I'm trying to move folder to other folder, with all it's files. Both folders are in root directory. Tried a lot of ways, and always get no result.
Here is my latest atempt:
$source = "template/"
$dest = "projects/"
function copyr($source, $dest){
if (is_link($source)) {
return symlink(readlink($source), $dest);
}
if (is_file($source)) {
return copy($source, $dest);
}
if (!is_dir($dest)) {
mkdir($dest);
}
$dir = dir($source);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
copyr("$source/$entry", "$dest/$entry");
}
$dir->close();
return true;
}
Need professional glance to tell me, where I'm getting it wrong?
EDIT:
Sorry for wrong tags.
Problem is - nothing is happening. Nothing is being copied. No error messages. Simply nothing happens.
File structure:
I suggest to try and do the following
How do you run the scrips? Do you open page in browser or run script in command line? If you open page in browser this might be an issue with permissions, paths (relative and not absolute) and errors not shown but logged.
Use absolute folder paths instead of relative paths. For example /var/www/project/template.
Apply realpath() function to all paths and check (output) the result. If path is wrong (folder does not exist, separators are wrong etc) you will get empty result from the function.
Make sure to use DIRECTORY_SEPARATOR instead of / if you run your script on Windows. I can not check if / works on Windows now but potentially this might be an issue. For example
copyr($source.DIRECTORY_SEPARATOR.$entry", $dest.DIRECTORY_SEPARATOR.$entry);
Check warnings and errors. If you do not have permission you should get warning like this
PHP Warning: mkdir(): Permission denied
You may need to enable warnings and errors if they are disabled. Try for example to make an obvious mistake with name and check if you get any error message.
Try to use tested solution from one of the answers. For example xcopy function.
Try to add debug messages or run your script in debugger step by step. Check what is happening, what is executed etc. You can add debug output near any operator like (just an idea):
echo 'Creating directory '.$name.' ... ';
mkdir($name);
echo (is_dir($name) ? 'created' : 'failed').PHP_EOL;
Hi there is there any way to check if .exe file exists on a given path or not.
I have installation of ImageMagic. I have a path of convert.exe of Image Magic. I need to check that in given path the convert.exe exists or not. I have implemented
$settingFileContent = file_get_contents($settingFilePath);
// print_r($settingFileContent);
$allPaths = unserialize(stripslashes($settingFileContent));
if (isset($allPaths['IMAGE_CONVERT_EXE'])) {
//cho $allPaths['IMAGE_CONVERT_EXE'];
if (file_exists($allPaths['IMAGE_CONVERT_EXE'])) {
$analysisResultObj->level = ENUM_SUCCESS;
} else {
$analysisResultObj->level = ENUM_ERROR;
$analysisResultObj->infoText = "Image Magic convert.ext has wrong path";
Logger::getLogger('Application')->error('Image Magic convert.ext has wrong path');
}
}
I can change the value of $allPaths['IMAGE_CONVERT_EXE'] in file. When I change to wrong value even in that condition it returns true.
Based on the documentation comment specifically about PHP on Windows I'm guessing (and let's be clear: everything in PHP is a guess) try this:
$file = 'd:/somfolder/imagemagic/convert.ext'
if(file_exists($file)) {
// should be false
}
Based on your actual code have you tried:
$file = $allPaths['IMAGE_CONVERT_EXE'];
if(file_exists($file)) {
// should be false
}
Looking at the documentation someone commented about having this same problem on Windows and being unable to return the correct result when concatenating string values. While you are not concatenating string values together its at least worth a shot to make sure there isn't something else strange going on.
To me it sounds like you're trying to get wether or not the Imagemagick extension exists. PHP provides ways for doing just that thus eliminating your extrapolated and insane approach all together.
<?php
echo extension_loaded('imagick');
?>
Additionally, you can get an idea of your installed extensions via
<?php
print_r(get_loaded_extensions());
?>
I like to do this:
if (file_exists( "path/a/b/c/file.txt" )) {
fopen("path/a/b/c/file.txt"); ----------> ERROR
do_this_if_file_exists();
}
else {
do_this_if_not_exists();
}
Unfortunately, I get the following error:
fopen(path/a/b/c/file.txt) [function.fopen]: failed to open stream: No such file or directory
What I'm doing wrong with file_exists?
In addition, when I call file exists with a path like: file_exists( "file.txt" ), that works well. I think the problem is the path (path/a/b/c/), but how to verify that without create the path first.
Thanks.
It is not a proper way to hide errors with #. All errors should be correctly handled. In other case debugging will be a pain.
Also, for the future you may use is_readable() function to make sure if the file is not only exists but also is readable, e.g. you have enough permissions.
