I've tryed some ways to automatically unzip files with php but all of them failed:
1st variant
<?php
function unzip($file){
$zip=zip_open(realpath(".")."/".$file);
if(!$zip) {return("Unable to proccess file '{$file}'");}
$e='';
while($zip_entry=zip_read($zip)) {
$zdir=dirname(zip_entry_name($zip_entry));
$zname=zip_entry_name($zip_entry);
if(!zip_entry_open($zip,$zip_entry,"r")) {$e.="Unable to proccess file '{$zname}'"; continue; }
if(!is_dir($zdir)) mkdirr($zdir,0777);
#print "{$zdir} | {$zname} \n";
$zip_fs=zip_entry_filesize($zip_entry);
if(empty($zip_fs)) continue;
$zz=zip_entry_read($zip_entry,$zip_fs);
$z=fopen($zname,"w");
fwrite($z,$zz);
fclose($z);
zip_entry_close($zip_entry);
}
zip_close($zip);
return $e;
}
$file = 'file_name.zip';
echo unzip($file);
2nd variant
<?php
$zip = zip_open("my_linkedin_groups_scrape_my_run_1_2015.zip");
if ($zip) {
while ($zip_entry = zip_read($zip)) {
$fp = fopen("./".zip_entry_name($zip_entry), "w");
if (zip_entry_open($zip, $zip_entry, "r")) {
$buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
fwrite($fp,"$buf");
zip_entry_close($zip_entry);
fclose($fp);
}
}
zip_close($zip);
}
?>
3rd variant
<?php
// assuming file.zip is in the same directory as the executing script.
$file = 'file.zip';
// get the absolute path to $file
$path = pathinfo(realpath($file), PATHINFO_DIRNAME);
$zip = new ZipArchive;
$res = $zip->open($file);
if ($res === TRUE) {
// extract it to the path we determined above
$zip->extractTo($path);
$zip->close();
echo "WOOT! $file extracted to $path";
} else {
echo "Doh! I couldn't open $file";
}
?>
for the 3rd case output is Doh! I couldn't open file.zip
What's wrong? Am I something missing?
I
Seems like a problem with write/read rights.
Change the rights for testing purposes on to 0777
I would go with 3rd variant. Try using absolute path to zip file and dump $res in the error message. It will say exactly whats wrong, just compare it with specific error codes http://php.net/manual/en/ziparchive.open.php.

I'm beginner in html and php. I trying to create a script that will open the directory, display all text files, open each of them for editing and save the changes to a file (all the script operation will be transferred to the html form). Unfortunately, after opening the directory and viewing the files, I have trouble reading their contents. Could someone tell me what I doing wrong ?
Thank for help
<?php
$path = "books/";
$books = opendir($path);
while (($book = readdir($books)) !== false)
{
echo $book;
foreach (glob("*.txt") as $readfile)
{
$readFile = fopen($book, "r") or die("Permission error");
echo fread($readFile, filesize($book));
fclose($readFile);
}
}
closedir();
?>
Server response:
...Atlas_chmur.txtDiuna.txt
I used the loop so that only .txt files were opened. Currently I have this:
<?php
$path = "books/";
$books = opendir($path);
while (($book = readdir($books)) !== false)
{
echo $book;
$readFile = fopen($book, "r") or die("Permission error");
echo fread($readFile, filesize($book));
fclose($readFile);
}
closedir();
?>
Now I'm getting an error when trying to read the files.
Server response:
. Warning: fopen (.): Failed to open stream: Permission denied in C: \ xampp \ htdocs \ BooksEditorForm \ index.php on line 9 Permission error
Try this code
$path = "blog/";
$books = opendir($path);
while (($book = readdir($books)) !== false)
{
if( substr($book, -4) === ".txt" )
{
$filePath = $path.$book;
$readFile = fopen($filePath, "r") or die("Permission error");
echo fread($readFile, filesize($filePath));
fclose($readFile);
}
}
closedir();
Let me explain it...
