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

May 3, 2009

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)?

Nov 15, 2009

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

Jun 27, 2007

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.

Is there a function to read a file line by line in PHP, i.e. the way you do in Perl like <file_handle> ..... Note that i don't want to use the file() function.. that read entire file into an array and is not suitable when you're reading large files.

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

Jul 8, 2006

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 Line Comments In INI File?

Apr 17, 2010

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>

Browsers Do Not Read New Line In A File?

Jun 14, 2011

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?

Feb 17, 2011

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.

Remove Skip Empty Line When I Read A File?

Apr 23, 2011

reading the official manual, if I want to skip empty line in a txt I just need to call the function file() with FILE_SKIP_EMPTY_LINES; in fact I wrote : $fileArray=file($uploadDirectory.$tracklistFile_name, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);

but It also read empty line. So, in a text like this :

// START OF THE DOCUMENT
aaa
bbb

ccc
ddd

// END OF THE DOCUMENT

in fact sizeof($fileArray) is 6 : it adds the empty lines between bbb and ccc, and the last one. Why?

Read Txt File And Pass Each Line As Variable In A Function

Mar 25, 2007

I'm designing a website that is update several times a week with a new gallery of images.

Each set of images is stored in it's own directory with a page that generates a gallery and textually describes the images in the directory. I want to create a page that reads from a list of the image directories and dynamically generates a link to each gallerey, 10 to a page.

something like this:

directorylist.txt

index.php reads directorylist.txt, places the first gallery listed at the top of the page, then 9 more links to the next 9 galleries. At the bottom of this page, links to the pages that contain galleries 11-20, 21-30, etc.

I have already created functions that take the gallery ID and generate the links, I just can't seem to figure out how to read from the text file, then generate the links in my main pages.

Read An External File Every Set Amount Of Time?

I am writing a script where it checks for an updated version from an external server. I use this code in the config.php file to check for latest version.

$data = get_theme_data('http://externalhost.com/style.css');
$latest_version = $data['Version'];
define('LATEST_VERSION', $latest_version);

This is fine and I can fetch the latest version (get_theme_data is WordPress function) but the problem is that it will be executed on every single load which I do not want. I also do not want to only check when a form is submitted for example. Alternatively I was looking into some sort of method to cache the result or maybe check the version every set amount of hours?

Ajax Jquery - Post Csv File One Line At A Time

Jul 15, 2011

I want to do this:

user load a csv file it reads the data one by one,php do the processing, it takes quite some time.php enter the process to mysql

problems are:

csv file is too large, so the php hit the 30 secs time limit .the processed data should be entered to sql in order and one by one running just the php, the connection to mysql can't keep up, so far i need to separate the csv to 30 lines per file so it could be entered correctly to mysql.

I think combining with jquery:

jquery reads the file
jquery pause 1 second per csv line
jquery is client side so it won't have time limitation
jquery then call php which in turn will send to mysql

I'm stuck with jquery, because it sends the data in csv in non-ordered way.What I need help is to pause the jquery.post one by one in example 1 second interval each.here's the code that i've come up so far. i need the "pausing" effect for each post

<script>
$(function () {
var o1;[code]...

and this is the 'test2.php' file content. it's just an example of what i will do, the real code is of course more complex:

if ($_POST){
@$_POST['jquery']!=''?$jquery=$_POST['jquery']:$jquery='';

At the moment im reading in the WHOLE log file and sorting it into an array and passing the neccesary data to mysql. Easy peasy.

But my boss has pointed out to me that as the site gets more and more traffic the log gets bigger, and if it gets to big the servers memory will overload, and we all know what happens then!

So what I need to do is read in the file one line at a time. and compare the timestamp to the last time the script was run. If the timestamp in the log is less than the last timestamp for when the file was run dont read it. If it is more than defiently read it. Code:
