can anyone please explain how ?

Answer 1

preg_replace('/www.example.com\\/(.+)\\/index.php/i', "www.example.com/index.php?lang=$1", $url); will do the thing

Answer 2

This is one way to do it:-

$newurl = preg_replace('/\/[a-z][a-z]\//', '/', $url);

Note that the search string appears with quotes and forward slashes ('/.../') and that the forward slashes in the URL then have to be escaped (\\/). The language code is then matched with '[az][az]', but there are several other ways to do this and you may want something more liberal in case there are ever 3 letter codes, or caps. Equally you may need to do something tighter depending on what other URL schemes might appear.

Answer 3

我怀疑在这种情况下，使用str_replace会更快，如下所示：

$cleanedData = str_replace(array('www.example.com/en/', 'www.example.com/fr/'), '', $sourceData);

Answer 4

Finally i got a method my thanks to Purpletoucan

$newurl = preg_replace('/\/(en|esp|fr)\//', '/', $url);

it's working now i think!
