Insert data to database from CSV file. Only inserts last row - php

Question

I read in data from a csv file, and want to insert it into my database. The issue is that it only inserts the last row in the CSV file each time. However when i print my $sq1 to screen it shows all 48 inserts with the different values that they should have. Could anyone tell me why it only inserts one row into the database?
<?php
// Did modify login values for privacy
$servername = "10.100.";
$username = "myusername";
$password = "abc123";
$dbname = "informationdata";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$file = fopen("ALMGrade.csv","r");
while(! feof($file)){
$ar =fgetcsv($file);
$sql = "INSERT INTO gradetable_copy (Grade, Grade1, Grade2, Grade3, Grade4, Grade5, Grade6)
VALUES ('$ar[0]', '$ar[1]', '$ar[2]', '$ar[3]', '$ar[4]', '$ar[5]', '$ar[6]' )";
echo $sql;
echo "<br>";
}
fclose($file);
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>

Answer 1

move the execution of query ($conn->query($sql) ) inside while:
while(! feof($file))
{
$ar =fgetcsv($file);
$sql = "INSERT INTO gradetable_copy (Grade, Grade1, Grade2, Grade3, Grade4, Grade5, Grade6)
VALUES ('$ar[0]', '$ar[1]', '$ar[2]', '$ar[3]', '$ar[4]', '$ar[5]', '$ar[6]' )";
echo $sql;
echo "<br>";
if ($conn->query($sql) === TRUE)
{
echo "New record created successfully";
}
else
{
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
fclose($file);
