str_replace in foreach not working

[israfel]

extract($styles);
foreach($styles as $stylename => $stylevalue) {
$template = str_replace("<$stylename>", "$stylevalue", "$templatebit");
}

With error_reporting set to maximum I have confirmed that $styles is a valid array and is being successfully extracted. In my script $styles is all the page colors and font variables that I want to replace in a template after grabbing it from the database before sending it to the browser so, in my templates I would simply write a variable as a html tag like <bgcolor> and the $styles array would have a key like $styles['bgcolor']. I want to replace any occurrances of <bgcolor> with the value of $styles['bgcolor'] along with any other variables found in the foreach loop but it just isn't working. When I test it by echoing template it just outputs the contents of the column making no replacements.

Can someone tell me what I'm doing wrong here?

your $template is simply reseting each time it goes through the loop.

use ".=" instead of just "=" sign. so its $template .= ...etc.

also you might aswell remove the " signs around the third param of str_replace as thats the string source.

Using the ".=" operator only made the script die... without solving my problem.

The point of this function is to take a template from the database, look for matches from an array of color and font replacement variables in the template, do the replacements and return the formatted string. If anyone knows of a better means of accomplishing this (without using something like Smarty) in a similar manner please let me know.

function getTemplate($template, $getcomments=1)
{
GLOBAL $c;
$result = mysql_query("SELECT templatetitle,templatevalue FROM arc_template WHERE templatename='$template' AND templatetype='default'");
$array = mysql_fetch_array($result);
extract($array, EXTR_OVERWRITE);
$colorstr = getColors($c);
include($colorstr);
extract($styles);
foreach($styles as $stylename => $stylevalue) {
$templatevalue = str_replace("<$stylename>", "$stylevalue", $templatevalue);
}
if ($getcomments==1) {
return "\n<!-- start $templatetitle -->\n$templatevalue\n<!-- end $templatetitle -->\n";
} else {
return $templatevalue;
}
}

And this is how I call the function...

$pquery = mysql_query("SELECT * FROM pagebit WHERE page='$action' ORDER BY pdate");
echo '<br />';
while ($page = mysql_fetch_assoc($pquery)) {
$pagebit = getTemplate('pagebit'); //get template 'pagebit'
extract($page, EXTR_OVERWRITE);
str_replace("<pagebit_title]>", "$ptitle", $pagebit);
str_replace("<pagebit_content]>", "$pcontent", $pagebit);
echo $pagebit;
}

I also echo'd the variables that are supposed to be inserted into the template to test them and they worked so the problematic code for me in both instances is str_replace. I tried using ereg_replace and preg_replace as well but neither helped.
