Re: [PHP] php, text file, and mysql
You can use a string to keep the file content. And then put it the mysql(probably a BLOB field) Best regards, Andrey Hristov IcyGEN Corporation On Thursday 07 March 2002 11:30 pm, you wrote: hello everyone. i'm wondering if i can do the following: FIRST, using php, can i create/generate a text file on-the-fly (not saved to a server) THEN, insert the actual text file (and not its contents) into a mysql database. many thanks in advance, gregory hernandez [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Sorry, but I don't really understand the question. If you are creating or generating a text file, the word file indicates that this is represented by an entity in a filesystem -- thus, it would be saved to a server. Are you asking if you can create/generate text without saving it as a file on the server, but rather just storing the text in memory temporarily? If so, then yes -- -- and the second question I haven't really figured out either. You want to store a text file into a MySQL database but not the contents of that file? It seems like in the first question you want to have contents without a file, and in the second you want a file without contents! :) Unless someone else figures out what you want and helps you, ask again but describe what you want a little bit more.

Re: [PHP] php, text file, and mysql
Erik: thank for answering my first question: the word file indicates that this is represented by an entity in a filesystem -- thus, it would be saved to a server. now let me rephrase the second part. what i meant to say was the following: can i insert the actual file (i.e. document.txt, of course with it contents) into a mysql? in other words, i don't want to read the contents of the file and insert the contents into a field in mysql. i want to insert the actual file into the database. is this possible? thanks again in advance. gregory on 3/7/02 12:44 PM, Erik Price at [EMAIL PROTECTED] wrote: On Thursday, March 7, 2002, at 04:30 PM, gregory hernandez wrote: i'm wondering if i can do the following: FIRST, using php, can i create/generate a text file on-the-fly (not saved to a server) THEN, insert the actual text file (and not its contents) into a mysql database.

Re: [PHP] php, text file, and mysql
Are you planning on using MySQL as a filesystem? There seems to be great confusion here.

Yes you can, though it might be an inefficient way of doing it unless you have some reason to do it this way. Look into the column type BLOB (binary large object), it lets you store binary large objects, such as images or files or anything, really. Why inefficient? Well, for one thing, BLOBs don't retrieve as quickly as regular fields, for reasons I don't altogether know. Also, you won't be able to form a query to search for any characteristics of a BLOB, since MySQL will treat the BLOB as a BLOB and doesn't try to imagine what's inside it -- as opposed to, say, a VARCHAR column. There is also a TEXT column type for very long text strings, and I forget whether or not the contents of these can be used in queries -- can someone please confirm this? But basically, almost any other column type is valid subject matter for forming queries. But for storing images and PDFs or other binary data, there's no other way. Note that many MySQL wizards will recommend that instead of storing binary data in a database, use a filesystem to store the data and then use the database to create a sort of directory for quickly locating those files in the filesystem, remembering the path to the file or something. I think this is how a lot of web sites incorporate graphic content in with their database (text) content (including mine). Erik Erik Price Web Developer Temp Media Lab, H.H.

RE: [PHP] php, text file, and mysql
But for storing images and PDFs or other binary data, there's no other way. Actually, after having some problems with BLOB columns when mysqldump'ing and moving the data into a new database, I did find another way. I borrowed a trick from MIME mail handling, and base64_encod'ed, then chunk_split'ed the data. This makes it very text-field friendly. Note that many MySQL wizards will recommend that instead of storing binary data in a database, use a filesystem to store the data and then use the database to create a sort of directory for quickly locating those files in the filesystem, There's a problem with this, it assumes that you only use one filesystem for your site. In the case of Melbourne IT / INWW, we have 5 or 6 web servers that load balance. If a user uploads data and we copy it to the filesystem, then it's only available on 1 web server. This is why we put it in the database. :) Jason -- Jason Murray [EMAIL PROTECTED] Web Developer, Melbourne IT Work now, freak later! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] php, text file, and mysql
Good day, This isn't really on the topic of PHP. But, to answer your question- yes, MySQL will let you do lots of neat things with those large text fields, like looking for substrings and such. If you want to store some text information, even that which might have special characters, line feeds and so forth, the TEXT field is definately the way to go.
