Parse an imported string e.g. from a database for php variable names and replace them with their
values.
example:
In the String "Dear $firstname $lastname, welcome to our Homepage" the variables shall be
replaced with the respective values.
<?php
$welcome = getImportedString();
$firstname = "David";
$lastname = "Forger";
echo $welcome;
// before replacement output will be:
//"Dear $firstname $lastname, welcome to our Homepage"
function replaceVars($match) {
return $GLOBALS[$match[1]];
}
$welcome = preg_replace_callback('/\$(\w+)/i', "replaceVars", $welcome);
echo $welcome;
//now output will be:
//"Dear David Forger, welcome to our Homepage"
?>
