无法下载/处理sql以使用PHP优秀

我有这个奇怪的问题。 我想运行一个脚本，从表中获取数据并使用php脚本下载到excel格式。 它在本地机器上运行正常，但不在Linux服务器上运行。 我尝试了2个不同的服务器，但都没有工作。 这是代码。

<?php include "config.php"; $count = 0; $sqlquery = "select * from contact_us" ; $result = mysql_query($sqlquery) or die(mysql_error()); $count = mysql_num_fields($result); for ($i = 0; $i < $count; $i++) { $header .= mysql_field_name($result, $i)."\t"; } while($row = mysql_fetch_row($result)) { $line = ''; foreach($row as $value) { if(!isset($value) || $value == "") { $value = "\t"; } else { # important to escape any quotes to preserve them in the data. $value = str_replace('"', '""', $value); # needed to encapsulate data in quotes because some data might be multi line. # the good news is that numbers remain numbers in Excel even though quoted. $value = '"' . $value . '"' . "\t"; } $line .= $value; } $data .= trim($line)."\n"; } # this line is needed because returns embedded in the data have "\r" # and this looks like a "box character" in Excel $data = str_replace("\r", "", $data); # Nice to let someone know that the search came up empty. # Otherwise only the column name headers will be output to Excel. if ($data == "") { $data = "\nno matching records found\n"; } $count = mysql_num_fields($result); # This line will stream the file to the user rather than spray it across the screen header("Content-type: application/vnd.ms-excel"); //header("Content-type: text/plain"); # replace excelfile.xls with whatever you want the filename to default to header("Content-Disposition: attachment; filename=excelfile.xls"); header("Pragma: no-cache"); header("Expires: 0"); //echo $header."\n".$data; echo $header."\n".$data."\n"; ?> 

我试过的另一个代码，但显示的价值，而不是下载到Excel格式

  <?php include "config.php"; header('Content-Type: application/vnd.ms-excel'); header('Content-disposition: attachment; filename="MasterEntryList.xls"'); ?> <?php $i=0; if(isset($_POST['dsubmit'])) { $pro=$_POST['project']; if(($_POST['fromdate']=="") || ($_POST['todate']=="")) { $fromdate=""; $todate=""; $date = ""; } else { $fromdate=$_POST['fromdate']; $todate=$_POST['todate']; $date = "yes"; } //Start Single Condition if( ($pro!="") && ($date=="") ) { $cond="WHERE project_ LIKE '$pro'"; }else if(($pro=="") && ($date!="") ) { $cond="WHERE (date_ BETWEEN '$fromdate' AND '$todate')"; }else if( ($pro!="") && ($date!="") ) { $cond="WHERE project_ LIKE '$pro' AND (date_ BETWEEN '$fromdate' AND '$todate')"; }else if( ($pro=="") && ($date=="") ) { $cond=" "; } $sql="SELECT * FROM contact_us {$cond}"; $query=mysql_query($sql); } else { $query=mysql_query("SELECT * FROM contact_us order by id DESC Limit 100 "); } ?> <table class="table table-striped table-bordered table-hover" id="dataTables-example" border="1"> <thead> <tr> <th> Sr.No.</th> <th>Client Name</th> <th>Country Code</th> <th>Contact</th> <th>City</th> <th>UTM Campaign</th> <th>UTM Source</th> <th>UTM medium</th> <th>Date</th> </tr> </thead> <tbody> <?php $follow=date("Ymd"); while( $result_data=mysql_fetch_assoc($query) ) { $i++; ?> <tr> <td><?php echo $i; ?></td> <td><?php if($result_data['name_']==""){echo "NA";}else {echo $result_data['name_'];}?> </td> <td><?php if($result_data['country_']==""){echo "00";}else {echo $result_data['country_'];}?></td> <td><?php if($result_data['number_']==""){echo "0000000000";}else {echo $result_data['number_'];}?></td> <td><?php if($result_data['city_']==""){echo "NA";}else {echo $result_data['city_'];}?></td> <td><?php if($result_data['utm_campaign']==""){echo "NA";}else {echo $result_data['utm_campaign'];}?></td> <td><?php if($result_data['utm_source']==""){echo "NA";}else {echo $result_data['utm_source'];}?></td> <td><?php if($result_data['utm_medium']==""){echo "NA";}else {echo $result_data['utm_medium'];}?></td> <td><?php if($result_data['date_']==""){echo "0000-00-00";}else {echo $result_data['date_'];}?></td> </tr> <?php } ?> </tbody> </table>

这可能会帮助你

请使用mysqli_*函数，因为mysql_*函数现在是旧的。

 function export_to_excel($array, $filename="test.xls", $delim = "\t", $newline = "\n", $enclosure = '"' ) { $string_to_export = ""; $c = 0; foreach( $array as $row) { // Header if(!$c) { $string_to_export .= $enclosure.implode($enclosure.$delim.$enclosure, array_keys($row) ).$enclosure.$newline; } $string_to_export .= $enclosure.implode($enclosure.$delim.$enclosure, array_values($row) ).$enclosure.$newline; $c++; } header('Content-type: application/vnd.ms-excel;charset=utf-8'); header('Content-Disposition: attachment; filename='.$filename); header("Cache-Control: no-cache"); echo $string_to_export; die(); } $link = mysqli_connect("host", "user", "password", "db"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $sqlquery = "select * from contact_us" ; if ($result = mysqli_query($link, $sqlquery)) { // php 5.3 + if you have then // use mysqli_fetch_all function otherwise mysqli_fetch_assoc while ($row = mysqli_fetch_assoc($result)) { $array[] = $row; } export_to_excel($array); }
