迁移网站：eregi到preg_match？

Question

I'm in the process of migrating a horrible drupal site to a new server - a server with a newer version of PHP. Checking the site I get the following error:

Deprecated: Function ereg() is deprecated in /var/sites/n/nanohex.org/public_html/includes/file.inc on line 902

Line 902 looks like the following:

elseif ($depth >= $min_depth && ereg($mask, $file)) {

My understanding is that ereg is no longer used and I need to replace with pregmatch.

Changing the code the following...

 elseif ($depth >= $min_depth && preg_match('/\.([^\.]*$)/', $mask, $file)) {

throws up this error instead:

Warning: basename() expects parameter 1 to be string, array given in /var/sites/n/nanohex.org/public_html/includes/file.inc on line 905

Line 905 looks like this:

$basename = basename($file);

What am I doing wrong?

Answer 1

The matches are in the array $file. You have to use the second entry in this array:

$basename = basename($file[1]);

But I guess your preg_match should be:

preg_match('/\.([^\.]*$)/', $file)

and then:

$basename = basename($file);

is OK.
