PHP String Replacement -

i wish have 1 string contains instance (mystring):

file config.php

$mystring = "hello name $name , got $school"; 

file index.php

include('config.php');  $name = $_get['name']; $school = $_get['school'];  echo $mystring; 

would work ? or there better ways

$string = 'hello, name %s , go %s'; printf($string, $_get['name'], $_get['school']); 

or

$string = 'hello, name :name , go :school'; echo str_replace(array(':name', ':school'), array($_get['name'], $_get['school']), $string); 

you can automate last 1 like:

function value_replace($values, $string) {     return str_replace(array_map(function ($v) { return ":$v"; }, array_keys($values)), $values, $string); }  $string = 'hello, name :name , go :school'; echo values_replace($_get, $string);
