i am loading a CSV file through PHP and inserting into a temporary table, this is what my loading PHP script and MySQL query.
$i=0;
while (($data = fgetcsv($source, 1000, ",")) !== FALSE)
{
if($i!=0) {
$column1=$data[0];
$column2=$data[1];
$column3=$data[2];
$column4=$data[3];
$column5=$data[4];
$column6=$data[5];
$query= "INSERT INTO temp_table(column1,column2,column3,column4,column5,column6,load_datetime)
VALUES (nullif('$column1',''), nullif('$column2',''), nullif('$column3',''), nullif('$column4',''), nullif('$column5',''), nullif('$column6',''),now())";
mysql_query($query) or die(mysql_error());
}
$i++;
}
and my CSV file has 25000 records, this is a sample row from my CSV
column1,column2,column3,column4,column5,column6
,,,13:57:18,,23:00:19
the problem i face is, it takes more than 10 minutes when i load the CSV and in between the page goes blank. My PHP settings: upload_max_filesize: 100M post_max_size:100M max_execution_time:1000 max_input_time:1000.
this my table detail
CREATE TABLE temp_table (
id int(11) NOT NULL,
column1 time DEFAULT NULL,
column2 time DEFAULT NULL,
column3 time DEFAULT NULL,
column4 time DEFAULT NULL,
column5 time DEFAULT NULL,
column6 time DEFAULT NULL,
load_datetime datetime DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
and when i check the temp_table it has inserted around 8000 records. please help me with an approach to insert faster.
