PHP - [r/w Text Files] Way Easy Text File Problem
Ok i have been working on this for a day+ now. here is my delema
simple .ini text file. when a user makes a change (via html form) it makes the correct adjustments. problem is the newline issue 1. if i put a "\n" at the end (when using fputs) works great, except everytime they edit the file it keeps adding a new line (i.e. 10 edits there are now 10 blank lines!!!!) 2. if i leave off the "\n" it appends the next "fgets" to that lilne making a mess Code: [Select] ##-- Loop thruoght the ORIGINAL file while( ! feof($old)) { ##-- Get a line of text $aline = fgets($old); ##-- We only need to check for "=" if(strpos($aline,"=") > 0 ) { ##-- Write NEW data to tmp file fputs($tmp,$info[$i]." = ".$rslt[$i]."\n"); $i++; } ##-- No Match else { fputs($tmp,$aline."\n"); }//Checking for match }//while eof(old) what in the world is making this such a big deal. i dont remember having this issue in the past I tried opening with w+, and just w on the temp file a typical text line would be some fieldname = some value the scipt cycles through the file ignoring comments that are "#" ps the tmp file will overwrite the origianl once complete all i really want to know is WHY i cant get the newline to work, and what is the suggested fix EDIT: i just tried PHP_EOL and it still appends another newline Similar TutorialsHi, I am writing several scripts and some are used to amend extra information to a text file. However, I added a hyperlink to the text file so that the user can go back to a page where they can add extra information. However, since I have done this every time I amend more text to the text file, the extra text appears below the hyperlink rather than above it, and I was wondering if there was a way around this. My amend code is as follows: Code: [Select] <html> <head> <title>Amend File</title> <link rel="stylesheet" type="text/css" a href="rcm/stylesheet.css"> </head> <?php if($_POST['append'] !=null) { $filename="C:/xampp/htdocs/rcm/denman2.txt"; $file=fopen($filename, "a"); $msg="<p>Updated Information: " .$_POST['append']. "</p><br>"; fputs ($file, $msg); fclose($file); } ?> <body> <h1>Do you want to append to a document?</h1> Enter Updated Information: <form action="amendfile2.php" method="post"> <input type="text" size="40" name="append"><br><br> <input type="submit" value="Add updated information to report"> </form> <form action="viewfile3.php" method="post"> <input type="submit" size="40" value="View Web Blog"> </form> <form action="loginform.php" method="post"> <input type="submit" value="Click here to go to the Log In Screen"> </form> </body></html> And my text file is as follows: Code: [Select] <h1>Accident Report</h1> <p>First Name: Andrew Last Name: Denman Age: 18 Complete Weeks Since Accident: 2<br> <a href="amendfile2.php">Amend to this file</a> Any help would be appreciated I currently am working on a project where I code a "simple" telephone directory. There are three main tasks that it needs to do: 1. Directory.php(index page) has a "First Name" and "Last Name" field and a search button. When a name is searched from the directory.txt file, it displays First Name, Last Name, Address, City, State, Zip and phone in findinfo.php in designated text boxes...first name, last name, etc. 2. From the findinfo.php, like previously stated, the users information is listed in the appropriate text boxes. From there, there is an update button that will overwrite the user's information to directory.txt if that button is selected. It will then say the write was sucessful. 3. (completed this step) From the index page, there is a link that will take you to addnew.php where you enter First Name, Last Name, Address, City, State, Zip and phone in a web form and write it to directory.txt. This is the php code for the third step: <?php $newentryfile = fopen("directory.txt", "a+"); $firstname = $_POST['fname']; $lastname = $_POST['lname']; $address = $_POST['address']; $city = $_POST['city']; $state = $_POST['state']; $zip = $_POST['zip']; $phone = $_POST['phone']; $newentry = "$firstname $lastname\n\r $address\n\r $city, $state $zip\n\r $phone\n\r"; if (flock($newentryfile, LOCK_EX)) { if (fwrite($newentryfile, $newentry) > 0) echo "<p>" . stripslashes($firstname) . " " . stripslashes($lastname) . " has been added to the directory.</p>"; else echo "<p>Registration error!</p>"; flock($newentryfile, LOCK_UN); } else echo "<p>Cannot write to the file. Please try again later</p>"; fclose($newentryfile); if(empty($firstname) || empty($lastname) || empty($address) || empty($city) || empty ($state) || empty($zip) || empty($phone)) { echo "<p>Please go back and fill out all fields.</p>"; } ?> So to sum it all up, what would be my best approach? I am totally stumped and not sure which function to use. Should I work my way from step 1 to step 2? I see it as when I do the search for the name from directory.php, it takes me to findinfo.php, listing the users information in the text boxes. From there, if I needed to, having the user's information already listed I could hit the update button to overwrite the new information to directory.txt. Doing the update when then tell me that the write was successful. I have literally been scouring the internet for hours. What would be the best function to do this? I hope I was clear enough. Please help me out and thank you for your time. Please help and amend the code Save without repetition required $read[0] I hope that my example is clear to you I apologize for bothering you. I am not good in English
