scandir
Syntax
array scandir ( string $directory [, int $sorting_order [, resource $context] ] )
Popis
Príkaz jazyka PHP
Returns an array of files and directories from the directory.
- directory - The directory that will be scanned.
- sorting_order - By default, the sorted order is alphabetical in ascending order. If the optional sorting_order is used (set to 1), then the sort order is alphabetical in descending order.
- context - For a description of the context parameter, refer to the streams section of the manual.
Returns an array of filenames on success, or FALSE on failure. If directory is not a directory, then boolean FALSE is returned, and an error of level E_WARNING is generated.
Tip: S touto funkcí můžete používat URL jako název souboru, pokud je zapnuta volba "fopen wrappers".
