In this is the code of the library for importing csv files to sql is the key is in the first row. I want to remove the first row keys in csv file and add it to this code.

Fields in first row of csv that I want to be in the already in the code:

$fields = array(        '0'     => 'model',
                        '1'     => 'serial_num' ,
                        '2'     => 'client_name',
                        '3'     => 'end_user',
                        '4'     => 'trends_warranty_start',
                        '5'     => 'trends_warranty_end',
                        '6'     => 'trends_warranty_period',
                        '7'     => 'client_contract_no',
                        '8'     => 'vendor',
                        '9'     => 'support_coverage',
                        '10'    => 'sla',
                        '11'    => 'service_contract_num',
                        '12'    => 'support_coverage_start',
                        '13'    => 'support_coverage_end',
                        '14'    => 'support_coverage_period',
                        '15'    => 'trends_po',
                        '16'    => 'supplier_so');

无需更改代码，您只需将这些列添加到 csv 文件的第一行即可。并且将在代码中提供。

"serial_num" ,"client_name","end_user","trends_warranty_start","trends_warranty_end","trends_warranty_period","client_contract_no","vendor","support_coverage","sla","service_contract_num","support_coverage_start","support_coverage_end","support_coverage_period","trends_po","supplier_so"

另一个 possibel scanrio 是当你得到 csv 结果时，在结果数组中添加列名，如下所示

$result =   $this->csvreader->parse_file('Test.csv');

$columns    =    array(
                    'model',
                    'serial_num' ,
                    'client_name',
                    'end_user',
                    'trends_warranty_start',
                    'trends_warranty_end',
                    'trends_warranty_period',
                    'client_contract_no',
                    'vendor',
                    'support_coverage',
                    'sla',
                    'service_contract_num',
                    'support_coverage_start',
                    'support_coverage_end',
                    'support_coverage_period',
                    'trends_po',
                    'supplier_so'
);

$resultWithColumns  =   array_unshift($result , $columns);

现在您在结果数组中有列名。
