Import a "|" delimited text file into MySQL DB using PHP? - php

Question

I'm trying to load a text file locally into a MySQL database using PHP. The data file looks like:
Device Name|DE:VI:CE:MAC:AD:DR:ES:SS|1376493754086|1376493754086
There are many lines of data formatted exactly as above.
I'm trying to load this data into a pre-established table like this:
$file = #fopen("LOCAL_data_file.txt","r");
$values = '';
while(!feof($file))
{
$con=mysqli_connect("127.0.0.1","root","password","my_db");
if(mysqli_connect_errno()){
echo "Error connecting to my_db: " . mysqli_connect_error();
}
$buffer = fgets($file, 4096);
list($a,$b,$c,$d)=explode("|",$buffer);
/*echo $a;
echo $b;
echo $c;
echo $d;*/
$ins="INSERT INTO 'tablet3' (Name, Address, StartTime, EndTime) VALUES
($a,$b,$c,$d)";
mysqli_query($con,$ins);
}
The data gets read from the file fine, because If I decomment the echoes of the list variables, it echos all of the data in the table. If I don't run the insert query, the table gets created with proper columns of "Name | Address | StartTime | Endtime" but with the insert query, the code returns a table with null data. I simply cannot figure out what I'm doing wrong.

Answer 1

I recreated it and this is the query I got to work
This is assuming the database structure of:
Name(varchar or text) Address(varchar or text) StartTime(int) EndTime(int)
Query:
$ins="INSERT INTO `tablet3` (Name, Address, StartTime, EndTime) VALUES
('$a','$b',$c,$d)";
Take note of the quotes around $a and $b. Also the tick marks around tablet3.
P.S. You don't really need anything around a table name.
