phpexcel - Extracting images from an Excel file (xlsx) using PHP -

-

how can read images excel file using phpexcel , save images in server , display them? extension of file .xlsx.

my code:

$objphpexcel = phpexcel_iofactory::load($path);  foreach ($objphpexcel->getactivesheet()->getdrawingcollection() $drawing) {     if ($drawing instanceof phpexcel_worksheet_memorydrawing) {         ob_start();         call_user_func(             $drawing->getrenderingfunction(),             $drawing->getimageresource()         );         $imagecontents = ob_get_contents();          ob_end_clean();     }  }

thanks!!

$objphpexcel->getactivesheet()->getdrawingcollection()

will return arrayobject of image objects in active worksheet.

these objects either phpexcel_worksheet_drawing or phpexcel_worksheet_memorydrawing objects: can identify using [is_a()][1]. can use methods appropriate class (as described in api) either read image data file (for phpexcel_worksheet_drawing objects) or directly phpexcel_worksheet_memorydrawing object itself. getname() , getdescription() methods can used retrieve relevant values fro image object.

note it's possible have image objects associated print headers:

$objphpexcel->getactivesheet()->getheaderfooter()->getimages()

can used retrieve images header/footer. array of phpexcel_worksheet_headerfooterdrawing objects. phpexcel_worksheet_drawing methods can used extract image file these objects.

edit

spoonfeeding time.

this extract images active worksheet, , write them files on server.

$objphpexcel = phpexcel_iofactory::load($path);  $i = 0; foreach ($objphpexcel->getactivesheet()->getdrawingcollection() $drawing) {     if ($drawing instanceof phpexcel_worksheet_memorydrawing) {         ob_start();         call_user_func(             $drawing->getrenderingfunction(),             $drawing->getimageresource()         );         $imagecontents = ob_get_contents();         ob_end_clean();         switch ($drawing->getmimetype()) {             case phpexcel_worksheet_memorydrawing::mimetype_png :                     $extension = 'png'; break;             case phpexcel_worksheet_memorydrawing::mimetype_gif:                     $extension = 'gif'; break;             case phpexcel_worksheet_memorydrawing::mimetype_jpeg :                     $extension = 'jpg'; break;         }     } else {         $zipreader = fopen($drawing->getpath(),'r');         $imagecontents = '';         while (!feof($zipreader)) {             $imagecontents .= fread($zipreader,1024);         }         fclose($zipreader);         $extension = $drawing->getextension();     }     $myfilename = '00_image_'.++$i.'.'.$extension;     file_put_contents($myfilename,$imagecontents); }

files named

00_image_n.extension

where n number starting 1, , extension appropriate extension (png,jpg,gif, whatever) image type.
