PHP - Fopen + Fgets + File Sizes ???
I have a script that I am trying to transfer one file from a remote server to my local server and save it. The files can be quite large. I have successfully backed up around 200 MB... But, anything over that seems to fail with a strange error... I was hoping for a little guidance... here is my code and error/warning that I get:
PHP Code: function remote_capture($tmp_url, $filename) { $r_handle = fopen($tmp_url, "rb"); $d_handle = fopen($filename, 'w'); if($r_handle&&$d_handle) { while(($buffer = fgets($r_handle)) !== false) { fputs($d_handle, $buffer); } fclose($r_handle); fclose($d_handle); return true; } else { return false; } } Warning Message: Warning: file_get_contents(URL_OF_MY_SCRIPT_HAS_BEEN_REMOTED) [function.file-get-contents]: failed to open stream: HTTP request failed! in /path/on/my/local/server/to/script on line 298 Similar Tutorialshi, I want to write pdf file but it is getting garbage value i check following url http://bugs.php.net/bug.php?id=21904&edit=1 Code: [Select] $fp = fopen($fdirandname,'wb'); fwrite($fp,$pdfcode); fclose($fp); Hiya, Firstly, I'm a complete novice, apologies! But I have got my upload.php working which is nice. I will post the code below. However, I would now like to restrict the file size and file type to only word documents. I currently have a restriction of 200KB but it's not working - no idea why as I've looked at other similar codes and they look the same. Also, just to complicate things - can I stop files overwriting each other when uploaded? At the moment, if 2 people upload files with the same name one will overwrite the other. Is this too many questions in 1? Any help is very much appreciated! Code below: Code: [Select] <form enctype="multipart/form-data" action="careers.php" method="POST"> Please choose a file: <input name="uploaded" type="file" /><br /> <input type="submit" value="Upload" /> </form> <?php $target = "upload/"; $target = $target . basename( $_FILES['uploaded']['name']) ; $ok=1; //This is our size condition if ($uploaded_size > 200) { echo "Your file is too large.<br>"; $ok=0; } //This is our limit file type condition if ($uploaded_type =="text/php") { echo "No PHP files<br>"; $ok=0; } //Here we check that $ok was not set to 0 by an error if ($ok==0) { Echo "Sorry your file was not uploaded"; } //If everything is ok we try to upload it else { if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) { echo "Your file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded."; } else { echo "Sorry, there was a problem uploading your file."; } } ?> So in my last thread I was working on checking if a file was there...I resorted to something not in the library and used $pic_exists_jpg = fopen($jpg_path,'r'); $pic_exists_jpeg = fopen($jpeg_path,'r'); $pic_exists_gif = fopen($gif_path,'r'); $pic_exists_png = fopen($png_path,'r'); if ($pic_exists_jpg != '0') { $jpg_test = '1'; } elseif ($pic_exists_jpg == '1') { $jpg_test = '2'; } elseif ($pic_exists_jpg == '0') { $jpg_test = '2'; } elseif ($pic_exists_jpeg != '0') { $jpeg_test = '1'; } elseif ($pic_exists_gif != '0') { $gif_test = '1'; } elseif ($pic_exists_png != '0') { $png_test = '1'; } now for some reason php is being a poo and no matter what returning that there is a file there. no matter what method i use be it fopen or file_exists or anything else, it saying I have a file in that directory BUT I DO NOT! THERE IS NOT ONE OF THOSE FILES. I know I have my paths right because If I echo them directly I get the picture...what the heck?! if (!file_exists('../images/flags/imNum.txt')) { $file1 = fopen('../images/flags/imNum.txt','c'); fclose($file1); } why won't that work =\ it makes no sense to me Hey guys, I have a script that is run once a week to fetch some user info for a large number of accounts. The code I have now writes the info correctly, but I was wondering if there was an easy way to have the accountdata.txt file completely wiped before new updated info is written to it, as opposed to deleting it manually every week. $FileName = "accountdata.txt"; $f=fopen($FileName,"a+"); fwrite($f, $UserKey[$i]." ".$SigKey[$i]."