What is the context of this? Are you talking about replacing literal
"$LABEL{'label_name'}" with the value of _$SERVER['label_name'] in a string?
If so, you could try this where $s is the string that has the content
that will need the replacing:
<?php
$pattern='/\$LABEL\{\'([\w]+)\'\}/s';
if(preg_match_all($pattern,$s,$m)){
$matches=count($m[0]);
for($i=0;$i<$matches;$i++){
if(isset($_SERVER[$m[1][$i]])){
$s=str_replace($m[0][$i],$_SERVER[$m[1][$i]],$s);
}else{
$s=str_replace($m[0][$i],$m[1][$i],$s);
}
}
}
?>
