I need to open a CSV File with 60+ rows and three columns.
the third column in the file is a link. I need to add a String (ex.: "/ref="04" ") at the end of every Link and then safe it.
file looks like this
Products--------Description-------Link
Apple-----------blablabla---------http://www-anylink.com
Banana----------blablabla---------http://www-anylink.com
Should look like this afterwards (adding "/ref04" to the end of links)
Products--------Description-------Link
Apple-----------blablabla---------http://www-anylink.com/ref04
Banana----------blablabla---------http://www-anylink.com/ref04
SO the file i need to edit is for an affiliate program and i have never used PHP before. I figured out how to open and safe files, but i don't know how to edit it and put all together.
It should not be that hard but i can not find any example in the Internet.
Can anyone please help me i cant wrap my head around programing. I am trying but its hard.

I have been trying for a while now to import this kind of file to phpmyadmin and with external PHP infile load code, however I cant seem to get the result I would like. I'm not too sure whether I am putting the correct data within the format specific options.
Columns separated with: (space character)
Columns enclosed with: -
Columns escaped with: -
Lines terminated with: auto (\n)
Could someone propose a suggestion as what I should do? The snippet of text below is what the text file looks like (without the bullet points).
Perhaps phpmyadmin is not the way to go?
I would show you guys pictures but I don't have the reputation...yet.
If this helps, I have a link from where I got the dataset:
- https://snap.stanford.edu/data/web-Amazon.html
The layout is shown in the link, I would use Python if need be, though I don't have the experience with that language, I'm willing to use a parser which is provided in the link (wouldn't know where to start).

For a project, I need to get some word definitions in a database. All the definitions can be found on multiple DB files, but the DB files that I got are for a C language program and are in the form of ASCII (I believe). I need to somehow phrase thorough the files, line by line add the data into a MySQL database.
I would prefer using PHP and/or MySQL.
I tried writing a PHP script to go through and do it, but it timed-out and is intensive on my system and in most cases don't complete.
I heard about LOAD DATA INFILE from MySQL but have no clue how to use it with this.
The file names change for each file and do not have a specific extension, however, all of them can be read from a text file, and I am sure they are all the same in terms of content.
I uploaded the contents of one file here.
You can see that some lines are useless, but the lines starting with { are good and the pattern is essentially the first word is the dictionary term, and the content within () are the definitions. The parts within the "" are sample sentences.
All I need to extract are the terms, definitions and sentences.
The definitions are provided by Princeton University and the license is open source (and I will be crediting them).
Unless you want to reinvent the wheel I would go with something like wordnet2sql. It will output an SQL script that you can use to create your MySQL tables.
You can find the database specifications on princeton's website.
LOAD DATA is useful for csv files but not so much for special database formats.
There are quite a few different threads about this similar topic, yet I have not been able to fully comprehend a solution to my problem.
What I'd like to do is quite simple, I have a flat-file db, with data stored like this -
$username:$worldLocation:$resources
The issue is I would like to have a submit data html page that would update this line based upon a search of the term using php
search db for - $worldLocation
if $worldLocation found
replace entire line with $username:$worldLocation:$updatedResources
I know there should be a fairly easy way to get this done but I am unable to figure it out at the moment, I will keep trying as this post is up but if you know a way that I could use I would greatly appreciate the help.
Thank you
I always loved c, and functions that came into php from c.
Check out fscanf and fprintf.
These will make your life easier while reading writing in a format. Like say:
$filehandle = fopen("file.txt", "c");
while($values = fscanf($filehandle, "%s\t%s\t%s\n")){
list($a, $b, $c) = $values;
// do something with a,b,c
}
Also, there is no performance workaround for avoiding reading the entire file into memory -> changing one line -> writing the entire file. You have to do it.
This is as efficient as you can get. Because you most probably using native c code since I read some where that php just wraps c's functions in these cases.
You like the hard way so be it....
