Question

i need function in PHP for handle replacement something like this.

$pattern = ':foo/anotherString';

$replacement = array(
    'foo' => 'HelloMe'
);

bazFunction($pattern, $replacement); // return 'HelloMe/anotherString';

this method used in some frameworks as route patterns. i want to know which function handle that.

Answer 1

this should do (5.3 required because of the closure)

function my_replace($pattern, $replacement) {
  // add ':' prefix to every key
  $keys = array_map(function($element) {
    return ':' . $element;
  }, array_keys($replacement));

  return str_replace($keys, array_values($replacement), $pattern);
}

You wouldn’t need this function if you pass the stuff directly to str_replace

str_replace(array(':foo'), array('HelloMe'), ':foo/anotherString');