First, occasions where you need loop inside a loop are quite rare so if your code has them, analyze it because there's a big possibility that problem can be solved differently and more efficient.
Code: value of $book is string that contains filename so simple use of substr() function to check last 4 characters will tell us is it of "*.txt" format.
Other thing that is changed is filepath; $book contains it's name but your script is looking for a file from its own perspective so file path should be containing folder + filename.
And there's no need for closing PHP tags at the end unless you have something else following it that is not PHP (like HTML).
I have used the below code. It's working well.try this code
$files = scandir('books/');
if(count($files) > 0) {
foreach ($files as $key => $value) {
echo '<pre>'; print_r($value); echo '</pre>';
// to read files data
$readFileVar = fopen ($value, "r");
while ($filedata = fgets($readFileVar)) {
print_r($filedata);
}
}
}
I'm running 2 simple function:
<?php
$zipUrl = "path_of_original.zip"
$zipFilename = "local_path_and_name_of.zip"
$unzipPath = "destination_of_unzipped_files"
upload_archive ($zipUrl, $zipFilename);
unzip_archive ($zipFilename, $unzipPath);
?>
the 1st, upload a .zip archive on server
function upload_archive ($zipUrl, $zipFilename){
define('BUFSIZ', 4095);
$rfile = fopen($zipUrl, 'r');
$lfile = fopen($zipFilename, 'w');
while(!feof($rfile))
fwrite($lfile, fread($rfile, BUFSIZ), BUFSIZ);
fclose($rfile);
fclose($lfile);}
the 2nd, unzip the archive
function unzip_archive ($zipFilename, $unzipPath){
$zip = new ZipArchive;
$res = $zip->open($zipFilename);
if ($res === TRUE) {
$zip->extractTo($unzipPath);
$zip->close();
echo 'success!';
} else {
echo 'error!';
}
}
when these 2 functions are executed separately everything's fine, but when executed in sequence I can't appreciate the output of the second function (unzip).
I think the problem is that the .zip file is still locked in write by the first function.
any Suggestions?

I have a textfile ($file) that contains the path to other files. My goal is to read the content of those files and print it in a table. When reading the paths from $file, only the last line path works correctly.
<?php
$file = "log2.txt";
if(file_exists($file)) {
$handler = fopen($file,'r');
while(!feof($handler)) {
$lines = fgets($handler);
$wordarray = explode(' ', $lines);
#echo $wordarray[0]." ".$wordarray[1]." ".$wordarray[2];
if (strpos($lines, 'NOK') !== false) {
echo "<tr><td>".$wordarray[0]."</td></tr>";
if(file_exists($wordarray[2])){
$log = fopen($wordarray[2], 'r');
#echo "FILE EXISTS ".$log;
$logtext = fread($log,filesize($wordarray[2]));
echo "<tr><td>".$logtext."</td></tr>";
fclose($log);
} else {
echo "<tr><td>"."FILE ".$wordarray[2]." FAILED TO LOAD"."</td></tr>";
}
}
}
fclose($handler);
} else {
echo "FILE DOES NOT EXISTS";
}
?>
Here is an exemple of how log2.txt would look like:
POE NOK poelog.txt
LINK-ERRORS OK OK
LATENCIES NOK latencieslog.txt
VOLATILE NOK volatilelog.txt
I think that the problem could be about line endings or so, but cannot get the point.
You're right. The $wordarray[2] contains also new line character so before using it pass it through trim() function and store it in a variable ($filename in my case).
