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'm currently attempting to come up with a solution to the following problem:
I have been tasked with parsing large (+-3500 Lines 300kb) pipe delimited text files and comparing them line by line to corresponding codes within our database. An example of a file would be:
File name: 015_A.txt
File content (example shows only 4 lines):
015|6999|Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.|1|1|0|0|2016/01/01
015|3715|It has roots in a piece of classical Latin literature from 45 BC|1|1|213.5|213.5|2016/01/01
015|3724|Making it over 2000 years old.|1|1|617.4|617.4|2016/01/01
015|4028|Words will go here.|1|1|74|74|2016/01/01
I will be providing a web interface which I have already built to allow a file to be selected from the browser and then uploaded to the server.
Using the above example pipe file I will only be using these:
Code (using above line 1 as an example: 6999)
Price (using above line 1 as an example: 0)
I would then (to my mind not sure if this is best method) need to run a query (our DB is MSSQL) for each line, example:
SELECT t.Price
FROM table t
WHERE t.code = '6999'
If t.Price === 0 then line 1 has passed. As it is equal to the source file.
This is where I believe I just needed to ask some advice as I am sure there are many ways to tackle this problem, I would just like to, if possible be pointed in the direction of doing this in an efficient manner. (Example best method of parsing the file? Do I run a query per code or rather do a SQL statement using an IN clause and then compare every code and price? Should I scrap this idea and use some form of pure SQL tool bearing in mind I have pipe file to deal with / import.)
Any advice would be greatly appreciated.
Your story appears to end somewhat prematurely. Is the only thing this script should do is check the values in the database match the files in the file? If so, it would be simpler just to extract the data from the database and overwrite the file. If not, then this implies you need to retain some record of the variations.
This has some bearing on the approach taken to the reconcilliation; running 3500 queries against the database is going to take some time - mostly spent on the network and in query parsing (i.e. wasted). OTOH comparing 3500 records in a single SELECT to find mismatches will take no time at all.
The problem is that your data is out at the client and uploading via a browser only gets it halfway to the database. If you create another table on the database (not a temporary table - add a column to represent the file) it is possible to INSERT multiple rows in a single DML statement, but really you should batch them up in lots of 100 or so records, meaning you only need to execute 36 queries to complete the operation - and you've got a record of the data in the database which simplifies how you report the mismatches.
You probably should not use the DBMS supplied utilities for direct import unless you ABSOLUTELY trust the source data.
I need help parsing the following a CSV file in PHP, so I can insert the contents into a database.
I know I use file_get_contents() but after that I feel a bit lost.
What I'd like to store.
Collection1 - events.text & date
Collection2 - position & name.text & total
I'm not sure how best structure the data to insert into a database table.
"**collection1**"
"events.href","**events.text**","**date**","index","url"
"tur.com/events/classic.html","John Deere Classic","Thursday Jul 9
- Sunday Jul 12, 2015","1","tur.com/r.html"
"collection2"
"**position**","name.href","**name.text**","**total**","index","url"
"--","javascript:void(0);","Scott","--","2","tur.com/r.html"
"--","javascript:void(0);","Billy","--","3","tur.com/r.html"
"--","javascript:void(0);","Jon","--","4","tur.com/r.html"
"--","javascript:void(0);","Bill","--","5","tur.com/r.html"
"--","javascript:void(0);","Tim","--","6","tur.com/r.html"
"--","javascript:void(0);","Carlos","--","7","tur.com/r.html"
"--","javascript:void(0);","Robert","--","8","tur.com/r.html"
"--","javascript:void(0);","Rod","--","9","tur.com/r.html"
As per your previous question, I think this needs to be broken down into sections. As it stands it is rather too broad to answer.
Read the information using file_get_contents(). Make sure this works first, by echoing it to the console. (It sounded from your other question that you felt this would not work if the URL does not have a .csv suffix. It should work regardless of the file extension - try it. If it fails it may be dependent on cookies or JavaScript or some other problem).
Design and create your table structure in MySQL. It seems like you have two tables. They should both have a primary key. Are they related in some fashion? If so, perhaps one has a foreign key to the other one?
Explode your text file on the new line character and loop across the resulting array of lines.
If your CSV data has a title row in the first row position, delete that from your array.
For each line, read the elements of interest using PHP's build-in CSV parsing functions, and store them in variables.
Pass these variables to a custom function that saves the data.
For each save, you'll need to do an INSERT. I recommend using PDO here. Make sure you bind your parameters.
Where you get stuck on a specific problem, you can ask a new and focussed question. At present, the task is to break things down into discrete and researchable pieces.
One trick worth remembering is this shortcut to the PHP manual. If you do not know how fgetcsv works, for example, type php.net/fgetcsv into your browser address bar, and the PHP site will find the function for you. The documentation is excellent.
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.
I want to display a large amount of text using a php echo command. I have that data stored in mysql database table in a text field. What i want to achieve is that the data should be displayed in the same manner in which i store it in the text field.
for example:
As entered in Mysql table by its Interface One reason people lie is to achieve personal power.
Achieving personal power is helpful for someone who pretends to be more confident than he really is. For example, one of my friends threw a party at his house last month. He asked me to come to his party and bring a date.
Although this lie helped me at the time, since then it has made me look down on myself.
Should be displayed exactly as the above rather than:

Any ideas/tips on how this can be achieved?
I know that i can manually insert html tags between the text for formatting but i dont want to manually do so. Any way around?
nl2br($foo); will automatically add a <br> tag wherever there is a linebreak in $foo. You can echo nl2br($foo);.
As an alternative, try the <pre> tag. <pre><?php echo $foo; ?></pre>. You many need more styling, but it will preserve whitespace like your linebreaks.
My solution is:
I'm using GWT TextArea textAreaWidget widget.
Before insert the TextArea string to MySQL table I replace all line change and tab characters:
-new line
String toInsert=textAreaWidget.getText().replaceAll(Character.toString((char) 10), "\n\r"));
-tab
String toInsert=textAreaWidget.getText().replaceAll(Character.toString((char) 9), "\t"));
