How to replace all matches with Regex / PHP / preg_replace

Question

basically I want to replace all words like : test , someword , bleble .

The problem is that regex I am using, only replaces one of the words, first one which is found . Can anyone help me with this one?

$string = 'http://nu/style/test/someword/bleble';
preg_replace('/(test|someword|bleble)/','',$string);

Best Regards, Mateusz

Answer 1

You can use an array to solve the problem.

$string  = "http://nu/style/test/someword/bleble";
$remove = array("/test/", "someword/", "bleble");

$result = str_replace($remove, ' ', $string);

Answer 2

You can use array() for your patterns. You need one array for the patterns, which may be replaced and another array for replacements.

$string = 'http://nu/style/test/someword/bleble';
$patterns = array(
  "/test/",
  "/someword/",
  "/bleble/"
);

$replacements = array(
  "",
  "",
  ""
);

preg_replace($patterns, $replacements, $string);

Of course, if you want to replace all the $patterns with the same word, you can use:

preg_replace($patterns, " ", $string);
