i have a cakephp application that works on several webservers (LAMP). But on one server i get an error when saving or deleting items.

I guess it may have something to do with the tmp/cache folder which should have some content when using the app. It has 777 permission.

This is the error:

Digging ionto your code: one of the 2 arrays probably happens to be empty or non-set at line
                       $files = array_merge($files, glob($cache));

1 - Below I show your code with some debugging info display  as well.
2 - It might even happen that it works without the error you have met, because I have set the arrays (presumed parts of the merge) with a array() assignation.
3 - If it does not, can you paste the error messages?

<?PHP
function clearCache($params = null, $type = 'views', $ext = '.php') {
    if (is_string($params) || $params === null) {
          $params = preg_replace('/\/\//', '/', $params); //** what if null?
          $cache = CACHE . $type . DS . $params; // CACHE and DS were declared as constants, right?
$debug = true; //easy to change
if ($debug) {echo "** After entry - params is [$params], cache is [$cache]";}

          if (is_file($cache . $ext)) {
                @unlink($cache . $ext);
                return true;
          } elseif (is_dir($cache)) {
                $files = glob("$cache*");

                if ($files === false) {
                      return false;
                }

                foreach ($files as $file) {
                      if (is_file($file)) {
                            @unlink($file);
                      }
                }
                return true;  //any subdirectory in $files will be left intact
          } else { // not is_file and not is_dir
                $cache = CACHE . $type . DS . '*' . $params . $ext;
if ($debug) {echo "** Before first glob - params is [$params], cache is [$cache]";}
                $files = array(); $files = glob($cache);
if ($debug) {echo "Found in this cache " . count($files) . "elements (files or directories)<br>";}

                $cache = CACHE . $type . DS . '*' . $params . '_*' . $ext;

                $files2 = array();$files2 = glob($cache);

                $files = array_merge($files, $files2); //was glob($cache));

There are no files, therefore the 2 glob calls return "false"... and there our php version diverge
Mine interprets this "false" as no elements, and the count is zero
Yours interprets this false as one element... and anyway tries to merge the arrays.

Solution:
- lazzy and bad: use @array_merge, there will be no error message and the result will probably be false as expected by the rest of the program
- real solution: test for false before the merge
replace                $files = array_merge($files, $files2); //was glob($cache));
with    
if (!($files2 === false)) { //if false: let $files unchanged
     if ($files === false) { $files = $false2; }
          else {$files = array_merge($files, $files2); }
     ; // endif files
}; // endif files2
