php - Way to remove/ignore last entry in multidementional array -


i use multifile uploader thats easy use end users, there issue adds field allow user select more files different folders.

the issue produce this

array (     [files] => array         (             [name] => array                 (                     [0] => 1450282558_circle-next-arrow-disclosure-glyph.png                     [1] => 40525882_ml.jpg                     [2] => pdf-sample.pdf                     [3] =>                  )              [type] => array                 (                     [0] => image/png                     [1] => image/jpeg                     [2] => application/pdf                     [3] =>                  )              [tmp_name] => array                 (                     [0] => /tmp/phpovbkoc                     [1] => /tmp/phpncisas                     [2] => /tmp/phpurks37                     [3] =>                  )              [error] => array                 (                     [0] => 0                     [1] => 0                     [2] => 0                     [3] => 4                 )              [size] => array                 (                     [0] => 405                     [1] => 218829                     [2] => 7945                     [3] => 0                 )          )  )

the last entry in every part empty, there way can around this? want remove/ignore lets [3] under name, type etc. avoide empty entry?

you can use array_slice this. if array stored in $data, works this:

foreach($data["files"] $attr => $file) {     $data["files"][$attr] = array_slice($data["files"][$attr], 0, -1); }  print_r ($data);

or use of by-reference operator (&), can done shorter:

foreach($data["files"] &$file) {     $file = array_slice($file, 0, -1); }

the output be:

array (     [files] => array         (             [name] => array                 (                     [0] => 1450282558_circle-next-arrow-disclosure-glyph.png                     [1] => 40525882_ml.jpg                     [2] => pdf-sample.pdf                 )              [type] => array                 (                     [0] => image/png                     [1] => image/jpeg                     [2] => application/pdf                 )              [tmp_name] => array                 (                     [0] => /tmp/phpovbkoc                     [1] => /tmp/phpncisas                     [2] => /tmp/phpurks37                 )              [error] => array                 (                     [0] => 0                     [1] => 0                     [2] => 0                 )              [size] => array                 (                     [0] => 405                     [1] => 218829                     [2] => 7945                 )          )  )

the call array_slice has these arguments:

  • the array take slice (i.e. sub-array);
  • the index slice starts: specify 0;
  • the length of slice. -1 takes except last element.
