Read In Text File Line By Line - Newline Not Being Detected?

I have a php function I wrote that will take a text file and list each line as its own row in a table.The problem is the classic "works fine on my machine", but of course when I ask somebody else to generate the .txt file I am looking for, it keeps on reading in the whole file as 1 line. When I open it in my text editor, it looks just as how I would expect it with a new name on each line, but its the newline character or something throwing it off.So far I have come to the conclusion it might have something to do with whatever text editor they are using on their Mac system.Does this make sense? and is there any easy way to just detect this character that the text editor is recognizing as a new line and replace it with a standard one that php will recognize?UPDATE: Adding the following line solved the issue.

ini_set('auto_detect_line_endings',true);

Function:

function displayTXTList($fileName) {
if(file_exists($fileName)) {
$file = fopen($fileName,'r');

[code]...

Read From The LAST Line Of A CSV File (without Knowing Line Number)?

Is there a way to read from the very last line of a CSV file that has been opened via PHP fopen() ? The trick is that this is a file that has been uploaded by a user, and opened by the server, but could have 100 lines or it could have 100,000. We just need to read from the very last line specifically of the file, which is basically a line containing an array of variables imprinted on the file during upload.

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.

Read A File From Line X To Line Y ?

Is there a way to read a file in PHP5 from line X to line Y into a string, without reading the entire file.I would like to return huge files (10,000+ lines) using ajax requests. Each request will provide the client with additional lines. And due to the fact that the file can reach large sizes, I would like to avoid reading it whole over and over again.

Read A Certain Line From A File

How could you read a certain line from a file, so for example you have a file: Code:

row1column1|row1column2|row1column3|row1column4|row1column5
row2column1|row2column2|row2column3|row2column4|row2column5
row3column1|row3column2|row3column3|row3column4|row3column5
row4column1|row4column2|row4column3|row4column4|row4column5

I know you can read through the lines with fgets() but I want to know whether there is a way to get only a certain line without having to load the whole file (or any other rows) into php (imagine a file with 1000+ rows).

Read First Line Of File?

I'm trying to read the first line of some large files by PHP, which means, the ideal solution does not work:

$fields = explode(",", $content[0]);
QuoteFatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 110 bytes) in C:wampwwwexchangeadminimport.php on line 55

Is there any other way to read only the first line without opening the whole file?

Read Line Comments In INI File?

The parse_ini_file function removes comments when reading configuration files.What would you do to keep the comments that are associated with the next line?For example:

[email]
; Verify that the email's domain has a mail exchange (MX) record.
validate_domain = true

Am thinking of using X(HT)ML and XSLT to transform the content into an INI file (so that the documentation and options can be single sourced). For example:

<h1>email</h1>
<p>Verify that the email's domain has a mail exchange (MX) record.</p>
<dl>
[code]....

Browsers Do Not Read New Line In A File?

I have a password protected text file and to make it password protected, i used a password protector script (which works great) but it required me to rename the text file to .php on my server. This went fine, however, when I open this text file in any browser on windows, i do not seeing any new lines (I used to see them)

I tried writing -"
", "
", "
".

I think it has to do with the browser thinking its a .php file i guess.

Read A Specific Line From A CSV File?

I am attempting to create a request script that will dump requests to the end of the CSV file.

I'm trying to dump the last line of a CSV file into an array, so I can check what the first number is.

Example CSV: (This isn't the actual file)

Code:

000001,Name,ID
000002,Name,ID
000003,Name,ID

So when the php script runs, I can identify the last line:

Code:

$file = "request.csv";
$lines = count(file($file));
echo "There are $lines lines in $file";

Now, I need to take that last line (3 in this case) and somehow pull it into an array, so array[0] = 000003. I can then increment this number and save the new data on a line starting at 000004.

I just can't figure out how to read a specific line from a CSV file.

Read A Line From A Text File Then Delete It?

I have a text file , filled with pipe separated URLs, like this:

[URL]...

etc.

I currently have this code to read each url from the file and pass it to a function:

<?php
$urlarray = explode("|", file_get_contents('urls.txt'));
foreach ($urlarray as $url) {
function1($url);
}
?>

What I want to do next is, after function1() is done, delete that URL from the text file.That way, when the script is done going through all the URLs in urls.txt, this text file should be empty.
