Drupal code implements URL rewrite _php tips

Here is the implementation example:

Copy Code code as follows:

/*
* Pseudo address to the original address (Url_alter)
*/
Function Example_url_inbound_alter (& $path, $original _path, $path _language)
{
if (Preg_match |^article (/.*) |, $path, $matches)) {
$path = ' node '. $matches [1];
}
}
/*
* Original address to the pseudo address (Url_alter)
*/
Function Example_url_outbound_alter (& $path, & $options, $original _path)
{
if (Preg_match |^node (/.*) |, $path, $matches)) {
$path = ' article '. $matches [1];
}
}

PS: When implementing Hook_url_inbound_alter, I do not know why the implementation function could not be adjusted, possibly because the hook was loaded prematurely and did not load the module completely. So my approach is to write in the URL rewrite module, such as Subpath_alias
