Hi there, Please help me out in the following... <?php $is='is'; echo eregi_replace(" ".$is." "," ","This is a test string which contains is in dismissal"); ?> Actually I want to replace "is" alone from the string and not all the words that contains is... I have tried with "^".$is."$" ---> but yields nothing.... thanks and regards, Desikan On Fri, 8 Feb 2002 08:52:10 -0600 , "Rick Emery" <remery@excel.com> said: > To get "is" alone, use " is " > > -----Original Message----- > From: Desikan [mailto:desikb4u@fastmail.fm] > Sent: Friday, February 08, 2002 8:51 AM > To: Rick Emery > Subject: RE: [PHP-DB] Exact String replace with eregi_replace() > > > hi there, > > Actually ^string$ represents the exact match of the string alone, and not > words containg that sring... > > thanks > Desikan > > On Fri, 8 Feb 2002 08:46:32 -0600 , "Rick Emery" <remery@excel.com> said: > > First, the example you give will replace "is" with "," if > > "is" is the > > ONLY > > work in the line.