You need to include error checking with fopen:
if (file_exists( "path/a/b/c/file.txt" ))
{
$fh=fopen("path/a/b/c/file.txt","r"); #or whatever mode you want...
if($fh!==false)
{
do_this_if_file_exists_and_can_be_opened();
}
else
{
die("Couldn't open the file. Sorry!\n");
}
}
else {
do_this_if_not_exists();
}
Check if given file exists and if it is realy a file:
if (file_exists( "path/a/b/c/file.txt" ) && is_file("path/a/b/c/file.txt")) {
$file_handler = #fopen("path/a/b/c/file.txt", MODE_IS_NOT_OPTIONAL)
if($file_handler !== false){
do_things_with_file_handler();
} else {
throw_some_error();
}
}
else {
do_this_if_not_exists();
}
Function file_exists() also can check if given directory exists and that shluod help You.
mode parameter in fopen function isn't optional as #Jack Maney pointed out. You have to use one of the mode possible values, full list.
Your problem is here:
fopen("path/a/b/c/file.txt");
Not only are you not assigning the return value to anything, but fopen() takes a required 2nd argument that you are not using.
You may turn off the error reporting by adding this line at the top of your php page
error_reporting(0);
I'm having a very weird issue with file_exists(). I'm using this function to check if 2 different files in the same folders do exist. I've double-checked, they BOTH do exist.
echo $relative . $url['path'] . '/' . $path['filename'] . '.jpg';
Result: ../../images/example/001-001.jpg
echo $relative . $url['path'] . '/' . $path['filename'] . '.' . $path['extension'];
Result: ../../images/example/001-001.PNG
Now let's use file_exists() on these:
var_dump(file_exists($relative . $url['path'] . '/' . $path['filename'] . '.jpg'));
Result: bool(false)
var_dump(file_exists($relative . $url['path'] . '/' . $path['filename'] . '.' . $path['extension']));
Result: bool(true)
I don't get it - both of these files do exist. I'm running Windows, so it's not related to a case-sensitive issue. Safe Mode is off.
What might be worth mentioning though is that the .png one is uploaded by a user via FTP, while the .jpg one is created using a script. But as far as I know, that shouldn't make a difference.
Any tips?
Thanks
file_exists() just doesn't work with HTTP addresses.
It only supports filesystem paths (and FTP, if you're using PHP5.)
Please note:
Works :
if (file_exists($_SERVER['DOCUMENT_ROOT']."/folder/test.txt")
echo "file exists";
Does not work:
if (file_exists("www.mysite.com/folder/test.txt")
echo "file exists";
Results of the file_exists() are cached, so try using clearstatcache(). If that not helped, recheck names - they might be similar, but not same.
I found that what works for me to check if a file exists (relative to the current php file it is being executed from) is this piece of code:
$filename = 'myfile.jpg';
$file_path_and_name = dirname(__FILE__) . DIRECTORY_SEPARATOR . "{$filename}";
if ( file_exists($file_path_and_name) ){
// file exists. Do some magic...
} else {
// file does not exists...
}
Just my $.02: I just had this problem and it was due to a space at the end of the file name. It's not always a path problem - although that is the first thing I check - always. I could cut and paste the file name into a shell window using the ls -l command and of course that locates the file because the command line will ignore the space where as file_exists does not. Very frustrating indeed and nearly impossible to locate were it not for StackOverflow.
HINT: When outputting debug statements enclose values with delimiters () or [] and that will show a space pretty clearly. And always remember to trim your input.
It's because of safe mode. You can turn it off or include the directory in safe_mode_include_dir. Or change file ownership / permissions for those files.
php.net: file_exists()
php.net: safe mode
Try using DIRECTORY_SEPARATOR instead of '/' as separator. Windows uses a different separator for file system paths (backslash) than Linux and Unix systems.
A very simple trick is here that worked for me.
When I write following line, than it returns false.
if(file_exists('/my-dreams-files/'.$_GET['article'].'.html'))
And when I write with removing URL starting slash, then it returns true.
if(file_exists('my-dreams-files/'.$_GET['article'].'.html'))
I have a new reason this happens - I am using PHP inside a Docker container with a mounted volume for the codebase which resides on my local host machine.
I was getting file_exists == FALSE (inside Composer autoload), but if I copied the filepath into terminal - it did exist! I tried the clearstatche(), checked safe-mode was OFF.
Then I remembered the Docker volume mapping: the absolute path on my local host machine certainly doesn't exist inside the Docker container - which is PHP's perspective on the world.
(I keep forgetting I'm using Docker, because I've made shell functions which wrap the docker run commands so nicely...)
It can also be a permission problem on one of the parent folders or the file itself.
Try to open a session as the user running your webserver and cd into it. The folder must be accessible by this user and the file must be readable.
If not, php will return that the file doesn't exist.
have you tried manual entry. also your two extensions seem to be in different case
var_dump(file_exists('../../images/example/001-001.jpg'));
var_dump(file_exists('../../images/example/001-001.PNG'));
A custom_file_exists() function inspired by #Timur, #Brian, #Doug and #Shahar previous answers:
function custom_file_exists($file_path=''){
$file_exists=false;
//clear cached results
//clearstatcache();
//trim path
$file_dir=trim(dirname($file_path));
//normalize path separator
$file_dir=str_replace('/',DIRECTORY_SEPARATOR,$file_dir).DIRECTORY_SEPARATOR;
//trim file name
$file_name=trim(basename($file_path));
//rebuild path
$file_path=$file_dir."{$file_name}";
//If you simply want to check that some file (not directory) exists,
//and concerned about performance, try is_file() instead.
