Example of using PHPExcel to identify and format the date format in Excel
- Function Read_Excel_File2 ($ file_name, & $ result ){
- Require_once 'include/PHPExcel/Classes/PHPExcel/IOFactory. php ';
- $ Result = null;
- $ ObjReader = PHPExcel_IOFactory: createReader ('excel5 ');
- // $ ObjReader-> setReadDataOnly (true );
- Try {
- $ ObjPHPExcel = $ objReader-> load ($ file_name );
- } Catch (Exception $ e ){}
- If (! Isset ($ objPHPExcel) return "file resolution fails ";
- $ AllobjWorksheets = $ objPHPExcel-> getAllSheets ();
- Foreach ($ allobjWorksheets as $ objWorksheet ){
- $ Sheetname = $ objWorksheet-> getTitle ();
- $ HighestRow = $ objWorksheet-> getHighestRow (); // e.g. 10
- $ HighestColumn = $ objWorksheet-> getHighestColumn ();
- $ HighestColumnIndex = PHPExcel_Cell: columnIndexFromString ($ highestColumn );
- For ($ row = 1; $ row <= $ highestRow; ++ $ row ){
- For ($ col = 0; $ col <= $ highestColumnIndex; ++ $ col ){
- $ Cell = $ objWorksheet-> getCellByColumnAndRow ($ col, $ row );
- $ Value = $ cell-> getValue ();
- If ($ cell-> getDataType () = PHPExcel_Cell_DataType: TYPE_NUMERIC ){
- $ Cellstyleformat = $ cell-> getParent ()-> getStyle ($ cell-> getCoordinate ()-> getNumberFormat ();
- $ Formatcode = $ cellstyleformat-> getFormatCode ();
- If (preg_match ('/^ (\ [\ $ [A-Z] *-[0-9A-F] * \]) * [hmsdy]/I', $ formatcode )){
- $ Value = gmdate ("Y-m-d", PHPExcel_Shared_Date: ExcelToPHP ($ value ));
- } Else {
- $ Value = PHPExcel_Style_NumberFormat: toFormattedString ($ value, $ formatcode );
- }
- // Echo $ value, $ formatcode ,'
';
-
- }
- $ Result [$ sheetname] [$ row-1] [$ col] = $ value;
- }
- }
- }
- Return 0;
- }
The date judgment mainly includes the following parts:
- $ Cell = $ objWorksheet-> getCellByColumnAndRow ($ col, $ row );
- $ Value = $ cell-> getValue ();
- If ($ cell-> getDataType () = PHPExcel_Cell_DataType: TYPE_NUMERIC ){
- $ Cellstyleformat = $ cell-> getParent ()-> getStyle ($ cell-> getCoordinate ()-> getNumberFormat ();
- $ Formatcode = $ cellstyleformat-> getFormatCode ();
- If (preg_match ('/^ (\ [\ $ [A-Z] *-[0-9A-F] * \]) * [hmsdy]/I', $ formatcode )){
- $ Value = gmdate ("Y-m-d", PHPExcel_Shared_Date: ExcelToPHP ($ value ));
- } Else {
- $ Value = PHPExcel_Style_NumberFormat: toFormattedString ($ value, $ formatcode );
- }
- }