<?php
$fileLocation = getenv("DOCUMENT_ROOT") . "/rt.txt";
$file = fopen($fileLocation,"a");
$n1 = $_POST['n1'];
$n2 = $_POST['n2'];
for($i = 0; $i < count($file); $i++){
$read = explode("|", $file[$i]);
if($n1 == $read[0]){
echo 'Repetition';
}
else
{
fwrite($file,$n1.'|'.$n2."\r\n");
}
ok, I am hoping the code is self explanatory... but if not, I'm creating a script which I will be using for something else. Basically it says if OS and browser show code under... I am looking for two things. 1. Is there a way to make it so that it can pull from a list and show that if HTTP_USER_AGENT comes back with a specific output, to say you are using X OS with Y browser? 2. The last bit, it is meant to say, if not any of the options show the info below. For some reason it's not doing that... can someone please tell me why? Thanks. Code: [Select] <?php //Operating Systems function xp(){return(eregi("Windows NT 5.1", $_SERVER['HTTP_USER_AGENT']));} function vista(){return(eregi("Windows NT 6.0", $_SERVER['HTTP_USER_AGENT']));} function win7(){return(eregi("Windows NT 6.1", $_SERVER['HTTP_USER_AGENT']));} function ubuntu(){return(eregi("Ubuntu/", $_SERVER['HTTP_USER_AGENT']));} //Web Browsers function chrome(){ return(eregi("Chrome/", $_SERVER['HTTP_USER_AGENT']));} function safari(){ return(eregi("Safari/", $_SERVER['HTTP_USER_AGENT']));} function firefox(){ return(eregi("Firefox/", $_SERVER['HTTP_USER_AGENT']));} function ie9(){ return(eregi("MSIE 9.0", $_SERVER['HTTP_USER_AGENT']));} function ie8(){ return(eregi("MSIE 8.0", $_SERVER['HTTP_USER_AGENT']));} // do something if XP and Chrome if(xp() && chrome()){echo 'You are using Windows XP with a Chrome web Browser';} // do something if XP and IE8 if(xp() && ie8()){echo 'You are using Windows XP with a Internet Explorer 8 web Browser';} // do something if Windows 7 and IE9 if(win7() && ie9()){echo 'You are using Windows 7 with a Internet Explorer 9 web Browser';} // do something if Windows Vista and IE9 if(vista() && ie9()){echo 'You are using Windows Vista with a Internet Explorer 9 web Browser';} // do something if Windows Vista and IE8 if(vista() && ie8()){echo 'You are using Windows Vista with a Internet Explorer 8 web Browser';} // do something if Ubuntu and Firefox if(ubuntu() && firefox()){echo 'You are using Ubuntu with a Firefox web Browser';} if(!ubuntu() || !xp() || !vista() || !win7() || !firefox() || !chrome() || !safari() || !ie9() || !ie8()){ echo'<strong>'; echo '<br />' . $_SERVER['HTTP_USER_AGENT'] .

Every text file has an array like this, (numbers representing the data) and i'm trying to make it so i can access every array an combine it. So in the end i want to know how many text files have the number "6" for the 6th array and so on. I'm pretty new at PHP, so please be detailed. Hey, I'm looking for some PHP code which can read a certain text file i have. I need to get certain information from this text file. This is how the text file looks like: metadataIngester: now executing performAction with token: 9188147351 metadataIngester: result of performAction with token:9188147351 metadataIngester: runtime (ms) for token 9188147351: 9953 inferencer: now executing performAction with token:9188147351 inferencer: result of performAction with token:9188147351 inferencer: runtime (ms) for token 9188147351: 10903 transcoder: now executing performAction with token:9188147351 transcoder: result of performAction with token:9188147351 transcoder: runtime (ms) for token 9188147351: 65456 transcoder: now executing performAction with token:9188147351 transcoder: result of performAction with token:9188147351 transcoder: runtime (ms) for token 9188147351: 83128 streamingServerTransfer: now executing performAction with token:9188147351 streamingServerTransfer: result of performAction with token:9188147351 streamingServerTransfer: runtime (ms) for token 9188147351: 12187 middlewa now executing performAction with token:9188147351 middlewa result of performAction with token:9188147351 middlewa runtime (ms) for token 9188147351: 28148 Now, there are more parts like this with an other tokenID & runtimes. I need to get the runtime for each token (in this example it will be 9953 + 10903 + 65456 + 83128 + 12187 + 28148 = 209775 (ms)). I need PHP to display the tokenID + the total time per token. Just thinking last night trying to speed some things up, how hard is it to have a text file on the server that can only be edited by PHP? Or is there a way of making a folder unreadable to anyone?, this way I could have all the text files in the non-readable (non-viewable) folder so no user could edit them? James Hey! I have a bunch of text files with one line of text ex. SHS9GW34 I'm trying to write a little php script on my local machine that will take all the files and put all the different codes in the same files in this kind of format: RGDGIDSG453 EOHBDSBN453 ERGD4535355 etc etc Thanks I have some fairly small text files (2K) which are parsed where certain deliminated fields are replaced with values provided in an associated array. There will typically be less than 5 replaced fields, and I plan on using preg_replace_callback to find and replace them.
