I'd like to put each file name in $xsl_dir_path (absolute path) in select element. I've tried this:
$files = glob($xsl_dir_path . "/*.xsl");
array_walk($files, 'basename');
but it's not working at all, i can still see the full names of the files. I know i can apply basename when lopping through $files and build the option elements, but i'd like to do it before any html output.
array_walk is useful when your callback function accepts a reference or when you use user-defined callback functions. In this case, the basename argument is not a reference.
What you want is array_map:
$files = glob($xsl_dir_path . "/*.xsl");
$files = array_map('basename', $files);
Try this:
function basename_for_walk (&$value, $key) {
$value = basename($value);
}
$files = glob($xsl_dir_path . "/*.xsl");
array_walk($files, 'basename_for_walk');
That's because basename() isn't supposed to change the value of the array cells, only to return the new values. You need to pass to array_walk() a function that actually changes the value of the cell. Based on array_walk docs:
function my_basename(&$item)
{
$item = basaname($item);
}
$files = glob($xsl_dir_path . "/*.xsl");
array_walk($files, 'my_basename');
glob()will always serve the full file paths. If you don't want that, you need to cut it off afterwardsbasename()doesn't conform with the kind of callback thatarray_walk()needs - you would have to build a custom function that modifies the first argument directly