Updated inner if:
if (strpos($lines, 'NOK') !== false) {
echo "<tr><td>".$wordarray[0]."</td></tr>";
$filename = trim($wordarray[2]);
if (file_exists($filename)){
echo "FILE EXISTS ".$filename;
$log = fopen($filename, 'r');
$logtext = fread($log, filesize($filename));
echo "<tr><td>".$logtext."</td></tr>";
fclose($log);
}
else{
echo "<tr><td>"."FILE ".$filename." FAILED TO LOAD"."</td></tr>";
}
}
This short function works like a sharm:
function displayFileContent( $fileName )
{
$arrayWithFileNames = file ( $fileName );
echo "<table>";
foreach ( $arrayWithFileNames as $singleFileName )
{
# remove the trailing \n on Linux - windows has 2 character as EOL
$singleFileName = trim(preg_replace('/\s\s+/', ' ', $singleFileName));
$contentOfFile = file_get_contents( $singleFileName );
echo "<tr><td>{$contentOfFile}</td></tr>";
}
echo "</table>";
}
You use it like this:
displayFileContent ("path-to-your-file");
Remark: There is no check if the file does exist....
Okay. Every file exists, is readable, and is writable. ZIP produces no errors, and outputs: "numfiles: 140 status:0".
the code reads a log, checks for specific text, then imports a number of images into a zip folder. everything runs great except the zip folder is always empty. I've read a lot of threads about this, and they all were resolved by changing permissions, modifying paths and checking for read/write/exist/errors. but... nothing has worked. whats up?
<?php
$file = fopen("log.log", "r") or exit("Unable to open file!");
$zip = new ZipArchive();
$filename = "E:/Web Sites/whatever/order_stream/images.zip";
$try_file = $zip->open($filename,ZIPARCHIVE::OVERWRITE);
if ($try_file !== true) {
exit("cannot open <$filename>\n");
}
while(!feof($file)) {
$line = fgets($file);
$results = explode(": ", $line);
if ($results[0] == "Copying" || $results[0] == "File already exists, overwriting") {
$file_name = substr($results[1],19);
$to_zip = "E:/Web Sites/whatever/catalog/pictures/".$file_name;
$to_zip = trim($to_zip);
if (file_exists($to_zip)) {
$zip->addFile($to_zip);
}
}
}
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
fclose($file);
?>
The ZipArchive::addFile() method accepts the path to the file as its first parameter, but not all paths are created equal. addFile() method silently rejects (bug?) the file and you never know what went wrong. An alternative approach would be:
// $zip->addFile($file);
$content = file_get_contents($file);
$zip->addFromString(pathinfo ( $file, PATHINFO_BASENAME), $content);
In addition to getting the code working, file_get_contents() also generates decent error messages if you made an error in the path. In this example
$file = $full_directory_path_ending_with_slash.$filename;
Since in the above question, you have the parts in your fingers, the code could simply become:
$content = file_get_contents($to_zip);
$zip->addFromString($filename, $content);
I have a list of file paths that I want to delete. I placed the file paths in a plaintext file in the root directory of the server. For example:
files_to_be_removed.txt
/path/to/bad/file.php
/path/to/another/bad/file.php
In the same directory, I have another file:
remove.php
$handle = #fopen("files_to_be_removed.txt", "r");
if ($handle) {
while (($buffer = fgets($handle, 4096)) !== false) {
if (unlink($buffer))
echo $buffer . ' removed.';
}
fclose($handle);
}
When I run my script, nothing is output. Simply, the files in the list aren’t being deleted. Why is that?
$files = file('files_to_be_removed.txt', FILE_IGNORE_NEW_LINES);
foreach ($files as $file) {
if (#unlink($file)) {
echo $file, ' removed', PHP_EOL;
} else {
$error = error_get_last();
echo 'Couldn\'t remove ', $file, ': ', $error['message'], PHP_EOL;
}
}
I'm guessing files are not being deleted because "you already have a LOCK on it" [just a guess] -- since you open it and check it's content.
You can avoid all the stress and simply adjust your entire script to a few lines:
foreach($filepaths as $filepath){
$status = #unlink($filepath);
#the # is there for error suppression -- in case the file doesn't exist
if($status){
#do what you want -- it was successful
}
}
