用多个Variable替换多个String

Question

I Want change all Strings starting with {" and ending with "} to a variable, for example:

Hello {username}, -> to Hello $array['username']
Your Country is {country}, -> Your Country is $array['country']

But i get all strings text from database with one variable (Mysql) With $array['content']

What I Want:

str_replace("{$whatinhere}",$array['$copytohere'],$array['content']);

str_replace("{company}",$array['company'],$array['content']);

Answer 1

Use preg_replace_callback function

echo preg_replace_callback('~{(.+?)}~', 
        function($x) use ($array) { return isset($array[$x[1]]) ? $array[$x[1]] : ''; }, 
        $array['content']);
