Workaround for Windows bug in is_writable() function

PHP has issues with Windows ACL's for determine if a directory is writable or not, this works around them by checking the ability to open files rather than relying upon PHP to interprate the OS ACL.



Quellcode

function win_is_writable( $path ) {

	if ( $path[ strlen( $path ) - 1 ] == '/' ) { // if it looks like a directory, check a random file within the directory
		return win_is_writable( $path . uniqid( mt_rand() ) . '.tmp' );
	} elseif ( is_dir( $path ) ) { // If it's a directory (and not a file) check a random file within the directory
		return win_is_writable( $path . '/' . uniqid( mt_rand() ) . '.tmp' );
	}
	// check tmp file for read/write capabilities
	$should_delete_tmp_file = ! file_exists( $path );
	$f                      = @fopen( $path, 'a' );
	if ( $f === false ) {
		return false;
	}
	fclose( $f );
	if ( $should_delete_tmp_file ) {
		unlink( $path );
	}
	return true;
