我有一個腳本來導出一個MySQL數據庫的內容,它的工作很好,除了具有前導零的列外。由於某些原因,這些被丟棄。PHP Excel導出丟棄前導零

有沒有一種方法可以修改代碼來保留這些前導零?

非常感謝!

$sql = "Select * from $DB_TBLName"; 
 
$Connect = @mysql_connect($DB_Server, $DB_Username, $DB_Password) or die("Couldn't connect to MySQL:<br>" . mysql_error() . "<br>" . mysql_errno()); 
 
//select database 
 
$Db = @mysql_select_db($DB_DBName, $Connect) or die("Couldn't select database:<br>" . mysql_error(). "<br>" . mysql_errno()); 
 
//execute query 
 
$result = @mysql_query($sql,$Connect) or die("Couldn't execute query:<br>" . mysql_error(). "<br>" . mysql_errno());  
 
$file_ending = "xls"; 
 
//header info for browser 
 
header("Content-Type: application/xls");  
 
header("Content-Disposition: attachment; filename=$filename.xls"); 
 
header("Pragma: no-cache"); 
 
header("Expires: 0"); 
 
/*******Start of Formatting for Excel*******/ 
 
//define separator (defines columns in excel & tabs in word) 
 
$sep = "\t"; //tabbed character 
 
//start of printing column names as names of MySQL fields 
 
for ($i = 0; $i < mysql_num_fields($result); $i++) { 
 
echo mysql_field_name($result,$i) . "\t"; 
 
} 
 
print("\n");  
 
//end of printing column names 
 
//start while loop to get data 
 
    while($row = mysql_fetch_row($result)) 
 
    { 
 
     $schema_insert = ""; 
 
     for($j=0; $j<mysql_num_fields($result);$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 = preg_replace("/\r\n|\n\r|\n|\r/", " ", $schema_insert); 
 
     $schema_insert .= "\t"; 
 
     print(trim($schema_insert)); 
 
     print "\n"; 
 
    }

爲了保持前導零,Excel中必須把數據作爲文本(或一些自定義數字格式,如「00000000」)。

我發現superuser.com的潛在解決方案。基本上,按以下格式的數據將被視爲文本,因爲該值將用雙引號內:「=」「00123」「」

我覺得你的代碼將變爲:

[snip] 
     elseif ($row[$j] != "") 
      $schema_insert .= '"=""$row[$j]"""'.$sep; 
[snip] 

或者不管怎樣會產生樣本中顯示的必要報價。
