I'm working a small date time project. From my CSV file I have 4 columns, called Name, Employee ID, Data/Time, Status and in my Database columns are name, empID, date, timeIn, timeOut, Status.
Picture of my csv file: (Picture A)
And here is what I want to save in my database: (Picture B)
Example input CSV string:
Name,"Empoyee ID",Date/Time,Status
"Soriano, Jhoniel",901,"05/03/2019 1:01:03 PM",C/Out
"Soriano, Jhoniel",901,"05/04/2019 2:01:03 PM",C/In
"Soriano, Jhoniel",901,"05/04/2019 3:01:03 PM",C/Out
"Soriano, Jhoniel",901,"05/06/2019 4:01:03 PM",C/In
"Soriano, Jhoniel",901,"05/06/2019 5:01:03 PM",C/Out
"Soriano, Jhoniel",901,"05/07/2019 6:01:03 PM",C/In
How can I get started on this problem?
Edit
I want to thanks #jimmix for giving me some idea to get started.
Here is the real scenario:
From my CSV file, I have the data you can found at (Picture A), then I will upload using my upload() function in into my MySQL database with the table name "tbldumpbio",
See the table structure below:
From my table tbldumpbio data, I have a function called processTimesheet()
Here's the code:
public function processTimesheet(){
$this->load->model('dbquery');
$query = $this->db->query("SELECT * FROM tbldumpbio");
foreach ($query->result() as $row){
$dateTimeExplArr = explode(' ', $row->datetimex);
$dateStr = $dateTimeExplArr[0];
$timeStr = $dateTimeExplArr[1];
if($row->status='C/Out' and !isset($timeStr) || empty($timeStr) ){
$timeStrOut ='';
} else {
$timeStrOut = $dateTimeExplArr[1];
}
if($row->status='C/In' and !isset($timeStr) || empty($timeStr) ){
$timeStrIn ='';
} else {
$timeStrIn = $dateTimeExplArr[1];
}
$data = array(
'ID' => '',
'companyAccessID' => '',
'name' => $row->name,
'empCompID' => $row->empid,
'date' => $dateStr,
'timeIn' => $timeStrIn,
'timeOut' => $timeStrOut,
'status' => '',
'inputType' => ''
);
$this->dbquery->modInsertval('tblempbioupload',$data);
}
}
This function will add a another data into tblempbioupload. But here are the results that I'm getting with:
Please see the below data:
The problem is:
the date should not be duplicated
Time In data should be added if the status is 'C/In'
Time Out data should be added if the status is 'C/Out'
The expected result should be something like this:

Not the shortest one but working:
