我正在尝试创建一个导入工具来读取csv文件并允许我将其映射到表列并导入它。我正在尝试使用代码点火器。
有没有人这样做并拥有一个库或者有一个工具可用于php和/或codeigniter。在我尝试重新发明轮子之前,我想检查一下。

很久以前我做了类似的事情,我感觉很慷慨,所以这里有一段代码片段! : - )
我让用户从前端的表单中选择相应的字段,但如果您的CSV文件永远不会更改,则可以随时对其进行硬编码。
显然你会想要修改你的需要(分隔符,字段名等等),但这应该让你开始朝着正确的方向前进。
// get POST values
$objPost = (object) $this->input->post('arr_of_fields');
$fh_csv = fopen('YOUR CSV FILE');
$fh_tmp = fopen('YOUR TEMP FILE');
while( false !== ($line = fgets($fh_csv)) )
$enclosed = ''; // or whatever your field is enclosed with
$delimiter = ','; // or whatever your delimiter is
$columns = explode($enclosed.$delimiter.$enclosed, trim($line, $enclosed));
// the $objPost->field_X signifies the index for that field [0,1,2,3,+++]
$data = array(
'field_1' => trim(@$columns[@$objPost->field_1], $enclosed),
'field_2' => trim(@$columns[@$objPost->field_2], $enclosed),
'field_3' => trim(@$columns[@$objPost->field_3], $enclosed),
'field_4' => trim(@$columns[@$objPost->field_4], $enclosed),
);
// write line to temp csv file, tab delimited with new line
$str = implode("\t", $data) . "\n";
@fwrite($fh_tmp, $str); // write line to temp file
}
@fclose($fh_csv);
@fclose($fh_tmp);
// import from temp csv file into database
$sql = sprintf("LOAD DATA LOCAL INFILE '%s'
INTO TABLE `%s`
FIELDS TERMINATED BY '\\t'
LINES TERMINATED BY '\\n'
(field_1, field_2, field_3, field_4)",
"TEMP FILE",
"DATABASE TABLE NAME");
$query = $this->db->query( $sql );
// delete temp file
@unlink("TEMP FILE");
