问题
A column in the database I work with contains RTF strings, I would like to strip these out using PHP, leaving just the sentence between.
It is a MS SQL database 2005 if I recall correctly.
An example of the kind of strings pulled from the database (need any more let me know, all the rest are similar):
{\rtf1\ansi\ansicpg1252\deff0\deflang2057{\fonttbl{\f0\fnil\fcharset0 Tahoma;}}
\viewkind4\uc1\pard\lang1033\f0\fs17 ASSEMBLE COMPONENTS AS DETAILED ON DRAWING.\lang2057\fs17\par
}
I would like this to be stripped to only return:
ASSEMBLE COMPONENTS AS DETAILED ON DRAWING.
Now, I have successfully managed to strip the characters in ASP.NET for a previous project, however I would like to do so using PHP. Here is the regular expression I used in ASP.NET, which works flawlessly may I add:
"(\{.*\})|}|(\\\S+)"
However when I try to use the same expression in PHP with a preg_replace it does not strip half of the characters.
Any regex gurus out there?
回答1:
Use this code. it will work fine.
$string = preg_replace("/(\{.*\})|}|(\\\S+)/", "", $string);
Note that I added a '/' in the beginning and at the end '/' in the regex.