I am contemplating caching the files after being parsed (note that they will only be accessed by PHP, and not directly by Apache).
Do you think doing so will provide any significant performance improvement?
If I do go this route, I would like thoughts on how to proceed. I am thinking something like the following:
Append the filename along with the serialized value of the array, and hash it using md5().
Store the parsed file using name "file_".$hash
Get the modification time of the newly created file using filemtime(), and store the value in a new file called "time_".$hash.
bla bla bla
When the next request comes in to parse a file, create the hash again.
If the file exists for the given hash name, and the time file matches filemtime(), use that file, else parse the original file.
Is this a good approach?
Hi guys, im logging activity on my site to text files using; Code: [Select] date_default_timezone_set('GMT'); $LogFileLocation = "xxxxxxxx.log"; $fh = fopen($_SERVER['DOCUMENT_ROOT'].$LogFileLocation,'at'); fwrite($fh,date('d.M.Y H:i:s')."\t".$_SERVER['REMOTE_ADDR']."\t".$_SERVER['REQUEST_URI']."\n"); fclose($fh); This is write something like; [date] [time] [ip address] [folder accessed] I then post it like; Code: [Select] <? $fn = "xxxxxxxxxx.log"; print htmlspecialchars(implode("",file($fn))); ?> That works fine but what i want to be able to do is read/edit the text files, so the main things i need to add is; The ability to clear the log (using password for confirmation) not sure how to go about this because i don't know how to edit the text file <input name="password" type="text"> <input type="submit" value="Clear Log?"> I also need a script to read the log and alert me an ip address that isn't mine is found, maybe something like if (an ip that isn't mine == yes) echo "an unknown ip accessed something" Also lets say i have a script that checks if a name exists, how can i use a text file containing a list of names to be read by a script if (name exists in text file) echo "name exists" else echo "name doesn't exist" All these questions are similar in the fact i need to understand how to open and read text files for specific entries, hope you understand, thanks for any help. Hey guys, im new hear so im not shore how things work. Iv got a project where we are ment to alow users to record a bug fault in a computer, currently i have a page that looks like ths: <?php if (empty($_POST['bug_ID'])) echo "<p>You must enter a BUG ID number</p>"; else { $bugID = addslashes($_POST['bug_ID']); $name = addslashes($_POST['bug_name']); umask(0007); if (!file_exists("../../data/lab05")) mkdir("../../data/lab05", 02777); $lab05 = fopen("../../data/lab05/". "$bugID.txt", "a"); if (is_writable("../../data/lab05/NewBug.txt")) { if (fwrite($lab05, $bugID . ", " . $name . "\n")) echo "<p>Thank you entering a new bug</p>"; else echo "<p>Cannot add bug</p>"; } else echo "<p>Cannot write to the file.</p>"; fclose($lab05); } ?> this code runs fine however I also need to write a sperate page that allows for users to search and up date bugs recorded, I want them to search using the bug_ID field and we are ment to use the fgets method but am unshore, anyhelp would be much apricated. thank you I'm importing some text files from my windows servers in to a SQL database, but I'm running in to what I think is some sort of issue with either a special character or something to do with UTF-8, or UTF-16... I haven't dealt with this before, so I'm really not even sure. I read in the file as such: $handler = fopen($file, "r"); $Data = fread($handler, filesize($file)); fclose($handler); The text file itself contains the data formatted like this: Quote Unable to deliver this message because the follow error was encountered: "This message is a delivery status notification that cannot be delivered.". The specific error code was 0xC00402C7. The message sender was <>. The message was intended for the following recipients. OnlineHelp@somedomain.com If I simply echo out this data: echo $Data It'll come out in Firefox like the following. And I can see FF is choosing to view it as Western (ISO-8859-1), but if I choose to use Unicode (UTF-16) then the data displays correctly.

