php-functions's Issues
invalid argument supplied()
Hi,
I am trying to use this function in my project to retrive some files recursively.
But, I am getting the warning as given in the title.
The problem is with this line:
foreach (glob(dirname($pattern) . '/*', GLOB_ONLYDIR | GLOB_NOSORT) as $dir) {
According to PHP docs the function glob() returns empty array for no match and FALSE on error.
Then it gives a note saying
"On some systems it is impossible to distinguish between empty match and an error."
In the system I am currently working on, it is returning false when there is no match found leading to the warning.
I think you should modify the line so that it checks for the return value and then runs the loop.
For example.
if (!function_exists('glob_recursive')) {
// Does not support flag GLOB_BRACE
function glob_recursive($pattern, $flags = 0) {
$matched_files = glob($pattern, $flags);
$matched_dirs = glob(dirname($pattern) . '/*', GLOB_ONLYDIR | GLOB_NOSORT);
$dirs = $matched_dirs ? $matched_dirs : array();
$files = $matched_files ? $matched_files : array();
foreach ($dirs as $dir) {
$files = array_merge($files, glob_recursive($dir . '/' . basename($pattern), $flags));
}
return $files;
}
}
