)

Syntax

scandir(directory, order, context)

Parameters

ParameterDescription
directorySpecifies the directory to be scanned (required)
orderSpecifies the sorting order (default sort order is alphabetical in ascending order (0)); set to SCANDIR_SORT_DESCENDING or 1 to sort in alphabetical descending order, or SCANDIR_SORT_NONE to return the result unsorted
contextA context is a set of parameters and wrapper specific options which modify or enhance the behavior of a stream; contexts are created using stream_context_create() and can be passed to most filesystem related stream creation functions (i.e. fopen(), file(), file_get_contents(), etc...)

PHP Notes:

  • When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
  • Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on

We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
