Removing the first row in a csv file upload to mysql database
Question
I have the following code for uploading a csv file to a mysql database. Its working just fine, but if the csv file contains a heading for each column its getting uploaded in the first row of the table. I want to remove the first row of the csv file while getting stored in the database. How can i do that ?
<?php
//connect to the database
$connect = mysql_connect("localhost","root","");
mysql_select_db("crm",$connect); //select the table
//
if ($_FILES[csv][size] > 0) {
//get the csv file
$file = $_FILES[csv][tmp_name];
$handle = fopen($file,"r");
//loop through the csv file and insert into database
do {
if ($data[0]) {
mysql_query("INSERT INTO lead (name, lead_value, status) VALUES
(
'".addslashes($data[0])."',
'".addslashes($data[1])."',
'".addslashes($data[2])."'
)
");
}
} while ($data = fgetcsv($handle,1000,",","'"));
//
//redirect
header('Location: import.php?success=1'); die;
}
?>

example code from what I'm using, and it should work because I'm using it in production environment
$handle = fopen("stuff.csv","r");
/* assuming that first row has collumns names */
$query = "INSERT INTO table(";
$cols = fgetcsv($handle,100000,';','"');
$query .= implode(", ",$cols).") VALUES";
$values = "";
/* cycle through each row and build mysql insert query */
while($data = fgetcsv($handle,100000,';','"')) {
$values .= " ( ";
foreach($data as $text) {
$values .= "'".$text."', ";
}
$values = substr($values,0,-2);
$values .= "), ";
}
/* remove last 2 chars */
$values = substr($values,0,-2);
$query .= $values;
echo $query;
fclose($handle);
Mind the fact that this script will return the mysql query... not execute it, so alter it to your needs.

I think you mean that you want to not insert the first row of the CSV data into your table. Working on that assumption (note that I'm not a PHP programmer, so the changes I've made should be taken as pseudocode):
if ($_FILES[csv][size] > 0) {
$first_time = true;
//get the csv file
$file = $_FILES[csv][tmp_name];
$handle = fopen($file,"r");
//loop through the csv file and insert into database
do {
if ($first_time == true) {
$first_time = false;
continue;
}
if ($data[0]) {
mysql_query("INSERT INTO lead (name, lead_value, status) VALUES
(
'".addslashes($data[0])."',
'".addslashes($data[1])."',
'".addslashes($data[2])."'
)
");
}
} while ($data = fgetcsv($handle,1000,",","'"));
//redirect
header('Location: import.php?success=1'); die;
}

If I am understanding you correctly you want to remove the header row? I would use LOAD DATA instead of INSERT INTO
LOAD DATA INFILE '/tmp/test.csv' INTO TABLE test FIELDS TERMINATED BY ',' IGNORE 1 LINES;
LOAD DATA is vastly superior performance-wise than INSERT.
