Regular Expression - HeLP

[helpwanted]

Hi All,

I need regular Expression to match to the string "DirectoryName".Only this need to be validated .If it is specified as "Directory_Name" or "Directoryname",it must return error.Please help me giving regular expression for this in an PHP application

The regular expression "DirectoryName" will do that.  For example:

[code=php:0]if (ereg('DirectoryName', $string) == 1) {
  print "Match\n";
}[/code]


But it would be faster to use strpos:

[code=php:0]if (strpos($string, 'DirectoryName') !== false) {
  print "Match\n";
}[/code]
