PHP - Shorten Text File
Ok, I have a log file that is written to. 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. Similar Tutorials
The $a variable contains the news text. The $link variable contains a link to the page with the full text of this news. change text Hi, When a user POSTS 10 maps (dropdown), I don't want any two or more being the same. From my knowledge, only way I know of doing this, is this very long messy way: Code: [Select] if($_POST['map1']==$_POST['map2'] || $_POST['map1']==$_POST['map3'] || $_POST['map1']==$_POST['map4'] || $_POST['map1']==$_POST['map5']) etc... then I need to type if $_POST['map2']==$_POST['map1'] etc... How can I put this in its simplest form so that there are no POST duplicates? Thanks for any help. Hi everyone, I know im being really picky here, but im trying to optimize my code, and i was wondering if there is any way i can shorten the following: if ($submit) {echo $name;} else {echo $row['dbname'];} I know it fairly short already however im using it as the value of a html text box. Thanks I need help to shorten the following url in apache .htaccess

Hey all, I really like programming in PHP, but I'm still in the learning process. And mostly, I'm not that good in making my code short. This is now the case again. I have this code which gets a lot of checkboxes, only checkboxes, out of a mysql database, for a planning project. Now the code I have so far, retrieves the checkboxes, which are booleans in the database, and checks if they are True or False and sets the checkboxes respectively to checked="yes" or not. This code works. But I'm here to get tips on how to shorten my code, since it's very repetitive and thus long, which isn't quite efficient. As I said, I'm still in learning process, so I hope you guys understand that I'm looking for help with this. Thanks. EDIT: Okay, I now suddenly see, that I can use elsif for True and False. This would be logical to do, and I can accomplish this easily. But it would be still very repetitive. Here's the code: Code: (php) [Select] <?php while ($row = mysql_fetch_array($result)){ // UNCHECKED if ($row['fact-sent'] == false){ $fact_sent = '<input type="checkbox" />'; } if ($row['fact-payed'] == false){ $fact_payed = '<input type="checkbox" />'; } if ($row['domain'] == false){ $domain = '<input type="checkbox" />'; } if ($row['content'] == false){ $content = '<input type="checkbox" />'; } if ($row['design-sent'] == false){ $design_sent = '<input type="checkbox" />'; } if ($row['design-approved'] == false){ $design_approved = '<input type="checkbox" />'; } if ($row['design-sliced'] == false){ $design_sliced = '<input type="checkbox" />'; } if ($row['temp-website'] == false){ $temp_website = '<input type="checkbox" />'; } if ($row['temp-website-sent'] == false){ $temp_website_sent = '<input type="checkbox" />'; } if ($row['temp-website-approved'] == false){ $temp_website_approved = '<input type="checkbox" />'; } if ($row['cms'] == false){ $cms = '<input type="checkbox" />'; } if ($row['seo'] == false){ $seo = '<input type="checkbox" />'; } if ($row['analytics'] == false){ $analytics = '<input type="checkbox" />'; } if ($row['webmaster-tools'] == false){ $webmaster_tools = '<input type="checkbox" />'; } if ($row['website'] == false){ $website = '<input type="checkbox" />'; } if ($row['website-online'] == false){ $website_online = '<input type="checkbox" />'; } // CHECKED if ($row['fact-sent'] == true){ $fact_sent = '<input type="checkbox" checked="yes" />'; } if ($row['fact-payed'] == true){ $fact_payed = '<input type="checkbox" checked="yes" />'; } if ($row['domain'] == true){ $domain = '<input type="checkbox" checked="yes" />'; } if ($row['content'] == true){ $content = '<input type="checkbox" checked="yes" />'; } if ($row['design-sent'] == true){ $design_sent = '<input type="checkbox" checked="yes" />'; } if ($row['design-approved'] == true){ $design_approved = '<input type="checkbox" checked="yes" />'; } if ($row['design-sliced'] == true){ $design_sliced = '<input type="checkbox" checked="yes" />'; } if ($row['temp-website'] == true){ $temp_website = '<input type="checkbox" checked="yes" />'; } if ($row['temp-website-sent'] == true){ $temp_website_sent = '<input type="checkbox" checked="yes" />'; } if ($row['temp-website-approved'] == true){ $temp_website_approved = '<input type="checkbox" checked="yes" />'; } if ($row['cms'] == true){ $cms = '<input type="checkbox" checked="yes" />'; } if ($row['seo'] == true){ $seo = '<input type="checkbox" checked="yes" />'; } if ($row['analytics'] == true){ $analytics = '<input type="checkbox" checked="yes" />'; } if ($row['webmaster-tools'] == true){ $webmaster_tools = '<input type="checkbox" checked="yes" />'; } if ($row['website'] == true){ $website = '<input type="checkbox" checked="yes" />'; } if ($row['website-online'] == true){ $website_online = '<input type="checkbox" checked="yes" />'; } // OUTPUT echo '<tr><td class="customer">'.$row['project'].'</td><td class="customer">'.$row['customer'].'</td><td class="data">'.$fact_sent.'</td><td class="data">'.$fact_payed.'</td><td class="data">'.$domain.'</td><td class="data">'.$content.'</td><td class="data">'.$design_sent.'</td><td class="data">'.$design_approved.'</td><td class="data">'.$design_sliced.'</td><td class="data">'.$temp_website.'</td><td class="data">'.$temp_website_sent.'</td><td class="data">'.$temp_website_approved.'</td><td class="data">'.$cms.'</td><td class="data">'.$seo.'</td><td class="data">'.$analytics.'</td><td class="data">'.$webmaster_tools.'</td><td class="data">'.$website.'</td><td class="data">'.$website_online.'</td></tr>'; } ?> hello, is it possible to get the 1274 out of the following?

Hello everyone For a site of one of our customers our programmer created his own CMS which works OK at the site, but now the customer wants to shorten the URLS which are generated by the system. Is this easily possible? The programmer doesn't have the time to help us with it so that's why I try my luck here... I hope somebody can help me. Thanks! 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. Hi, 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 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 Hello, i am currently getting an Microsoft Excel formatted text file whose save type is .Txt from a URL.I used to open it and will change the save type as excel file.

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.

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 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 How would I open a text file from another server and echo it. http://mysite.com/news/feed.txt I am trying to add a txt file to a mysql database. Is there any one that can help?
