltag> days are over...
These days we have to deal lots of other programming things. handle heavy
loads, do lots of security things etc etc...
Of course you could do nice things for your liddle home page via old style
php.
I believe Satyam's idea was best. I try to implement his idea with my way
function getTab($intTab=1)
{
$strTab = NULL;
for($i=0;$i<$intTab;$i++)
{
$strTab.= "\t";
}
return $strTab;
}
function html($arrOpt)
{
$arrKeys = array_keys($arrOpt['attlist']);
$intSize = sizeof($arrOpt['attlist']);
$strAttlist = null;
for($a=0;$a<$intSize;$a++)
{
$strAttlist.= " ".$arrKeys[$a]."='".$arrOpt['attlist'][$arrKeys[$a]]."'";
}
return getTab($arrOpt['tab'])."<".$arrOpt['tag'].@$strAttlist.
$arrOpt['end'].">\n";
}
MY RECENT METHOD
$strReturn.=
html(array('tag'=>'table','attlist'=>array('id'=>'uberTable','border'=>'0','cellpadding'=>'0','cellspacing'=>'1','width'=>'100%','class'=>'cUberTable'),'tab'=>4,'end'=>NULL))
.html(array('tag'=>'tr','attlist'=>array('class'=>'cUberTableTR'),'tab'=>5,'end'=>NULL))
.html(array('tag'=>'td','attlist'=>array('align'=>'center','valign'=>'top','class'=>'cUberTableTD'),'tab'=>6,'end'=>NULL))
."Test Message\n"
.html(array('tag'=>'/td','tab'=>6,'end'=>NULL))
.html(array('tag'=>'/tr','tab'=>5,'end'=>NULL))
.html(array('tag'=>'/table','tab'=>4,'end'=>NULL));
TPL METHOD
uber.tpl
<table id='uberTable' border='0' cellpadding='0' cellspacing='1'
width='100%' class='cUberTable'>
<tr class='cUberTableTR'>
<td align='center' valign='top' class='cUberTableTD'>
|MESSAGE|
</td>
</tr>
</table>
Code
$TPL = new TplClass;
$TPL-> SetTplPath('tpl/meta.tpl',__FILE__,__LINE__);
$TPL-> ReadTpl();
$TPL -> Assign('|MESSAGE| ,'Test Message',__FILE__, __LINE__);
$TPL -> Showtpl();
SATYAM WAY
<table &border '0' &colspan '0' &cellpadding '1' &width '100%'
class 'uberTable';
{
<tr
{
<td &align 'right' &valign 'top';
{
? "Test message ";
}
}
}
(and his curret implementation need pre-compiler)
Those Codes produces html like this
<table id='uberTable' border='0' cellpadding='0' cellspacing='1'
width='100%' class='cUberTable'>
<tr class='cUberTableTR'>
<td align='center' valign='top' class='cUberTableTD'>
Test Message
</td>
</tr>
</table>
I wish to access his works under php via pear or someting like that. And I
believe later or sooner we see this kind of aproach in other languages.
I hope php was first one.
Hope Larsmus see this...

Sancar
