I need to delete the last line of the flat file before I append though.

How do i do that?

Processing A Text File, Line By Line With Fgets...
is there anyone out there who can help me out with this thing? goin nuts over here. i got a long text file, comma delimeted with each line representing a product i need to import..

i've done a bunch of other things with this file so far using the method below, but now i want to change the price of each item by exploding a line, changing the price element, then imploding back to a string for 'fputs' in my destination file.

It works on the first line of text fine, and loops through all the other lines and 'fputs' them as well with no errors, but doesn't operate on the price like with the first line. all i can see is that my $line array keeps adding to the end instead of resetting.. i tried using reset and unset, but wasn't working either, was probably doing it wrong.. am i missing something obvious?

Read Text File Line By Line
I have been given a textfile which contains data on 1000 businesses.  Each line contains a name and a code which are seperated by a comma.  The code below allows me to display the entire textfile but I want to read in the values from each line and store these in a database.

$filename = "businesses.txt";
$fileToOpen = fopen($filename,"r");
$content = fread($fileToOpen, filesize($filename));
$content = nl2br($content);
fclose($fileToOpen);
echo($content);

Does anyone know how I can read the data in line by line so that I can store it in a database.

New Line In Text File
I'm trying to create a text file in php to generate a playlist. The problem is that I cannot manage to create a new line in the text file. Using /n still places text in the same line and just inserts a symbol to indicate the 'new line'. Using

just works when viewing the document in HTML (which is not what i need in this case). But what I want is to physically insert a new line in the text file so that when i open the generated file using notepad i see that there are actually new lines in the document and so that the playlist can be read normally with a music player.

Reading Strings In Text File (1 Per Line)
I am trying to take a text file containing a list of email addresses (1 per line), and insert each line as a new item in mySQL.

I know how to do most of the php and the mySQL, but I am not sure about the syntax of the line to return the string from "line x" of the tex tfile.

From the php doc. I have this code to read the full contents of my text file:

// get contents of a file into a string
$filename = "/usr/local/something.txt";
$fd = fopen ($filename, "r");
$contents = fread ($fd, filesize ($filename));
fclose ($fd);

My question, clearly is:
then how do I split $contents into an array so that $emails[150] could return the email number 150?

note: one of the array $arrText, eg. $arrText[3] = "line 3" . "n";
the next array $arrText[4] will NOT start on a new line, it will just joint the rrText[3].

Removing Line Breaks In Reading Text File
When I read in a text file seperated by | delimiter, all is well except in the case of data posted to that text file from a Textarea within a Form. When the user hits the Return key once, a new line is ultimately created in the final file read; when the user does a 2nd or subsequent CR, there are multiple blank lines on the file as it is echoed into a web page (in fact, 7 <BR>s in a row).

I've tried str_replace to no effect ...is it a PHP error or is it something logical I've missed. Lines 5a, 5b, 5c, 5d are the results of a Textarea submission - they aer all one field - that have been seperated by a carriage return in an html form posting to a text file: Code:

Line-by-line Text Parsing
I'm moving part of a program from Java to PHP, and there's some functionality I can't quite figure out how to translate. I'm looking for a way to parse text files line-by-line, and searching around I've found out how to do that, but I can't figure out how to control the code so that I can skip past certain lines. For example, my Java code works like this:

while (line != null) {
// handle empty lines and special lines
if (line.equals("")) { // skip empty lines

line = in.readLine();
continue;
} else if (line.contains("Stimuli;")) {
// populate the names array based on line following "Stimuli;"
line = in.readLine();
names = line.split(" ");
line = in.readLine();

How To Delete Only Certain Text In A Mysql Row?
I have a table setup that has a column setup as friends and users can add friends to this column no problem.

What I would like to know is how to delete only certain parts of the text of the row/cell where their friends are stored.

The friends text is seperated by the following :

" , "

That is a space on either side and comma in the middle of the space.

I know how to explode the results and put into an array to display the reuslts, but is there a way to delete only one of the friends if the text is as follows.

Is it possible to do this or should I just update the whole cell without the array[$i] result being the friend?

Reading A File Line By Line
I had a bit of code to read a file line by line looking for a match to a variable. I was getting errors at the end of the while loop. It said something to the effect that one of the parameters for the strpos test was missing. I thought maybe I had some empty lines at the end of the file. Is there a better way to rip through a file to test for a match?

$handle = fopen($_SERVER['DOCUMENT_ROOT']."/data.txt", "r");
while (!feof($handle)) {
$buffer = fgets($handle);
$pos = strpos(trim($buffer), trim($$name));
}

$handle = fopen($_SERVER['DOCUMENT_ROOT']."/data.txt", "r");

How To Capture The First Line Of A Text, Then The Rest?

Im planning to have each review as one txt file, that I write "by hand" with the first line as the title. (If anyone knows of a better, smarter and faster way to do this, let me know, i'm new with PHP. With MySQL or whatever.)

The script should first parse the first line of the .txt file and use that one for title, so i can use a different size of text for it, and then it should parse the rest of the file and use for body text.

Inserting Spaces Into A Line Of Text
Is there a way to insert a space every 3 characters (or any given number) in a line of text? I am getting data from the NWS site and if their data is a 2 digit number there is a space between it and the next data. but if the number is a 3 digit number, the first digit takes up the place that was a space. like the example below. Code:

TMP 64 69 80 89 93 87 78 70 65 71 84 94 98 92 82 74 69 75 89103 85

I need to find a way to get it to look like this by I am assuming adding a space every 3 characters. Code:

TMP 64 69 80 89 93 87 78 70 65 71 84 94 98 92 82 74 69 75 89 103 85

I think that php is reading the run together numbers as one 5 digit number because there is no space between them. If i could as a rule just count over 3 (or whatever) and insert a space it would not matter if the entire line contained 3 digit numbers.