\n"); $f=fclose; I could in theory just open the file and delete everything in it manually, save it and then run this script, but I'm always looking for more ways to make things efficient, and come a time when it's run more than once a week it'd be nice to have all that automated. So in summary, I need it to delete all data (if any) from the accountdata.txt file before it writes anything to it. Thanks. Can't figure out why the page wont save after clicking save. $KOHDE="index.php?s=admin"; $LOMAKE_W = 400; $TEXTAREA_W = 50; $TEXTAREA_H = 20; $LOMAKE = mysql_real_escape_string($_GET["l"]); $LOMAKE2 = mysql_real_escape_string($_POST["lomake"]); after a few more lines... elseif ($LOMAKE2 == "etusivu"){ #Etusivun muokkaus $teksti = stripslashes($_POST["teksti"]); $f = fopen("etusivu.php", "w"); fwrite($f, $teksti); fclose($f); } elseif ($LOMAKE == "etusivu"){ #Etusivun muokkaus echo "<h1>Edit home page</h1>"; $f = file("etusivu.php"); echo "<form action='$KOHDE' method='post'> <textarea name='teksti' cols='$TEXTAREA_W' rows='$TEXTAREA_H'>"; for ($i = 0; $i < count($f); $i++){ $f[$i] = str_replace("\"", "''", $f[$i]); echo $f[$i]; } echo "</textarea> <input type='hidden' value='etusivu' name='lomake'/> <br><input type='submit' value='Save'/> </form><br/>"; html_ohje(); } I can't see where it has gone wrong. Can anyone help? Hey, I'm trying to open a .php file and read a comment block that is in the beginning of the file. I'm having some trouble in that nothing is being echoed out. Here is the reading file: <?php $fb = fopen("tepl.php", "r"); $data = fread($fb, 8192); fclose($fb); var_dump($data); ?> here is the file (tepl.php) being read: <?php /* Name: Test Plugin 1 URI: http://www.theorangeday.com/plugintest/ Description: This is just a test plugin because I need to test how this thing is going to work overall. Author: Thomas Francis Author URI: http://www.theorangeday.com/ Version: 0.1 */ function test_plugin(){ echo "we loaded the test plug"; } ?> the var_dump returns Code: [Select] string(321) " " What's wrong here? Hello, I'm working on a script which should read lines from a file keyword.txt create a new file with that variable name, insert the content close and loop through all the lines in the keyword file. The loop itself works but now that i'm adding the fopen fwrite and fclose i'm running into trouble. I'm not that great a coder and have pieced this together so far. I'd appreciate any suggestions on how to fix the fopen and other file functions to create unique files using the keywords from the file Thanks in advance <?php $read_file = file('keywords.txt'); foreach($read_file as $var) { $file = fopen($var, "x"); $content = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"> <html xmlns=\"http://www.w3.org/1999/xhtml\"> <head> <meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /> <title>This is the title</title> </head> <body> <h2>The keyword is $var</h2> <p><p> </body> </html>"; fwrite($file, $content); fclose($file); } ?> I have a php script on a server writing to an html file on a remote server. I'm using the following combination of fopen and fputs. The problem is that once out of maybe every 10 or 15 writes to the file, the file that is written is blank with nothing in it. Has anyone here had experience with this before? The file is fixed the next time it writes to it. this code is within a loop that runs every 10 seconds. Code: [Select] // Allows overwriting of existing files on the remote FTP server $stream_options = array('ftp' => array('overwrite' => true)); // Creates a stream context resource with the defined options $stream_context = stream_context_create($stream_options); // Opens the file for writing and truncates it to zero length if ($fh = fopen($ftp_path, 'w',0, $stream_context)) { if ( $change > 0 ) fputs($fh, "the contents of the html file is here"); //the case if change is positive else fputs($fh, "the contents of the html file is here"); //the case if change is negative // Closes the file handle fclose($fh); } else { die('Could not open file.'); } By using fgets i want to print what's located in the file with comma's however in the end there shouldn't be any comma I have this code so far: $file = fopen("file.txt", "r"); while(!feof($file)) { echo "<a href=" . fgets($file). ">" . fgets($file) . "</a><br />"; } fclose($file); but if i use fgets twice (like above) it makes the link, link to the previous result I've been doing some limited PHP coding for a while, but never really had any training, just learned by searching for specific needs. So I decided to get a book and