Php generates an EXCEL document instance program. The following describes several php implementation programs used to generate EXCEL documents. For more information, see. Original original method of writing: Send the header, and send the header of the attachment to the user's browser table. The following describes several php implementation programs that generate EXCEL documents. if you need them, refer to them.

Original Style
Original method: Send the header, and send the header of the attachment to the user's browser to indicate that the object is to be downloaded. then, read the data in the database, parse it one by one, and write it into an excel file.

The code is as follows:

$ DB_Server = "localhost ";
$ DB_Username = "root ";
$ DB_Password = "";
$ DB_DBName = "DBName ";
$ DB_TBLName = "DB_TBLName ";
$ Savename = date ("YmjHis ");
$ Connect = @ mysql_connect ($ DB_Server, $ DB_Username, $ DB_Password) or die ("Couldn't connect .");
Mysql_query ("Set Names 'gbk '");
$ File_type = "vnd. ms-excel ";
$ File_ending = "xls ";
Header ("Content-Type: application/$ file_type; charset = gbk ");
Header ("Content-Disposition: attachment; filename =". $ savename. ". $ file_ending ");
Header ("Pragma: no-cache ");
$ Now_date = date ("Y-m-j H: I: s ");
$ Title = "database name: $ DB_DBName, Data Table: $ DB_TBLName, backup date: $ now_date ";
$ SQL = "Select * from $ DB_TBLName ";
$ ALT_Db = @ mysql_select_db ($ DB_DBName, $ Connect) or die ("Couldn't select database ");
$ Result = @ mysql_query ($ SQL, $ Connect) or die (mysql_error ());
Echo ("$ titlen ");
$ Sep = "t ";
For ($ I = 0; $ I <mysql_num_fields ($ result); $ I ++)
{
Echo mysql_field_name ($ result, $ I). "t ";
}
Print ("n ");
$ I = 0;
While ($ row = mysql_fetch_row ($ result ))
{
$ Schema_insert = "";
For ($ j = 0; $ j {
If (! Isset ($ row [$ j]) $ schema_insert. = "NULL". $ sep;
Elseif ($ row [$ j]! = "") $ Schema_insert. = "$ row [$ j]". $ sep;
Else $ schema_insert. = "". $ sep;
}
$ Schema_insert = str_replace ($ sep. "$", "", $ schema_insert );
$ Schema_insert. = "t ";
Print (trim ($ schema_insert ));
Print "n"; $ I ++;
}
Return (true );
?>

PHPExcel Library

The following is an excel method that uses PHPExcel to achieve the same functions as above. GetCol is a recursive function used to return the corresponding column number encoding based on numbers. This is because the row number and column number must be specified during the export process. The row number is a simple number, and the column number is a combination of A-Z. To facilitate the import of two-dimensional arrays, column number encoding is automatically obtained based on the number of columns.

Instructions for use:

1. Save the following code as excel. php and call it on the page.

2. call xlsBOF (), write some content to xlswritenunber () or xlswritelabel (), and finally call xlsEOF.

You can also use the fwrite function to directly write data to the server, instead of simply displaying data in the browser with echo.

The following is the PHP code:

The code is as follows:

// ----- Begin of function library -----
// Excel begin of file header
Function xlsBOF (){
Echo pack ("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0 );
Return;
}
// Excel end of file footer
Function xlsEOF (){
Echo pack ("ss", 0x0A, 0x00 );
Return;
}
// Function to write a Number (double) into Row, Col
Function xlsWriteNumber ($ Row, $ Col, $ Value ){
Echo pack ("sssss", 0x203, 14, $ Row, $ Col, 0x0 );
Echo pack ("d", $ Value );
Return;
}
// Function to write a label (text) into Row, Col
Function xlsWriteLabel ($ Row, $ Col, $ Value ){
$ L = strlen ($ Value );
Echo pack ("ssssss", 0x204, 8 + $ L, $ Row, $ Col, 0x0, $ L );
Echo $ Value;
Return;
}
?>

The following is the call code:

Header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT ");
Header ("Last-Modified:". gmdate ("D, d m yh: I: s"). "GMT ");
Header ("Cache-Control: no-cache, must-revalidate ");
Header ("Pragma: no-cache ");
Header ('content-type: application/x-msexcel ');
Header ("Content-Disposition: attachment; filename=EmplList.xls ");
Header ("Content-Description: PHP/INTERBASE Generated Data ");
//
// The next lines demonstrate the generation of the Excel stream
//
Include ("excel. php ");
XlsBOF (); // begin Excel stream
XlsWriteLabel (0, 0, "This is a label"); // write a label in A1, use for dates too
XlsWriteNumber (0, 1, 9999); // write a number B1
XlsEOF (); // close the stream
?>
