how to replace these variable?

lnfreish

hello, everyone:
I have met a problem, when I read some template files, I need replace some variable in it.
e.g.
-----test.tpl-----
<html>
<head><title>$myvar[1001]</title></head>
<body>
$myvar[1002]
$myvar[2042]
$myvar[3004]
</body>
</html>

you know, all the variables in the template is an array. but not every template file have so many variables, maybe none, maybe several, maybe dozens, so I need replace these variable. I use a function such as:

function loadTemplateFile($file = "") {
    global $myvar;

$fp = fopen($file,"r");
$output = fread($fp,filesize($file));
fclose($fp);

//I need replace the variable here, maybe need eregi_replace or preg_replace, but I am not familiar with them.

return $output;
}

expect you can help me, thank you!

What kind of vars do you need to replace?? INT, String Bol??

well let me give you a example of what you can do:


foreach($array_var as $key => $value)
{
     //test your array for values you need to change here
     if($value == "Your Value")
     {       

           $array_var[$key] = $new_value
     }

//any thing else that you want to do to each element in the array
}

How about doing this?

-----test.tpl----- 
<html> 
<head><title><?php echo $myvar[1001]; ?></title></head> 
<body> 
<?php echo $myvar[1002]; ?>
<?php echo $myvar[2042]; ?>
<?php echo $myvar[3004]; ?>
</body> 
</html>

If that's not complex enough, how about this function:

//-----------------------------------------------------------------------------
// string template_parse($template, $variables)
//-----------------------------------------------------------------------------
// Parses a template string using the variables extracted from an associative
// array. The template should only contain simple 'echo' and/or 'if'
// statements. Template execution starts in HTML mode.
//-----------------------------------------------------------------------------
// PARAMETERS:
// $template - a string with embedded php statements.
// $variables - an associate array of variables.
//-----------------------------------------------------------------------------
// RETURNS:
// string - results of executing the template.
//-----------------------------------------------------------------------------
function template_parse($template, $variables){
	extract($variables);
	ob_start();
	eval("?>" . $template . "<?php ");
	$output = ob_get_contents();
	ob_end_clean();
	return $output;
}

Templates should be simple with php. You could simply include 'test.tpl' after loading the arrays too. You really don't need to make it complex just because php makes it simple.

thank you, I will try it!

thank you, maybe you have not understood my means(my english is so poor), I know Include or rRequire can solve this problem, but now I will supply this template to others who maybe have no any knowledge in PHP, so I decide to use template tech to solve this problem. because they maybe need modify the template to fit their interest.

I think if you keep the PHP tags simple and short you could explain it to the others. If they can figure out HTML then they should be able to learn to keep their mits off your PHP tags. If they can't learn to keep their mits off your PHP tags what hope do you have for these $myvar[1002].

And consider the added benefit of some simple statements like these in your template:

<html>
<head>
<title>
<!-- DON'T TOUCH MY PHP TAGS OR YOUR FIRED -->
<?php echo $site_title; ?>
<?php if($page_title){ echo " - "; } ?>
<?php echo $page_title;  ?>
<!-- IF YOU EVEN THOUGHT ABOUT TOUCHING THEM START PACKING -->
</title>

Your page just became much more Google freindly! Can't do that with just variables.

I realise your trying to make it simple for your page designers, but it's not making it easier for you. You'll end up designing an entire templating system. But, PHP is a templating system and has always been a templating system. It's just hard to see that with all the hundreds of extensions.

I'll stop preeching now and crawl back under my rock. My third post and I'm ranting. I'm hopeless.

Good luck on your project.
