when users type in a keyword i want my search bar on my site to grab info from a file ive uploaded to the ftp and tshow the info from the file. what program will do this, php, html etc. also any tips
I agree with Nathan, PHP is better than others which you mentioned because this is the easy language which can easily use for this purpose.
You don't upload a file to the site, you put the data into a database on the site. Then you use AJAX to do incremental selects from the database. Go to Google and start typing in a search term. You'll see how it works. What language do you use? (You don't use any program, except the one you - or someone you hire - writes.) The language used on the site. So if you're hosted on a Windows computer it's most likely going to be VB. If it's a Linux box it'll most likely be PHP. But it could also be Python, RoR or a few other languages. You use what's there. (PHP is most common, since most sites run on Linux boxes, and most hosting companies include PHP on their Linux boxes.)
Well friend i also want to know. That PHP learning is good because i am also going to learn PHP after few days. If you know other then please suggest me.
