[修订]解析CSV文件和保存CSV
1.
解析CSV文件:
/**
* 检查文件
*/
function isFileOK($file){
//判断文件大小
$size = $file['size']/1000000;//M，默认上限是2MB
if($size > 2) {
dumpErrorCode($GLOBALS['language']['goods_file_error_size']);
}
//判断文件类型
$allowed_types = array('csv');
$filename = $file['name'];
$ext = strtolower(end(explode('.', $filename)));
if(!in_array($ext,$allowed_types)){
dumpErrorCode($GLOBALS['language']['goods_file_error_extension']);
}
$this->targetFolder =
APPLICATION_ROOT.UPLOAD_PATH.$_SESSION['platform_code'].'/';
if(file_exists($this->targetFolder)){
$ret = true;
}else{
$ret = mkdir($this->targetFolder);
}
if(!$ret){
dumpErrorCode($GLOBALS['language']['goods_file_error_directory']);
}
$result = move_uploaded_file($file['tmp_name'], $this->targetFile);
if ($result) {
$count = file_put_contents($this->targetFile,
$this->trans2utf8($this->targetFile));
if (!$count) {
dumpErrorCode("
".$GLOBALS['language']['asset_error4']."");
}
}else {
dumpErrorCode($GLOBALS['language']['asset_upload_fail']);
}
$handle = fopen($this->targetFile, 'r');
if(!$handle){
dumpErrorCode($GLOBALS['language']['goods_file_error_open']);
}
return $handle;
}
$handle = $this->isFileOK($file);
Function test(){
$i = 0;
while(($row = fgetcsv($handle)) !== FALSE){
$i++;
//标

行为第一行，跳过，并把各列标题保存在一个数组中，根据标题名
得到相应的行号，从而获得数据
if($i==1){
//通过标题获取对应列的列号
$header = $row;
$taskid = array_search("任务编号",$header);
$taskname = array_search("任务名称",$header);
$tasktype = array_search("类型",$header);
continue;
}
$arr = array();
$arr[0] = $row[$taskid];
//插入数据库操作
...
}
}
12.保存CSV文件:
/**
* 导出csv文档
*/
function makecsv(){
$taskCsv = array(...);//数据数组
header("Content-Type: application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: inline; filename=\"{$this->table}_tmp.csv\"");
$csvTitle = array(...);//标题数组
readfile($this->savecsv($csvTitle, $taskCsv));
}
/**
* 保存数据为csv.
* @param $column
* @param $rows
*/
function savecsv($column,$rows)
{
if(is_array($rows)){
$pathFile =
APPLICATION_ROOT.CREATE_PATH.$_SESSION['platform_code'].'/';
if(!file_exists($pathFile)){
mkdir($pathFile, 0777);
}
$pathFile .= $this->table.'_tmp.csv';
$handle = fopen($pathFile, 'w');
if($handle){
fwrite($handle, chr(0xEF).chr(0xBB).chr(0xBF));
fwrite($handle, implode(',', $column).PHP_EOL);//将标题通过,连
接
foreach($rows as $row){
fwrite($handle, implode(',', $row).PHP_EOL);//将数据通过,连
接，然后写入csv文件
}
fclose($handle);
return $pathFile;
}else{
return false;
}
}else{
return false;
}
