我有一張表包含以下數據。零不顯示爲excell文件中的前綴
emp_name emp_id
Test1 0011
Test2 0532
我正在使用php下載excell中的數據。下面是代碼。
<?php
/*******EDIT LINES 3-8*******/
$DB_Server = "localhost"; //MySQL Server
$DB_Username = "usr"; //MySQL Username
$DB_Password = "pass"; //MySQL Password
$DB_DBName = "db_name"; //MySQL Database Name
$DB_TBLName = "table_name"; //MySQL Table Name
$timezone = +6;
$date_time=gmdate("Y_m_d-H-i-s", time() + 3600*($timezone+date("I")));
$filename = "ALL_Report_$date_time"; //File Name
/*******YOU DO NOT NEED TO EDIT ANYTHING BELOW THIS LINE*******/
//create MySQL connection
$sql = "SELECT name,emp_id from emp_info";
$Connect = @mysql_connect($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";
}
?>
使用這個腳本我得到的數據正確,但是當我打開它的excell。前綴0不顯示在excell表單中。
數據顯示爲以下格式。
emp_name emp_id
Test1 11
Test2 532
請幫助我如何獲得前綴爲零的數據。
