php導(dǎo)出csv格式數(shù)據(jù)實(shí)現(xiàn)：
先定義一個(gè)字符串 存儲(chǔ)內(nèi)容，例如
$exportdata = '規(guī)則111,規(guī)則222,審222,規(guī)222,服2222,規(guī)則1,規(guī)則2,規(guī)則3,匹配字符,設(shè)置時(shí)間,有效期'."\n";
然后對(duì)需要保存csv的數(shù)組進(jìn)行foreach循環(huán)，例如
if (!empty($lists)){
foreach($lists as $key => $value){
$time = date("Y-m-d_H:i:s", $value['add_time']);
$exportdata .= "\"\t".$value['Rule_id']."\",\"\t".$value['Rule_name']."\",\"\t".$value['Matching_level']."\",\"\t"."{$value['Rule_action']}"."\",\"\t".$value['Service_type']."\",\"\t".$value['Keyword1']."\",\"\t".$value['Keyword2']."\",\"\t".$value['Keyword3']."\",\"\t".$value['Matching_word']."\",\"\t".$value['Set_time']."\",\"\t".$value['Validation_time']."\"\n";
}
}
csv格式的內(nèi)容用','隔開，在現(xiàn)實(shí)的時(shí)候就能分格了。每一行后面就一個(gè)'\n'就能分行了。
然后在后面執(zhí)行輸出就行了。例如
$filename = "plcnetinfo_{$date}.csv";
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$filename");
header("Expires: 0");
header("Pragma: public");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
echo(mb_convert_encoding($exportdata,"gb2312","UTF-8"));
但是在導(dǎo)出數(shù)字的時(shí)候csv就會(huì)把前面的0去掉，例如 我想顯示 00001 ，如果輸出的話就會(huì)顯示1.這種解決辦法就是在輸出的時(shí)候就一個(gè)'\"\t',這個(gè)是制表符，會(huì)顯示成空格。就能把數(shù)值轉(zhuǎn)化成文本了。不過在導(dǎo)入的時(shí)候會(huì)出現(xiàn)'" '.這種東西，用一下php自帶的trim函數(shù)就好了。完整代碼如下：
//var_dump($sql);
$lists = $this->dbo->query($sql);
$exportdata = '規(guī)則111,規(guī)則222,審222,規(guī)222,服2222,規(guī)則1,規(guī)則2,規(guī)則3,匹配字符,設(shè)置時(shí)間,有效期'."\n";
$date = date("YmdHis");
if (!empty($lists)){
foreach($lists as $key => $value){
$time = date("Y-m-d_H:i:s", $value['add_time']);
$exportdata .= "\"\t".$value['Rule_id']."\",\"\t".$value['Rule_name']."\",\"\t".$value['Matching_level']."\",\"\t"."{$value['Rule_action']}"."\",\"\t".$value['Service_type']."\",\"\t".$value['Keyword1']."\",\"\t".$value['Keyword2']."\",\"\t".$value['Keyword3']."\",\"\t".$value['Matching_word']."\",\"\t".$value['Set_time']."\",\"\t".$value['Validation_time']."\"\n";
}
}
$filename = "plcnetinfo_{$date}.csv";
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$filename");
header("Expires: 0");
header("Pragma: public");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
echo(mb_convert_encoding($exportdata,"gb2312","UTF-8"));