//It seems like is_file() is almost 2x faster when a file exists
//and about the same when it doesn't.
$file_exists=is_file($file_path);
//$file_exists=file_exists($file_path);
return $file_exists;
}
This answer may be a bit hacky, but its been working for me -
$file = 'path/to/file.jpg';
$file = $_SERVER['REQUEST_SCHEME'].'://'.$_SERVER['HTTP_HOST'].'/'.$file;
$file_headers = #get_headers($file);
if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
$exists = false;
}else{
$exists = true;
}
apparently $_SERVER['REQUEST_SCHEME'] is a bit dicey to use with IIS 7.0 + PHP 5.3 so you could probably look for a better way to add in the protocol.
I found this answer here http://php.net/manual/en/function.file-exists.php#75064
I spent the last two hours wondering what was wrong with my if statement: file_exists($file) was returning false, however I could call include($file) with no problem.
It turns out that I didn't realize that the php include_path value I had set in the .htaccess file didn't carry over to file_exists, is_file, etc.
Thus:
<?PHP
// .htaccess php_value include_path '/home/user/public_html/';
// includes lies in /home/user/public_html/includes/
//doesn't work, file_exists returns false
if ( file_exists('includes/config.php') )
{
include('includes/config.php');
}
//does work, file_exists returns true
if ( file_exists('/home/user/public_html/includes/config.php') )
{
include('includes/config.php');
}
?>
Just goes to show that "shortcuts for simplicity" like setting the include_path in .htaccess can just cause more grief in the long run.
In my case, the problem was a misconception of how file_exists() behaves with symbolic links and .. ("dotdot" or double period) parent dir references. In that regard, it differs from functions like require, include or even mkdir().
Given this directory structure:
/home/me/work/example/
www/
/var/www/example.local/
tmp/
public_html -> /home/me/work/example/www/
file_exists('/var/www/example.local/public_html/../tmp/'); would return FALSE even though the subdir exists as we see, because the function traversed up into /home/me/work/example/ which does not have that subdir.
For this reason, I have created this function:
/**
* Resolve any ".." ("dotdots" or double periods) in a given path.
*
* This is especially useful for avoiding the confusing behavior `file_exists()`
* shows with symbolic links.
*
* #param string $path
*
* #return string
*/
function resolve_dotdots( string $path ) {
if (empty($path)) {
return $path;
}
$source = array_reverse(explode(DIRECTORY_SEPARATOR, $path));
$balance = 0;
$parts = array();
// going backwards through the path, keep track of the dotdots and "work
// them off" by skipping a part. Only take over the respective part if the
// balance is at zero.
foreach ($source as $part) {
if ($part === '..') {
$balance++;
} else if ($balance > 0) {
$balance--;
} else {
array_push($parts, $part);
}
}
// special case: path begins with too many dotdots, references "outside
// knowledge".
if ($balance > 0) {
for ($i = 0; $i < $balance; $i++) {
array_push($parts, '..');
}
}
$parts = array_reverse($parts);
return implode(DIRECTORY_SEPARATOR, $parts);
}
I just encountered this same problem and I solved it in a mysterious way. After inserting a a filepath I copied from Windows File explorer. file_exists() keeps returning false continuously, but if I copy same path from VSCode editor it works perfectly.
After dumping variables with var_dump($path); I noticed something mysterious.
For path I copied from file explorer it shows length 94.
For path I copied from VSCode Editor it shows length 88.
Both path look same length on my code Editor.
My suggestion: if string contain hidden characters, it may fail and not work.
$myfilepath = SITEROOT."/uploads/vaibhav_photo/thumbnail/".$user_avatar['thumbnail'];
if(file_exists($myfilepath))
{
echo "file exist";
}
else
{
echo "file does not exist";
}
It always goes to else part even though file is present.
if anybody have an alternate option for this in PHP please reply as fast as possible,
file_exists works on file paths only. http:// URLs are not supported.
$myfilepath = SITEROOT.DS.'uploads'.DS.'vaibhav_photo'.DS.'thumbnail'.DS.$user_avatar['thumbnail'];
NOTE::SITEROOT have actual root path and DS is constant DIRECTORY_SEPARATOR.
Pekka is correct that file_exists does not support http protocol.
You can however use file_get_contents
if(file_get_contents($myfilepath)) {
echo "file exist";
}
By default this pulls back the entire contents of the file. If this is not what you want you can optimise this by adding some flags:
if(file_get_contents($myfilepath, false, null, 0, 1)) {
echo "file exist";
}
This syntax will return the first character if it exists.
Check what your working directory is with getcwd().
Your path
example.com/uploads/etc/etc.jpg
is interpreted relative to the current directory. That's likely to be something like
/var/www/example.com
so you ask file_exists() about a file named
/var/www/example.com/example.com/uploads/etc/etc.jpg
You need to either figure out the correct absolute path (add the path containing all site roots in front of SITEROOT) or the correct relative path (relative to the directory your script is in, without a leading /).
tl;dr: try
$myfilepath = 'uploads/etc/etc.jpg';
