andrewgarn Posted October 16, 2008 Share Posted October 16, 2008 My project I was attempting is an automatic php system which takes a user submitted powerpoint file, opens it and extracts keywords. These could then be added to a database and be made searchable. What I have done so far, is open a powerpoint file in php. split the data by carriage returns and spaces removed parts under 5 characters and over 15. removed words from string that contain characters other than A-Za-z I started off with the original data extracted which was around 2mb of text. After doing the steps above i'm left with 3.8kb of keywords from inside the powerpoint file. But I still have "junk" pieces of data: agilgdyj lhcls tdmqjx qokkjf xbxan bwpgt cmucj zqbbrp bgac jwmlnx ufsxt photoshop maasp dpkka wpedb kczbb huqz jjbnf jcztpf hqvoi ccpau vljxa pyfjm mhhvb hyfkk rdqhk liwip aezeg ejyow jsuznw kuqsu syktt zctbq upijhvb lbdxn sewsgc tmdec ttjklz lrvht dqypb omqzpng decdj nskxjr mpcvx vccmath puddg laapcr uteqqo svzyo urgvub yvcro ihxjr ebvve rnngz zrudu irtlb cddzo yqxgy ngzro aktpk yahuc ndelz uzqtk olpar aqrty bnxpuygd vltxj citpj ngwso beysx bexpq Would there be any way further to remove these junk pieces?

MadTechie Posted October 16, 2008 Share Posted October 16, 2008 Why did you start a new thread ?

And i'm afraid i dont understand COM or have a windows server to host the file on.
