[SOLVED] Question about Regular Expressions

[All4172]

What I'm wanting to do is a statement like:

 

$file = "/path/www/mydir/3429438.php";

if ($file == "/path/www/mydir/"){
$file = "/path/www/NEWmydir/3429438.php;}

 

Quesiton is what regular expression in the if statement so it'll search /[0-9].php and how to take that filename and apend it on the new $file if the instance exists.  Ideas?

Try this:

 

if (preg_match('|/([0-9]+)\.php$|', $file, &$matches) === 1) {
  print "Matched {$matches[1]}\n";
}

 

Then you can use $matches[1] to construct your new path (if all you want to do is replace mydir with NEWmydir)
