Copying a single file to multiple sub-directories

[johnc71]

Can this be done?

 

I want to copy a single file "index.html" to any sub-directory in the current location that begins with "demo".

 

Of course I can do this by running the code below, but how can I do this by using LOOP.

 

so it would be something like this

 

Go thru all sub-directories

for each sub-directory where the first four characters of sub-directory == 'demo')

{

copy index.html to that sub-directory

}

 

This is the current non-practical code I have

$file = 'index.html';
$dest1 = 'demo/index.html';
$dest2 = 'demoABC/index.html';
$dest3 = 'demo123/index.html';

copy($file, $dest1);
copy($file, $dest2);
copy($file, $dest3);

You had a beautiful pseudo-code example, why not implement it?

 

<?php
$indexHtml = 'path/to/index/html/file';
$directoryListing = scandir('path/to/directory');
foreach ($directoryListing as $directory) {
   if (is_dir($directory) && is_writeable($directory)) {
       $directoryName = basename($directory);
       if (substr($directoryName, 0, 4) === 'demo') {
          copy($indexHtml, $directory .DIRECTORY_SEPARATOR. 'index.html');
       }
   }
}
?>

Sorry, I did not mention that the PHP version is 4.  I modified your code to make it compatible with 4.0 and although it may not be the cleanest approach, it works. 

 

Now the challenge I have is, if the folder name matches but the folder is not writable, how do I get around it?  Can I temporarily change the permisions on that folder either via chown or chmod  to make it writable and than restore the original permissions?

 

Here is the current code:

<?php

$indexHtml = 'index.html';
$current_directory = "/usr/local/apache/htdocs/";
$dir_contents = opendir($current_directory);
while ($sub_directory = readdir($dir_contents)){
  if($sub_directory != "." && $sub_directory != ".."){
 	if (is_dir($current_directory."/".$sub_directory) && is_writeable($current_directory."/".$sub_directory)){ 
    	$directoryName = basename($sub_directory);
       		if(substr($directoryName, 0, 4) === 'demo'){
          	  copy($indexHtml, $sub_directory .DIRECTORY_SEPARATOR. 'index.html');
	      }
      } 
     }
}
closedir($dir_contents);

?>

Upgrade. No excuses.

LOL @ Daniel0's response. Yeah, you really should upgrade.

 

Anyways, you can change the permissions temporarily. Look into fileperms() and chmod().

Ok... The file is copied but it ends up with 0 bytes.  What gives?

No write permission?

[johnc71]

Ok, I resolved the issue with zero bytes files.  So, the final problem I have now is with target directory permisions.

 

If I want to copy file A to folder B, I can't because the folder B rights are set to 755.   

 

I tried to chmod the folder B to 777 before copying file, but since the php file is in group "www" I do not have right to chmod folder B. 

 

Arghhh... 

 

If I ssh to the server and change folder owner to www, am I compromising the security of that folder?