start from the beginning to see what else PHP can do that I don't know about. Problem is that I can't even get past the first simple program in the book. I'm just supposed to take input from the user and save it to a variable with this line of code: Code: [Select] $name = fgets(STDIN); But when I access that page on my webserver, I get this error: Warning: fgets() expects parameter 1 to be resource, string given in /Users/username/Sites/sitename/index.php There's got to be something simple I'm missing, since this is the easiest task in the book. Any help is appreciated. Thanks! I run a dev site locally on Windows and the real site on a hosting provider on LINUX. PHP5, XAMP, etc. Locally my fopen works. On the web server it throws an error: "Warning: fopen() [function.fopen]: Unable to access" filepath/name The file exists on both servers; upper/lower case is correct; so are access rights. I noticed the error only today; this was working for the last 7 months; the function serves a range of content-types; just tested XLS and it works. Now I am stuck This line throws the error: $handle = fopen($strPathFileName, 'rb'); $strPathFileName uses / only Any pointers appreciated... thanks. Hi guys, I'm doing a website for the condo and I'm having troubles with the new year party registration form. I think it's got something to do with my file handling.

Hey all, my doubt is the following: Is there a way of opening files (images,pdf's,etc) in a popup window? What I intend to do, is have a button, that when pressed, would acess and open certain files in a popup window. I already know how to acess and download the files, but I would like to know how to open them inside the browser. sorry for the bad English. Hope you understood and can help. Thanks alot, Ruben I'm having trouble connecting through fopen using variables as the login details, but with file_get_content it works fine?! These are my variables:- $ftpaddy="ftp.mydomain.com"; $username="me"; $password="password"; $editingdir="/public_html/edit/"; $editfile="editme.txt"; $myftppath = "ftp://" . $username . ":" . $password . "@" . $ftpaddy . $editingdir . $editfile; //puts all variables into string When I try to connect and read the file using the following method it works fine:- $file = file_get_contents("$myftppath", "r"); but when i try and use the same string with fopen as below it doesn't work?! the line i have commented out however works and when i echo the $myftppath variable below it looks the same.. i don't really get it! //$myftppath = "ftp://me:password@ftp.mydomain.com/public_html/edit/editme.txt"; $myftppath = "ftp://" . $username . ":" . $password . "@" . $ftpaddy . $editingdir . $editfile; //puts all variables into string $stream_options = array('ftp' => array('overwrite' => true)); $stream_context = stream_context_create($stream_options); if ($fh = fopen($myftppath, 'w', 0, $stream_context)){//fopen only likes the commented out $myftppath not the one using the variables?! fputs($fh, $newcontents); fclose($fh); } else { die('Could not open file.'); } does anyone know if I am doing the syntax wrong and how to correct it? I read I may need to put another slash after domain.com but this didn't help either. any help would be much appreciated! thanks in advance Kev. Hey all i am attempting to connect to a ftp address and display the contents of a file into a textarea and i keep getting errors is there something wrong with the code or the ftp server? <?php $log_file= "ftp://username:password@68.232.164.100/czero/68.232.164.100:27015/czero/gsconsole.log"; $log_handle = fopen($log_file, "r"); $log_contents = fread($log_handle, filesize($log_file)); fclose($log_handle); ?> Console Log: <textarea name="log_view" cols="110" rows="20" readonly="readonly" wrap="virtual"><?php echo "$log_contents" ; ?></textarea> Hi, I am modding phpBB3 and I want to make the contents of a text documents appear in a border.

Thanks. I have this function to get other website title tag. But since the fopen is disabled in my shared server, this function cannot work. How can i still do it? thanks in adv function getTitle($Url){ $file=@fopen($Url,"r"); if($file) { fclose($file); $str=file_get_contents($Url); if($str) { if(strlen($str)>0){ preg_match("/\<title\>(.*)\<\/title\>/",$str,$title); return $title[1]; } }else{ return true; } }else{ return false; } } |
