problems with preg_replace

[Norsk.Firefox]

Hello, I use this preg_replace:

 

preg_replace('/\{(.*?).*?)\}/e',  'replace(${1}, ${2})', $var);

 

witch calls this function:

 

function replace($array, $var)
{
switch($array)
{
	case 'GET':
		return $_GET[$var];
	case 'POST':
		return $_POST[$var];
	case 'DATA':
		return data[$var];
}

return '';
}

 

This part works fine with {DATA:abc}, {GET:page} etc. But I do also want to the possible to choose between elements, so when i trie to add another case to the switch and use {TIF:DATA,abc,0=zero,1=one} it won't work any more. I get this error:

 

Parse error: syntax error, unexpected '=' in C:\page.php(101) : regexp code on line 1

 

Fatal error: preg_replace() [<a href='function.preg-replace'>function.preg-replace</a>]: Failed evaluating code: replace(TIF:DATA,abc,0=zero,1=one) in C:\page.php on line 101

 

Anyone have a solution to this problem?
