php - Search and replace multiple values with multiple/different values in PHP5?

Question

Is there an inbuilt PHP function to replace multiple values inside a string with an array that dictates exactly what is replaced with what?

For example:

$searchreplace_array = Array('blah' => 'bleh', 'blarh' => 'blerh');
$string = 'blah blarh bleh bleh blarh';

And the resulting would be: 'bleh blerh bleh bleh blerh'.

Answer 1

You are looking for str_replace().

$string = 'blah blarh bleh bleh blarh';
$result = str_replace(
  array('blah', 'blarh'), 
  array('bleh', 'blerh'), 
  $string
);

// Additional tip:

And if you are stuck with an associative array like in your example, you can split it up like that:

$searchReplaceArray = array(
  'blah' => 'bleh', 
  'blarh' => 'blerh'
);
$result = str_replace(
  array_keys($searchReplaceArray), 
  array_values($searchReplaceArray), 
  $string
);
