$result = preg_replace(
"/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/iseU",
"CallFunction('\\1','\\2','\\3','\\4','\\5')",
$result
);
The above code gives a deprecation warning after upgrading to PHP 5.5:
Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead
How can I replace the code with preg_replace_callback()?

You can use an anonymous function to pass the matches to your function:
$result = preg_replace_callback(
"/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
$result
);
Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".