Make each line the same length. Add space, tab, capital X etc to fill in the blanks
When you want to replace the line, find it and as each line is of a fixed length you can replace it.
For speed and less hassle use a database (even SQLLite)
If you're committed to the flat file, the simplest thing is iterating through each line, writing a new file & changing the one that matches.
Yeah, it sucks.
I'd strongly recommend switching over to a 'proper' database. If you're concerned about resources or the complexity of running a server, you can look into SQLite or Berkeley DB. Both of these use a database that is 'just a file', removing the issue of installing and maintaining a DB server, but still you the ability to quickly & easily search, replace and delete individual records. If you still need the flat file for some other reason, you can easily write some import/export routines.
Another interesting possibility, if you want to be creative, would be to look at your filesystem as a database. Give each user a directory. In each directory, have a file for locations. In each file, update the resources. This means that, to insert a row, you just write to a new file. To update a file, you just rewrite a single file. Deleting a user is just nuking a directory. Sure, there's a bit more overhead in slurping the whole thing into memory.
Other ways of solving the problem might be to make your flat-file write-only, since appending to the end of a file is a trivial operation. You then create a second file that lists "dead" line numbers that should be ignored when reading the flat file. Similarly, you could easily "X" out the existing lines (which, again, is far easier than trying to update lines in a file that might not be the same length) and append your new data to the end.
Those second two ideas aren't really meant to be practical solutions as much as they are to show you that there's always more than one way to solve a problem.
ok.... after a few hours work..this example woorked fine for me...
I intended to code an editing tool...and use it for password update..and it did the
trick!
Not only does this page send and email to user (sorry...address harcoded to avoid
posting aditional code) with new password...but it also edits entry for thew user
and re-writes all file info in new file...
when done, it obviously swaps filenames, storing old file as usuarios_old.txt.
grab the code here (sorry stackoverflow got VERY picky about code posting)
https://www.iot-argentina.xyz/edit_flat_databse.txt
Is that what you are location for :
update `field` from `table` set `field to replace` = '$username:$worldlocation:$updatesResources' where `field` = '$worldLocation';
I am new in coding and sufferin from some basic issues. I searched for a topic to find the answer that I need but I could not find. I've been trying to write and searching codes for writting into xls file for 3 days but could not find a suitable one. The problem is:
I created a page with textareas and submit/reset button like that and I've got an excel table in document classgrades.xls. The colums of that table are named Name, Midterm1, Midterm2, Final, Attendance and Average.
Now, I am trying to write a code which automatically adds a new row and writes user inputs from textares into the excel table. If you help I appreciate very much and if you write the code briefly I can understand better.
The class I use to modify Excel documents is PHPExcel. Was at http://phpexcel.codeplex.com/ but I just googled and it's moved to GitHib https://github.com/PHPOffice/PHPExcel.
Small warning: I have found it occasionnally buggy (turn off "NOTICE" and "WARNING" errors before diving in, for example - or at least you did when I last used it) but otherwise it's easy to use.
It has some nice classes to navigate the workbooks and add rows. No point quoting examples here as there are lots of examples in the "test" section. https://github.com/PHPOffice/PHPExcel/tree/develop/Tests Use those and piece together what you need.
I want to get content of a textbox posted on other page without database, means m creating a complaint box, and complaint should be posted on admin page. Every new complain should b at top and others below it. can you please help.
When you store some data, you are creating Data-Base as well
If you don't want to use SQL or similar (liteSQL, XML file DB,...)
you can use directory structure like this
/[year]
/[year]/[month]
/[year]/[month]/[day]
/[year]/[month]/[day]/[exact_timestamp]+[random_hash].[file_extension]
and save them in file structure, each complain as standalone text file
It may be best to just have one, delimited file. Then you only have to read from one place. Depending on the frequency of your complaints, you may want to have one file per day.
To avoid strange locking issues maybe do something similar to what Marek suggested and temporarily store each complaint in a standalone file. Then run a CRON to concatenate them every so often