I only want the text file to have the last fifty lines (\n) delimited So, how do I make it delete the excess from the TOP of the file? So if it had 60 lines, I would want it to only have lines 10-60 to net 50 total. Thanks. ok I have a text file that has ids listed each on a new line how can I go about assigning each id to a variable so like 12312412 23432443 34654366 56456345 the variable $ids = all of the ids above one at a time in an array so like $ids[] = 12312412; $ids[] = 23432443; $ids[] = 34654366; $ids[] = 56456345; How would I open a text file from another server and echo it. http://mysite.com/news/feed.txt Hello, I had simple php website in one folder, no database in the website. I need a method for text search in the web directory... Any help? Thanks Hello everyone, This is my first post and I need a little help. My knowledge of php is limited, so this question may look simple. English isn't my mother tongue, which you have probably noticed already. So, my problem: I 've made a a phpscript that adds text to a txt-file, that works perfect, but I also need something to delete some parts of the file. part of my html-code: Code: [Select] <form method="POST" action="verwijderscript.php"> <table class="noborder"> <tr><td class="noborder"> <input type="text" id="verwijdertitel" name="verwijdertitel" size="40"> <input type="submit" name="s1" value="Verwijder Bericht" /> </td></tr> </table> </form> part of my txt-file: Code: [Select] <div id="Testtitel"> <span class="subtitel">Testtitel</span> <span class="rechts">Gepost op 15/03/2011</span> <br> <img class="nieuws" src="image.gif"><br> texttexttexttexttext<br> texttexttext<br> text <div class="streep"></div> </div id="Testtitel"> <div id="Testtitel2"> <span class="subtitel">Testtitel2</span> <span class="rechts">Gepost op 15/03/2011</span> <br> <img class="nieuws" src="image2.gif"><br> texttexttexttexttext<br> texttexttext<br> text <div class="streep"></div> </div id="Testtitel2"> part of my php-code: Code: [Select] <?php $titel = $_POST['verwijdertitel']; $oud = file_get_contents("data.txt"); $data = fopen("data.txt", "w+"); $nieuw = str_replace("id=\""$titel, "id=\"hidden", $oud); fwrite($data, "$nieuw"); fclose($data); header("refresh:0;url=http://www.test.com"); ?> css: Code: [Select] #hidden{display:none;} Problem: parse error line 6 of php-file And I don't think this works if the error is solved. I don't have a MySQL database, that's why I use a txt files. What I try to do is to hide the div, it would be better to delete it, but than I need to work with regex, I guess I am trying to add a txt file to a mysql database. Is there any one that can help? Here are the details TEST.TXT contains the following A001200910019999999900000200000000000000000000000 00000000000000000000000000 A002200910019999999900000610000000000000000000000 00000000000000000000000000 A003200910019999999900000687500000000000000000000 00000000000000000000000000 A004200910019999999900000335000000000000000000000 00000000000000000000000000 A005200910019999999900000626500000000000000000000 00000000000000000000000000 A006200704019999999900000423500000000000000000000 00000000000000000000000000 A007200910019999999900000323500000000000000000000 00000000000000000000000000 A008200704019999999900000102500000000000000000000 00000000000000000000000000 And so on up to 200 rows long I need to split each row the same way and add them to a table I will use the first row as an example Character 1 to 4 (A001) entered into a field called name Character 5 to 12 (20091001) entered into a field called efdate Character 13 to 20 (99999999) entered into a field called exdate Character 21 to 31 (00000200000) entered into a field called prfee Character 32 to 42 (00000000000) entered into a field called assfee Character 43 to 53(00000000000) entered into a field called spfee Character 54 to 64 (00000000000) entered into a field called anfee Character 65 to 75 (00000000000) entered into a field called nanfee Thanks in advance for the help Hey, Currently i have a chat room which calls my database quite frequently... so im thinking i can lower the heavy load from my server by taking it off MYSQL methods and using PHP read/write/delete methods of a text file. Now i have two issues with this... first one is: Code: [Select] <?php $myFile = "chatlist.txt"; $fh = fopen($myFile, 'w') or die("can't open file"); $stringData = $Message.'<br/>'; fwrite($fh, $stringData); fclose($fh); ?> This writes the most recent line, how ever the next line that gets sent overwrites so theres only ever one line in the txt file =/ Secondly how on earth do you delete a specific line from the file efficiently ? Say for example a line which broke the rules some how like spam was posted etc. Hope you get shed light on this. Thanks $tracking_file_location = "../dispatch-manager/logs/tracking_file.txt";
$tracking_file = fopen("$tracking_file_location", "r") or die("Unable to open file!");
$tracking_file_size = filesize("$tracking_file_location");
$tracking_file_text = fread($tracking_file,$tracking_file_size);
fclose($tracking_file);
